Question

Magnesium will react with the strong acid HCl to produce magnesium chloride and hydrogen gas according to the following reaction: Mg (s) + HCl (aq) ? MgCl2 (aq) + H2 (g) Your task is to analyze the data taken from several experiments of the above reaction. Trial | Mass of Mg (g) | Volume of HCL (mL) | Volume of H2 gas (mL) 1 | 0.020 | 10.0 | 21 2 | 0.040 | 10.0 | 42 3 | 0.080 | 10.0 | 82 4 | 0.120 | 10.0 | 122 5 | 0.160 | 10.0 | 122 6 | 0.200 | 10.0 | 122 Here are some suggestions of topics on which to elaborate upon in your explanations: • Define limiting reagent and explain how to identify it. • An explanation of the relationship between the limiting reagent and theoretical yield. • Provide an explanation of how to determine the molar ratio from a chemical equation. • Provide insight into how we use our senses to make scientific observations.
