When a solid calcium carbonate was reacted with hydrochloric acid, it produced a gas and calcium chloride salt in aqueous solution. a. Write a balanced equation for this reaction. b. How many moles of calcium carbonate is needed for 15.0 mL hydrochloric acid? The density of the acid is 1.18 g/mL. c. If we dissolve 3.29 g calcium carbonate to make a solution with 500 mL volume, what is the concentration (M) of the solution? d. How much is the concentration from (c.) in ppb? e. Write an equilibrium constant expression for this reaction. f. Calculate for the K value when the concentration of the product/s is 1.24 x 10-3 M and the reactant/s is 2.05 x 10-4 M. Where will the direction of the equilibrium go to?
