As an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a “burp”). Write the unbalanced chemical equation for this process.arrow_forward

Use your equation to help answer the following questions. a Write, in words, a description of the reaction on the particulate level. b If you were to build physical ball-and-stick models of the reactants and products, what minimum number of balls representing atoms of each element do you need if you show both reactants and products at the same time? c What if the models of the reactants from Part b were built and then rearranged to form products? How many balls would you need? d Use words to interpret the equation on the molar level. e Use the molar-level interpretation of the equation from Part d and molar masses rounded to the nearest gram to show that mass is indeed conserved in this reaction.arrow_forward
