2HCI(ag) + CaCO3(s) ? CaCl2(s) + CO 2(g) +H2O(1) From the reaction above, which of the curves in the diagram represents the production of carbon (IV) oxide ...

Answer Details

The given chemical equation shows the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) to produce calcium chloride (CaCl2), carbon dioxide (CO2), and water (H2O). The production of carbon dioxide gas is represented by the curve that shows an increase in gas volume or pressure as the reaction proceeds. As dilute HCl is added to the mixture, it reacts with the solid CaCO3 to release CO2 gas. The gas is then collected in the container, causing the volume or pressure of the gas to increase over time. The curve that represents this increase in gas volume or pressure is curve M. Therefore, the correct answer is M.
