1. Would the following errors increase, decrease, or have no effect on the calculated moles of gas collected in the experiment? Explain your answers in complete sentences.
a. The measured mass of the magnesium was smaller than the true mass.
b. The actual temperature of the hydrogen gas is lower than room temperature.
2. Explain in terms of particle collisions and Dalton’s law why it can be assumed that the total pressure inside the gas collection tube is equal to the atmospheric pressure outside of the tube.
