Solution true Keynesian economics (/?ke?nzi?n/ kayn -zee-?n ; or Keynesianism ) is the view that in the short run, especially during recessions, economic output is strongly influenced by aggregate demand (total spending in the economy). In the Keynesian view, aggregate demand does not necessarily equal theproductive capacity of the economy; instead, it is influenced by a host of factors and sometimes behaves erratically, affecting production, employment, and inflation. [1] The theories forming the basis of Keynesian economics were first presented by the British economist John Maynard Keynes in his book, The General Theory of Employment, Interest and Money , published in 1936, during theGreat Depression. Keynes contrasted his approach to the aggregate supply-focused \'classical\' economics that preceded his book. The interpretations of Keynes that followed are contentious and several schools of economic thoughtclaim his legacy. Keynesian economists often argue that private sector decisions sometimes lead to inefficient macroeconomic outcomes which require active policy responses by the public sector, in particular, monetary policy actions by thecentral bank and fiscal policy actions by the government, in order to stabilize output over the business cycle. [2] Keynesian economics advocates a mixed economy .

In 2000, June, A 75-year-old widow, creates an irrevocable trust naming her five adult grandchildren as the beneficiaries. The assets transferred in trust consist of marketable securities (worth $800,000) and June\'s personal residence (worth $400,000). Bob, June\'s younger brother and a practicing attorney, is designated as the trustee. Other provisions of the trust are as follows: Bob is given the discretion to distribute the income to the beneficiaries based on their need or add it to corpus. He is also given the power to change trust investments and to terminate the trust. The trust is to last for June\'s lifetime or, if sooner, until termination by Bob. Upon termination of the trust, the principal and any accumulated income are to be distributed to the beneficiaries (June\'s grandchildren). For 2000, June files a form 709 to report the transfer in trust and pays a gift tax based on value of $1.2 million ($800,000 + $400,000). After the transfer in trust and up to the time of her death, June continues to occupy the residence. Although she pays no rent, she maintains the property and pays the yearly property taxes. June never discussed the matter of her continued occupancy of the residence with either Bob or the beneficiaries of the trust. Upon June\'s death in 2008, the value of the trust is $2.3 million, broken down as follows: marketable securities and cash ($1.6 million) and residence ($700,000). Shortly thereafter, Bob sells the residence, liquidates the trust, and distributes the proceeds to the beneficiaries. What are the estate taxes consequences of these transaction to June? Solution Since she pays her property taxes, there are no tax consequences on June. However on selling the house, her children will have to pay tax on capital gains from the increase n the value of the house. To avoid this tax, they will have to live in the same house for two years. .

IMF in Greece. Good or bad for the country? Why? Solution IMF is international monetary fund.It was established with the motive of promoting international monetary cooperation.It is good because: 1. It helps in abolishing the exchange restrictions among member nations. 2. It helps in maintaining balanced economic development of the member nations by poviding them monetary help. 3. It helps the member countries in making investment in profitable projects. 4. It offers monetary help to member countries in correcting the disequilibrium of balance of payment. IMF is bad because: 1. it is a club of rich countries only. it discriminate between rich and poor memebers. 2. it do not provides loan for developmental projects. it only gives loans for maintaining the favourable balance of payment. 3. it interferes in the domestic economies of member countries. while providing loan to member counties IMF put many restrictions. 4. IMF tried to maintain stability in price of gold but failed in achieving this aim. .

2. What is a colloid? Why is it difficult to filter a colloid? 3. What is coagulation? What is peptization? 4. Why is the solution of AgNOs added slowly? 5. Why must a large excess of AgNOs be avoided? 6. Why must the silver chloride be protected from the light? 7. For simplicity assume that your unknown chloride is NaCl. Calculate how many mL of the 5% AgNO3 solution must be added to 0.4020 g of the NaCl sample to precipitate all the chloride. Note: 5% means that there are 5 grams of silver nitrate per 100 mL of solution. Solution 2) Colloid : Colloid is a dispersion of small tiny particles in a liquid.. In collods the tiny particles remain suspended in the solvent. rather than settling at the bottom. It is difficult to filter collodal solution because these tiny particles pass through the filter paper. 3) Coagulation : means the aggrigation of oppositely charged particles which settle down under the gravity. Peptization : It is a phenomenon of the formation of a colloidal dispersion from precipitation. 4)Addition of the AgNO3 be done slowly because the addition tends to yield large particles which makes filtration more efficiently .It also helps limit coprecipitation. 5)To avoid coprecipatation the excess of AgNO3 be avoided. 6)Silver chloride must be protected from light as it is unstable. Exposure to light it becomes greyish yellow . Hence, to avoid decompostion, it must be protected from light. .

