A student adds excess large pieces of magnesium carbonate, $$\(\mathrm{MgCO}_{3}\)$$, to dilute hydrochloric acid, $$\(\mathrm{HCl}\)$$, and measures the volume of carbon dioxide gas, $$\(\mathrm{CO}_{2}\)$$, given off. The graph shows how the volume of carbon dioxide gas changes with time. The student repeats the experiment using powdered $$\(\mathrm{MgCO}_{3}\)$$ instead of large pieces. All other conditions stay the same. On the grid, draw the line expected when powdered $$\(\mathrm{MgCO}_{3}\)$$ is used instead of large pieces.
