One mole of water is placed in a 100-liter container and heated to 143

1.	One mole of water is placed in a 100-liter container and heated to 14320C.The kc for the reaction 2H2O(g) ⇄ 2H2(g) + O2(g) is 1.35x10-11.Determine the following:a. concentration of hydrogenb. concentration of oxygen
Answer» Answer:A)Hydrogen ion concentration is more conveniently expressed as pH, which is the LOGARITHM of the RECIPROCAL of the hydrogen ion concentration in gram moles per liter. THUS, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral. 2)The ATMOSPHERIC concentration of O2 has remained constant for several HUNDRED years at 20.95%. This means that exactly 20.95% of the molecules in the atmosphere are O2 molecules. Explanation:
