Skill Area P : Planning experimental procedures: Information: Word equation: Hydrochloric acid (s) + Calcium carbonate (aq) ==> Carbon dioxide (g) + Calcium Chloride (aq) + Water (l) Chemical equation: 2HCl (s) + CaCO3 (aq) ==> CO2 (g) + CaCl2 (aq) + H2O (l) Ratio: 2 : 1 ==> 1 : 1 : 1 Molar ratio in thousandths: 0.002 : 0.001 ==> 0.001 : 0.001 : 0.001 The above equation shows when two moles of hydrochloric acid are added to one mole of calcium carbonate the products made are one mole of carbon dioxide, one mole of calcium chloride and one mole of water. Introduction: In a chemical reaction, the starting materials are called the reactants, and the finishing materials are called the products. If the reactants take a short time to change into products the reaction is a fast reaction. If the reaction takes a long time to change into the products the reaction is...
