Like most alkali metals, potassium reacts with water to form basic potassium hydroxide and hydrogen gas: 2K + 2H20 2KOH + H2
How much hydrogen gas will be formed by reacting 125 g potassium?

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
