Compounds at the Pharmacy

A few days ago, Richard went back to the pharmacy to pick up aspirin,

He also wanted to talk to Sarah about a way to treat his sore toe. Sarah recommended soaking his foot in a solution of Epsom salts, which is magnesium sulfate. Richard also asked Sarah to recommend an antacid for his upset stomach and an iron supplement. Sarah suggested an antacid that contains calcium carbonate and aluminum hydroxide, and iron(II) sulfate as an iron supplement. Richard also picked up toothpaste containing tin(II) fluoride, and carbonated water, which contains carbon dioxide.

Write the chemical formula for each of the following:

a. calcium carbonate

b. carbon dioxide

c. iron(II) sulfate