2. The Mars Climate Orbiter (formerly the Mars Surveyor 98 Orbiter) was one of two spacecraft in the Mars Surveyor 98 program, the other being the Mars Polar Lander (formerly the Mars Surveyor 98 Lander). The two missions were to study the Martian weather, climate, and water and carbon dioxide badget in order to understand the reservoirs, behavior, and atmospheric role of volatiles and to warch for evidence of long-term and episodic climate changes. The Mars Climate Orbiter was destroyed when a navigation error caused the spacecraft to miss its intended 140-150 km altitude above Mars during orbit insertion, instead entering the Martian atmosphere at about 57 km. The spacecraft was destroyed by atmospherie stresses and friction at this low altitude. A review board found that some data was calculated on the ground in Imperial units (pound-seconds) and eported that way to the navigation team, who were expeeting the data in metric units (newton-seconds). Calculate the conversion between Newton-seconds and pound-seconds. (Hint: pound is the force of 1 slug being accelerated at 1 foot/see2, and 1 slug is 14.59 kg.) s. (Hint: 1 pound is the force of 1 slug being accelerated at 1 foot/see, and 1 slug Solution 1 newtons = 0.224808942443 pounds hence 1 newton -second = Â Â 0.224808942443 pounds -seconds .

Identify the alkene with the largest molar heat of hydrogenation (most exothermic). Solution 2) option B is correct Explanation: Reaction of alkene with H2O, H2SO4 involves formation of carbocation as an intermediate. Benzyl cation is more stable so it reacts fastest then tertiary carbocation is more stable than secondary so structure III is faster than II. 3) option A is correct Explanation: Addition of HCl to alkene produces carbocation as an intermediate. Now, the nucleophile attacks the carbocation and produces racemic mixture of products. 4) option B is the starting material Explanation: NaOEt is a base which gives elimination reaction and produces alkene as product. Oxymercuration-demercuration of alkene with Hg(OAc)2, THF and NaBH4 produces more substituted alcohol which on further cyclization produces the required product. .

2. In each of the following pairs of substances, predict which one would have the higher boiling point (if done on this sheet, circle the correct answer): a) He or Ar c) GeH4 or SiH4 e) hexane or heptane b) Ar or N20 d) HF or HCI f) F2 or I2 Solution a) He or Ar: He and Ar are both noble gases and the only kind of intermolecularforces that exist in them are the london dispersion forces.The size of the atom increases as you go down the periodic table, and so will be the number of electrons. As number of electrons increase, the polarizability also increases, resulting in greater London Dispersion forces. So Ar which is down in the group has more london dispersion forces as compared to He and hence will have ahigher boiling. Ar has a higher boiling point. b) NO 2 or Ar: Ar, is a noble gases and the only kind of intermolecularforces that exist in Ar are the london dispersion forces. NO 2 on the other hand has a strong dipole which leads to dipole-dipole interactions along with london dispersion forces. These extra intra-molecuar forces bind NO 2 molecules together, making it difficult to break these bonds, there by leading to a higer boiling point, So NO 2 has higher boiling point. c) GeH 4 orSiH 4: Ge is below Si in the group which means that GeH 4 has more electrons than SiH 4. Therefore GeH 4 has more London dispersion forces and hence needs more energy to break these forces; leading to higher boiling point. GeH 4 has higher boiling point. d) HF or HCl: HF and HCl are both acids of anions from group VII (halides). However Floride is more electroegative comapred to Chloride. Being more electronegative the floirde is very strongly attracted to hydrogen than chloride would do. So it is more diffult to break an HF bond compared to HCl and hence HF has a higher boiling point. .

2. The Reynolds number for a particular microchannel flow is found to be Re = 2. a. If all channel dimensions (length, width, and height) are reduced by a factor of 10, and the time required for a particle to traverse the length of the channel is invariant, what is the value of Re for the smaller channel? b. If the flow velocity is constant for both channels, rather than the time scale, what is the value of Re for the smaller channel? Solution Initial Case Re = rho*V*L/mu = 2 Time req to travel the distance t = L/V------(1) a) When dimensions are reduced by 10 L1, W1, H1 L1 = L/10 W1 = W/10 H1 = H/10 Time required to travel the distance L1 is t = L1/V1-----(2) Given 1 = 2 L1/V1 = L/V (Since L1 = L/10) V1 = 0.1*V Re = Rho*V1*L1/mu = (1/00)*rho*V*L/mu = 0.02 b) Now Velocity remains constant Re = rhi*V*L1/mu =0.1*rho*V*L/mu = 0.2 .

20pts) Discuss the advantages and disadvantages of using chlorine as a disinfectant and also name east two alternative disinfectants for drinking water treatment. Solution Advantages of chlorination 1. Chlorine is a powerful oxidizing agent thereby kills bacteria and fungi in water. 2. Chlorine is commercially available 3. Chlorine is very economical 4. chlorine is more cost-effective than other disinfection methods (except when dechlorination is needed and fire code requirements must be met). 5. The chlorine residual that remains in the discharged wastewater can prolong disinfection even after initial treatment and also provides a measure of the effectiveness. Disadvantages 1. The chlorine residual, even at low concentrations, is toxic to aquatic life and may require dechlorination. 2. All forms of chlorine are highly corrosive and toxic. Thus, storage, shipping, and handling pose safety risks. 3. Chlorine oxidizes organic matter in wastewater, sometimes creating compounds that could be harmful to humans and the environment. 4. The chloride content of the wastewater is increased. 5. Certain types of microorganisms have shown resistance to low doses of chlorine. 6. The long-term effects of discharging dechlorinated compounds into the environment are unknown. In addition to chlorination there are many methods. Few of them are 1. OZONALYSIS (Addition of ozone) 2.
