Gases produced by a chemical reaction can easily be collected over water. To determine the pressure of the dry gas, the vapor pressure of
he water at that temperature must be subtracted from the total pressure.
1) Consider the following reaction:
Mg(s) + 2 HCl(aq) →→→ MgCl₂(aq) + H₂(g)
The total pressure of gas collected over water 680.0 mmHg and the temperature is 25.5°C What is the pressure of hydrogen gas formed in mmHg?

A student experimentally determines the gas law constant, R, by reacting a small piece of
magnesium with excess hydrochloric acid and then collecting the hydrogen gas over water

beaker at the end of the reaction. The water level in the eudiometer is 1-inch
above the water level in the beaker.

The student notices a large air bubble in the eudiometer after collecting the
hydrogen gas, but does not dislodge it.
Sulfur dioxide reacts with oxygen in the presence of plati-
num to give sulfur trioxide:
2 SO2(g) + O2(g) → 2 SO3(g)
Suppose that at one stage in the reaction, 26.0 mol SO2,
83.0 mol O2, and 17.0 mol SO3 are present in the reaction
