Ammonia (NH3) decomposes to hydrogen and nitrogen and 22.0 kilocalories of energy was absorbed per mole of NH3. Show your calculation by dimensional analysis.(10 pts) 2NH3 (g) 3H2(g) + N2(g) ΔH = + 22.0 kcal/mol a. How much energy is absorbed when 50.5 kilograms of NH3 was decomposed? Show your solution by dimensional analysis. (Answer = 65,400 kilocalories). Molar...
3. If sodium methoxide in methanol was used in place of potassium t butanol, your GC analysis would look much more like the 2-butanol/sulfuric acid reaction products. In addition, a new, non-alkene product would be present in the GC analysis from a competing, non-elimination mechanism. Explain why the alkene distribution would change, what the new product would be, and why...
can you please explain and answere these short answeres. it is from biochem. 14. Given diagram of Succinate to Fumarate to Malate to Oxaloacetate and you have to add the cofactors and products (NOT enzymes). 15. a) Given diagram of Succinyl CoA to Succinate and you have to add the cofactors, products, AND the enzyme. b) What is the specific...

2. In this experiment you will quantitatively measure a reaction rate of 5,0 2. with I in solu- tion to produce I, according to the following reaction: 5,0,- +21 slow -> 1, +2 SO,2- The color change is very sudden and dramatic when 2 x 10+ mol of I, is produced. The time required to produce 2 x 10 mol...
pre lab- heat of combustion (1-3D) Experiment 10 HEAT OF COMBUSTION Pre-Lab 1. The Law of Conservation of Energy can be applied to combustion processes where fuel + oxygen products + energy The total chemical energy associated with the reactants must be the same as the total chemical energy of the products when the heat of combustion is included. a)...
