When methanol, CH, OH, is burned in the presence of oxygen gas, 02, a large amount of heat energy is released. For this reason, it is often used as a fuel in high performance racing cars. The combustion of methanol has the balanced, thermochemical equation CH, OH(g) + O2(g) → CO2(g) + 2 H2O(1) AH = -764 kJ How much methanol, in grams, must be burned to produce 609 kJ of heat? mass: mass: g
Acid Catalyzed Hydration-treatment of alkenes with water in the presence of acid catalyst leads to the formation of alcohols. H2SO4/H2O > 150°C Mechanism Major Product Acid catalyzed dehydration goes through a carbocation intermediate. This means that the Markovnikov product is obtained when carbocation rearrangements do not occur. The need for excessively high temperatures makes this reaction of limited use in laboratory synthesis. Oxymercuration - Oxymercuration involves the addition of Hg to the alkene using mercury (II) acetate Hg(OAc) followed by...
Question 1 0.5 When table sugar is burned in presence of oxygen, carbon dioxide and water vapor are produced according to the unbalanced chemical equation: C12H22011(s) + 02(9) - CO2(g) + H2O(g) How many moles of oxygen are required to react completely with 2.70 mol of sugar? 47 O 32.4 - 65 2.70 O None of these Question 2 0.5 pts Consider the reaction of magnesium metal with hydrochloric acid to produce magnesium chloride and hydrogen gas. If 3.65 mol...

3) The following Grignard reaction is performed: CH,сH, Нас, H2C OH H 1. CH,CH2MgBr in ether H 2. H30+ Calculate how much of a 0.7000M solution of ethylmagnesiumbromide is required to react completely with 45.00 g of the starting material. Assume you need a 15% excess of the Grignard reagent. Then predict the amount of product which will be produced from reacting 55.00 g of starting material based on a 78% product yield.
D Question 3 2 pts When and how does the RT-PCR test detect the presence of the virus? After PCR, by adding a quencher dye which is activated when the viral DNA is available in high concentrations During PCR by adding fluorescent primers that are detected through a special laser After PCR, by adding a fluorescent dye which will be activated once the sample goes through a special laser. During PCR, by adding a fluorescent dye and a quencher dye...
