la) Define briefly the following terms: MSDS, IDLH Sublimation, Emulsion, lb) What is the physical state of acetic anhydride at room temperature? Write the structural formula of acetic anhydride, also look up the molecular weight, the boiling point and density of acetic anhydride. Solution a) MSDS or Material Safety Data Sheet is a document that comes with a material and mentions all the potential hazards of the material like health hazards, fire hazards, environmental hazards and reactivity. IDLH or Immediately Dangerous to Life or Health is defined as exposure to airborne contaminants which may cause death or adverse health effects. Sublimation is the process by which a substance which is in solid phase, directly goes to gaseous phase with rise in temperature. There\'s no intermediate liquid phase. For example, naphthalene. Emulsion is a fine dispersion of one liquid in another liquid in which it is not completely soluble. It is a liquid-liquid colloid. b) acetic anhydride is a colorless liquid at room temperature . Structural formula CH3COOCOCH3. There is a double bond between second C and O , and third C and O. The other oxygen atom is attached to both the C\'s. Molecular weight:102.09g/mol Boiling point: 140 degrees Celsius Density: 1.08 g/cm^3 .

THERMAL STABILITY OF SELECTED DEEP EUTECTIC SOLVENTS
n this study, a new type of " green solvents " named deep eutectic solvents (DESs) has been synthesized combining hydrogen bond acceptors (HBAs) and hydrogen bond donors (HBDs). Choline chloride (ChCl) was chosen as typical HBA, and lactic acid, tartaric acid, citric acid and oxalic acidwere chosen as HBDs. The thermal stability of deep eutectic solvents is an important parameter for their application and limits the maximum operation temperature. The thermal stability of DESs such as lactic, tartaric, citric and oxalic acid with choline chloride showed wide range of application (134.8 – 197.8°C). All DESs were observed in temperature range 25 – 400°C.

Explain how various materials reflect, absorb, or transmit light Explain why a yellow pencil looks yellow to you
Solution
Reflection : It is the phenomenon of changing the direction of ray at the interface saperating two different mediums in such a way that the ray goes back in the same medium at the same angle with the interface at which it hit it.
Refraction : Refraction is the phenomenon of a ray changing the direction at the interface separating two different medium in such a way that the ray moves from one medium to another medium.
Diffaraction : It is the phenonmenon of bending of lights around the obstacles.
Primary colors : Red , green and Blue are known as the three primary colors because by mixing these colors we can make any other color.

Kidding has uncovered evidence that seems to indicate that Rocket Man has been overbilling the government for a weapons system project. On the one hand he feels he has a duty to bring this wrongdoing to light. After all, he reasons, there is the greater public interest and common good to consider. On the other hand, the project is so critical to the financial future of the Company that the disclosure of wrongdoing could be devastating for the Company and its employees, many of whom are R.U.
Solution
Government subcontractors over bill the government in types of projects-from waste clean up sites, to defense contractors, to road,to low income housing projects, to infrastructure projects.Any information that can prove overbilling must be given to government .The laws that govern federal over billing, or fraud lawsuits are also known as Qui Tams

Kathryn and her husband earned a considerable fortune during their wor.docx
Kathryn and her husband earned a considerable fortune during their working lives, but Kathryn is now retired and her husband is deceased. Kathryn has $20 million available to pass along to her two children, and has made provisions in her will to divide her estate equally between the children. The $20 million currently sits in a safe deposit box in a bank, where unfortunately it earns no return (though of course it also does not lose value).
Question:
Assume that the estate and gift tax rate is 40 percent, and there is a $10 million exemption, so any portion of an estate or lifetime gifts above $10 million is subject to a 40 percent tax. If Kathryn leaves the $20 million in her safe deposit box until she dies, then how much will each of her children receive after taxes?
Solution
Hi,
Please find the correct answers as follows:
Since there is an exemption of $10 million, any amount over and above will have to bear the taxes
Tax Payable = ($20 million - $10 million)*40%
=$4 million
Amount left after tax payment = $20 million - $4 million
=$16 million
Hence, the amount each child will recieve = $16 million/2
=$8 million

