Question

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. (2 points)

Explanation:

According to the ideal gas law $PV = nRT$. Since $V$, $T$, and $R$ are the same for both gases but the number of moles ($n$) of hydrogen and oxygen are different ($n_{H_2}=1$, $n_{O_2}=0.5$), the pressures will not be equal.

Answer:

No, the pressures are not equal because the number of moles of the two gases are different while volume, temperature and the gas - constant are the same.
