Jane wants to make an acid. She has two possible compounds she could add to 250.0 g of water to make this acid - EITHER 234.5 g of calcium oxide OR 678.9 g of tetraphosphorus decaoxide (she won't use both, just one).
a. Which compound should she use? Explain your answer (with words and full sentences), and write any balanced chemical reactions that would help you justify your claim.
b. What is the chemical formula of the acid, and what is the maximum mass of the acid she could theoretically produce when she does this reaction?
c. What is the EXCESS reactant, and how many grams of this reactant are leftover when the reaction is completed?
