The purpose of the following investigation is to determine the percentage yield of a reaction that involves gases.

Experimental design

A known mass of calcium carbonate reacts with hydrochloride acid the carbon dioxide produced is captured by the downward displacement of water, and the temperature, pressure and volume of the gas are measured. Assume that the carbon dioxide does not dissolve in the water

Observations

Masa of calcium carbonate =3.02g

Atmospheric pressure =98.5kpa

Volume=748ml

Ambient temperature =23.0-degree Celsius

Analysis

a. Write out the word equation and a balanced reaction

b. What is the volume of carbon dioxide produced
