Error Analysis Questions:
1. Assuming the magnesium ribbon wasn't sufficiently polished toremove a coating of magnesium oxie on the surface. How would thisaffect the volume of hydrogen gas produced? Would this error causethe gas constant to be overestimated, underestimated, or remainunaffected? Please explain your reasoning.
2. Assume the water doesn't properly drain from the eudiometertube therby leaving droplets on the sides of the glass. Would thiserror cause the gas constant to be overestimated, underestimated,or remain unaffected? Please explain your reasoning.
3. Imagine that as the magnesium reacts with the hydrochloricacid, a small portion of the hydrogen gas generated dissolves inthe water. How would this affect the volume of H2 gas measured inthe eudiometer tube? Would this error cause the gas constant to beoverestimated, underestimated, or remain unaffected? Please explainyour reasoning.
4. If the temperature of the hydrogen gas was underestimated,would this error cause the gas constant to be overestimated,underestimated, or remain unaffected? Please explain yourreasoning.
