A mixture of 2.0 mol of H2(g) and 1.0 mol of O2(g) is placed in a sealed evacuated container made of a perfect insulating material at 24 ∘C. The mixture is ignited with a spark and it reacts to form liquid water. (The specific heat for water vapor is 2.04 J/g⋅oC, and ∆Hvap = 44.0 kJ/mol) The heat generates in the exothermic reaction will heat the liquid water to boiling, vaporize it, and heat the vapor to its final temperature....

A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5427 atm when placed in a sealed container. The complete combustion of the mixture to carbon dioxide gas, CO2(g), and water vapor, H2O(g), was achieved by adding exactly enough oxygen gas, O2(g), to the container. The pressure of the product mixture in the sealed container is 2.417 atm. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume remain constant.
Liquid water can be split into hydrogen gas and oxygen gas (ΔH = 285.8 kJ/mol) by applying energy through an electric current
Liquid water can be split into hydrogen gas and oxygen gas (ΔH = 285.8 kJ/mol) by applying energy through an electric current. In this experiment, 13.31 kJ of energy are applied to 12.3 grams of water in a sealed reaction vessel whose volume is 4.56 L and whose temperature is 311.15 K Note: At 311.15 K, the vapor pressure of water is 0.0654 atm. (a) Is this reaction exothermic or endothermic? (b) Write a balanced chemical equation for this reaction. Be sure to...
