a) Consider the production of chlorine using the following reaction: 4NH3(g) + 5O2(g) = 4NO(g) + 6H₂O(g) AH = -906 kJ mol-¹ When 0.45 mol of NH3, 0.20 mol of O2 and 0.10 mol of NO were initially mixed in a 5.0 L vessel and the mixture allowed to attain equilibrium, it was found that 0.20 mol of NO was present at equilibrium at 10 minutes. The temperature was kept constant. i. Define equilibrium. ii. Write the equilibrium expression, Kc. iii. Calculate the number of moles of each species present at equilibrium by constructing an ICE table. Show your working. iv. Calculate the value of Kc for this reaction.

Therefore, a 100-g sample of water contains 11.2 g of hydrogen atoms and 88.8 g of oxygen atoms. A hydrocarbon is a compound that contains mostly carbon and hydrogen. Calculate the percent composition (by mass) of the following hydrocarbon: CH22 Enter the percentages of carbon and hydrogen numerically to four significant figures, separated by commas.