Katy-'s Catering Co- places an order with Sharpe-'s Supply House for 1.docx
Katy\'s Catering Co. places an order with Sharpe\'s Supply House for 100 white linen tableclothes. A week later, Sharpe\'s delivers the order to Kathy\'s in ten boxes. Katy opens up a few boxes, determines that they contain white linen tablecloths, and hands over a check for $1,000 to Sharpe\'s deliveryman. Sharpe\'s Supply then properly negotiates Katy\'s check to its wholesaler, Harper Linens, as payment on Sharpe\'s account. The next day, Katy opens up the reamining boxes and discovers that about a third of the order is messed up. Some of the tablecloths are blue instead of white, some are polyester instead of linen. She immediately calls her back and places a stop-payment order on the check. The next day, Harper\'s deposited Katy\'s check for payment, but of course payment was refused because of the stop-payment order. Harper\'s then files a lawsuit against Katy\'s Catering seeking to collect on the check
Will Harper\'s prevail in its lawsuit against Katy\'s?
Why or why not?
Be sure to describe & define Harper Linen\'s legal status
Solution
Katy\'s catering co. has the right to stop payment without incurring penalties. This is because, as per law, a cheque\'s payment can be stopped if the debtor has a good faith dispute over the sum of money being paid. Here, Katy\'s catering co. has a reasonable belief of its legal entitlement to withhold payment.
Katy\'s had asked for 100 white linen tableclothes and the cheque was drawn as an amount payable for this. However, it received around 33 blue or polyster tableclothes. Hence it has the good faith dispute and Katy cannot be penalized for stopping the payment of the cheque.

Kare Kars provides shuttle service between four hotels near a medical.docx
Kare Kars provides shuttle service between four hotels near a medical center and an international airport. Kare Kars uses two 10-passenger vans to offer 12 round trips per day. A recent month
Solution
(a) Calculate the break-even point in (1) dollars and (2) number of fares.
(1) Break-even point in dollar= Fixed Cost/ contribution margin ratio
Fixed Cost = 13090
contribution margin ratio = contribution margin/Fare revenues
Contribution margin ratio = 21560/30800
Contribution margin ratio = 0.70
Break-even point in dollar = 13090/0.7
Break-even point in dollar= $ 18700
(2) Break-even point in units = Break-even point in dollar / Fare Price
Fare Price = 30800/1400 = 22
Break-even point in units = 18700/22
Break-even point in units = 850 fares
(b) Without calculations, determine the contribution margin at the break-even point.
Contribution margin at the break-even point = $ 13090
Note: Contribution margin at the break-even point is always equal to Fixed Cost

Learning Goal- To recognize acids- bases- and conjugate pairs- By the.docx
Learning Goal:
To recognize acids, bases, and conjugate pairs.
By the Arrhenius definition, an acid directly produces H+ ions in aqueous solution and a base directly produces OH? ions in aqueous solution. For example, HClproduces H+ and NaOH produces OH?:
acid:base:HCl(aq)NaOH(aq)??H+(aq)+Cl?(aq)Na+(aq)+OH?(aq)
To recognize Arrhenius acids, look for H at the beginning of the formula. To recognize Arrhenius bases, look for OH at the end of the formula.
By the Brønsted-Lowry definition, an acid donates a H+ ion and a base accepts a H+ ion. For example, HCl donates a H+ ion to water and C5H5N accepts a proton from water. By showing water in the equation, we see a more complete picture of what is actually going on:
acid:base:HCl(aq)+H2O(l)C5H5N(aq)+H2O(l)??H3O+(aq)+Cl?(aq)C5H5NH+(aq)+OH?(aq)
To recognize Brønsted-Lowry acids, look for H at the beginning of the formula. To recognize Brønsted-Lowry bases, first make sure it\'s not an acid, and then look for N in the formula.

Katy-'s Catering Co- places an order with Sharpe-'s Supply House for 1.docx
Katy\'s Catering Co. places an order with Sharpe\'s Supply House for 100 white linen tableclothes. A week later, Sharpe\'s delivers the order to Kathy\'s in ten boxes. Katy opens up a few boxes, determines that they contain white linen tablecloths, and hands over a check for $1,000 to Sharpe\'s deliveryman. Sharpe\'s Supply then properly negotiates Katy\'s check to its wholesaler, Harper Linens, as payment on Sharpe\'s account. The next day, Katy opens up the reamining boxes and discovers that about a third of the order is messed up. Some of the tablecloths are blue instead of white, some are polyester instead of linen. She immediately calls her back and places a stop-payment order on the check. The next day, Harper\'s deposited Katy\'s check for payment, but of course payment was refused because of the stop-payment order. Harper\'s then files a lawsuit against Katy\'s Catering seeking to collect on the check
Will Harper\'s prevail in its lawsuit against Katy\'s?
Why or why not?
Be sure to describe & define Harper Linen\'s legal status
Solution
Katy\'s catering co. has the right to stop payment without incurring penalties. This is because, as per law, a cheque\'s payment can be stopped if the debtor has a good faith dispute over the sum of money being paid. Here, Katy\'s catering co. has a reasonable belief of its legal entitlement to withhold payment.
Katy\'s had asked for 100 white linen tableclothes and the cheque was drawn as an amount payable for this. However, it received around 33 blue or polyster tableclothes. Hence it has the good faith dispute and Katy cannot be penalized for stopping the payment of the cheque.

