Liquid hydrogen peroxide is an oxidizing agent in rocket fuel mixtures because it decomposes to form oxygen, which is then used in the combustion of the rocket fuel. The reaction is: 2 H2O2 (1) → 2 H2O(1) + O2(8) AH = -196.1 K/mol If a 33.72 g sample of hydrogen peroxide is placed in a bomb calorimeter containing 372.9 g of water at 24.6 °C and allowed to react, what will be the final temperature of the water? Assume that the calorimeter absorbs a negligible amount of heat.

3. Kindly answer this and show your solution.

A chemical engineer is studying the following reaction: BF 3(aq)+NH3(aq) → BF ,NH3(aq) At the temperature the engineer picks, the equilibrium constant K for this reaction is 1.3. The engineer charges ("fills") three reaction vessels with boron trifluoride and ammonia, and lets the reaction begin. He then measures the composition of the mixture inside each vessel from time to time. His first set of measurements are shown in the table below. Predict the changes in the compositions the engineer should expect next time he measures the compositions. reaction expected change in concentration compound concentration vessel BE3 I decrease (no change) 0.48 M f increase NH3 I decrease (no change) 0.55 M f increase A BF,NH3 f increase I decrease (no change) 1.01 M 0.41 M f increase I decrease (no change) BF, NH3 I decrease (no change) 0.48 M f increase В BF,NH3 f increase I decrease (no change) 1.08 M BF3 I decrease (no change) 1.07 M ↑ increase NH3 I decrease (no change) 1.14 M f increase C…
