According to the ideal gas law (PV = nRT), at the same temperature (T) and in the same volume (V), the pressure (P) of a gas is directly proportional to the number of moles (n) of that gas. Since 1 mole of hydrogen gas is present compared to 0.5 moles of oxygen gas in equal volumes, the pressure of the hydrogen gas will be twice that of the oxygen gas. Therefore, the pressures of the gases are not equal.
Liquid water can be separated into hydrogen gas and oxygen gas through electrolysis. 1
mole of hydrogen gas and 0.5 moles of oxygen gas are produced from 1
mole of liquid water and are collected into separate containers of the same volume at the same temperature. Are the pressures of the gases equal? In one to two sentences, use the ideal gas law to explain your answer