Kare Kars provides shuttle service between four hotels near a medical.docx
Kare Kars provides shuttle service between four hotels near a medical center and an international airport. Kare Kars uses two 10-passenger vans to offer 12 round trips per day. A recent month
Solution
(a) Calculate the break-even point in (1) dollars and (2) number of fares.
(1) Break-even point in dollar= Fixed Cost/ contribution margin ratio
Fixed Cost = 13090
contribution margin ratio = contribution margin/Fare revenues
Contribution margin ratio = 21560/30800
Contribution margin ratio = 0.70
Break-even point in dollar = 13090/0.7
Break-even point in dollar= $ 18700
(2) Break-even point in units = Break-even point in dollar / Fare Price
Fare Price = 30800/1400 = 22
Break-even point in units = 18700/22
Break-even point in units = 850 fares
(b) Without calculations, determine the contribution margin at the break-even point.
Contribution margin at the break-even point = $ 13090
Note: Contribution margin at the break-even point is always equal to Fixed Cost

Learning Goal- To recognize acids- bases- and conjugate pairs- By the.docx
Learning Goal:
To recognize acids, bases, and conjugate pairs.
By the Arrhenius definition, an acid directly produces H+ ions in aqueous solution and a base directly produces OH? ions in aqueous solution. For example, HClproduces H+ and NaOH produces OH?:
acid:base:HCl(aq)NaOH(aq)??H+(aq)+Cl?(aq)Na+(aq)+OH?(aq)
To recognize Arrhenius acids, look for H at the beginning of the formula. To recognize Arrhenius bases, look for OH at the end of the formula.
By the Brønsted-Lowry definition, an acid donates a H+ ion and a base accepts a H+ ion. For example, HCl donates a H+ ion to water and C5H5N accepts a proton from water. By showing water in the equation, we see a more complete picture of what is actually going on:
acid:base:HCl(aq)+H2O(l)C5H5N(aq)+H2O(l)??H3O+(aq)+Cl?(aq)C5H5NH+(aq)+OH?(aq)
To recognize Brønsted-Lowry acids, look for H at the beginning of the formula. To recognize Brønsted-Lowry bases, first make sure it\'s not an acid, and then look for N in the formula.
Part A
Classify each of these compounds as an Arrhenius acid, an Arrhenius base, or neither.
HClO3
KNO3
Hg(OH)2
KOH
Mn(OH)2
C3H8
HBr
Ca(OH)2
HF
H3PO4
Arhenius acid
Arhenius base
Neither
Solution
Arrhenius Acid : HClO3 , HBr , HF , H3PO4
Arrhenius base : Hg(OH)2 , KOH , Mn(OH)2 , Ca(OH)2
Neither : KNO3 , C3H8

la) Define briefly the following terms- MSDS- IDLH Sublimation- Emulsi.docx
- 1. la) Define briefly the following terms: MSDS, IDLH Sublimation, Emulsion, lb) What is the physical state of acetic anhydride at room temperature? Write the structural formula of acetic anhydride, also look up the molecular weight, the boiling point and density of acetic anhydride. Solution a) MSDS or Material Safety Data Sheet is a document that comes with a material and mentions all the potential hazards of the material like health hazards, fire hazards, environmental hazards and reactivity. IDLH or Immediately Dangerous to Life or Health is defined as exposure to airborne contaminants which may cause death or adverse health effects. Sublimation is the process by which a substance which is in solid phase, directly goes to gaseous phase with rise in temperature. There's no intermediate liquid phase. For example, naphthalene. Emulsion is a fine dispersion of one liquid in another liquid in which it is not completely soluble. It is a liquid-liquid colloid. b) acetic anhydride is a colorless liquid at room temperature . Structural formula CH3COOCOCH3. There is a double bond between second C and O , and third C and O. The other oxygen atom is attached to both the C's. Molecular weight:102.09g/mol Boiling point: 140 degrees Celsius Density: 1.08 g/cm^3
