The molecule listed below that would have the lowest boiling point is A.HCl B. CH4 C.NH3 D.H20 The molecule listed below that would have the lowest boiling point is A.HCl B. CH4 C.NH3 D.H20 A.HCl B. CH4 C.NH3 D.H20 Solution Answer: A. Molar mass of HCl=36.46 g/mol and its boiling point= -85.05Â°C B. Molar mass of CH4=16.04 g/mol and its boiling point= -164Â°C C. Molar mass of NH3=17.031 g/mol and its boiling point= -33.34 Â°C D. Molar mass of H2O=18.015 g/mol and its boiling point= 100Â°C Water has the highest boiling point since it forms hydrogen bonding. So it has highest boiling point. Lowest boiling point is CH4, because the intermolecular forces in CH4 are London dispersion forces. These are weak forces. .

Please only answer if you know the answer. I have posted this twice and both times received incorrect answers that didn\'t even match up to the journal format. The account tile options are: salaries expense, Terrell Capital, Donley Capital, Account receivable, distributions, accounts payable, Pinkston capital, Lamar Capital and Cash. At April 30, partners\' capital balances in PDL Company are: G. Donley $51,400, C. Lamar $50,100, and J. Pinkston $15,200. The income sharing ratios are 5 4: 1, respectively. On May 1, the PDLT Company is formed by admitting Â·Terrell to the firm as a partner Journalize the admission of Terrell under each of the following independent assumptions. (Credit account titles are automatically indented when amount is entered. Do not indent manually.) (1) (2) (3) (4) Terrell purchases 50% of Pinkston\'s ownership interest by paying Pinkston $16,140 in cash. Terrell purchases 331/3% of Lamar\'s ownership interest by paying Lamar $15,450 in cash. Terrell invests $63,100 for a 30% ownership interest, and bonuses are given to the old partners Terrell invests $43,500 for a 30% ownership interest, which includes a bonus to the new partner No. Account Titles and Explanation Debit Credit 1. 2. 3. Lamar\'s capital balance is $31,570 after admitting Terrell to the partnership by investment. If Lamar\'s ownership interest is 20% of total partnership capital, what were Terrell\'s cash investment and the bonus to the new partner? Terrell\'s cash investment Bonus to new partner Solution I have already answered this question once. .

Please make comments of the following discussion in 150-200 words.If you agree or disagree.why or why not? EEO laws apply to recruiting activities because a firm is required by the laws to utilize a sufficiently diverse workforce without violating the privacy of others and without and kind of bias based on sex, race, religon, disabilities, and other such things. Without these laws, recruiting activities could become invasive, obtrusive, unfair, and biased in a multitude of ways. The five main things i would do to help promote diversity in the workforce: 1.) Allow for flex-hours and as much remote working as possible for single parents and the elderly or disabled 2.) Hire on all mediums and through many agencies to try and reach the most demographically diverse audience possible 3.) Offer full-time, part-time, and temporary jobs in a way that is dynamic around the employees available hours 4.) Go through the Office of Disability Employement to provide work for the disabled 5.) Offer counseling and training for uneducated or low skill employees Solution Flexible working hours would offer an immense advantage to the employees as it would help to maintain a balance between their personal life and work obligations. Providing the facility of work from home or flexible work hours would help to employ single parents, elderly people and disabled. Thus, it would create diversity in the workforce. Different agencies including the Office of Disability Employment would help to acquire diverse pool of employee. Full-time, temporary and part-time jobs would help to attract students, other part-time workers, housewives etc. Hiring uneducated or low-skills employees after providing them some training would also help to increase the diversity in workforce. Above techniques are efficient to maintain a diverse work environment at the workplace without any kind of bias including sex, race, religion, or disabilities. .

please help with answer and explain homo and lumo in terms of acid/base. thanks! 10) A molecule with a high HOMO and a low LUMO can act as: (A) a Lewis base only (B) a Lewis acid only (C) a Lewis base and Lewis acid (D) neither a Lewis base, nor a Lewis acid (E) an inert molecule 11) A molecule with a low HOMO and a high LUMO can act as: (A) a Lewis base only (B) a Lewis acid only (C) a Lewis base and Lewis acid (D) an inert molecule (E) none of the above Solution 10) a molecule with a high HOMO and low LUMO can act as a Lewis Base or Lewis Acid. 11) a molecule with low HOMO and high LUMO can act as an inert molecule. According to lewis acid base concept, the Homo and Lumo are the pair of orbitals that lie closest. When having a high HOMO, this is lewis base. When having a low LUMO , this is lewis acid. When the HOMO and LUMO are far they have a larger energy gap, and the HOMO-LUMO interactions do not happen. And when the HOMO and LUMO of a molecule are closer they interact with each other. .

Please help me with this crossword! Solution Across: 4.Constitutional Isomers Cis and trans isomers are formed when the substituents are on opposite sides. These are constitutional Isomers. 5. Levorotatory When rotation of plane polarized light is towards the left, it is called levorotatory, and if to the right then dextrorotatory. 6. Stereoisomers Isomeric compounds with same connections but different spatial arrangements. 8. Stereocenters 11.Chiral Have non-superimposible mirror images 13. Constitutional Isomers Have different connectivities. 14. Raesmic Mixture Have no optical activity due to external compensation by as equal amounts of + and - enantiomers cancel each other. 15.

Please Type Answer! Compare and contrast the properties of acids and bases. Solution Acids are species which have the ability to accept a pair of electrons. Acids are sour in taste, corrosive in nature, and turn blue litmus paper to red. Reaction of acids with a base results into loss of acidity (acidic nature) of acid. while the bases have the ability to donate a pair of electron. And, bases turn red litmum paper to blue. Bases lose their basic nature when they react with an acid. The reaction between an acid and a base is called acid-base reaction. Two examples are discussed below #1 HCl + NaOH ----> NaCl + H 2 O (H + + OH - -----> H 2 O) #2 BH 3 + NH 3 ----> BH 3 NH 3 In reaction 1, as H + ion of HCl can accept a pair of electron (from OH - of NaOH), thus HCl is an acid and NaOH is a base. Going by the same argument BH 3 in reaction 2, can accept a pair of elctron from NH 3 , thus BH3 is an acid, while NH3 is a base. Acids and bases contrast in their ability to change the color of litmum. Acids turn blue litmum paper to red, while bases changes the red litmum to blue. .
