Hydrogen peroxide can be produced in the lab by reacting barium peroxide with hydrochloric acid. another product of the reaction is barium chloride.

Question

1). what is the balanced chemical equation for the reaction?

2). what mass of hydrogen peroxide should result when 1.50g of barium peroxide is reacted with 25.0 mL of 0.50 M hydrochloric acid?

Answer 1

Here is a link that shows you how to solve all of your "simple" stoichiometry problems. It won't do limiting reagent problems without modification.
