Brass is an alloy of copper and zinc.When ground into a fine powder,then added to hydrochloric acid solution,a single replacement reaction occurs with one of the metals.A soluble salt and hydrogen gas are produced.

A)The balnce equation for the reaction that occurs?
B)If a 60.0 g sample of the alloy contained enough of the metal to produced 75.2 g of it's salts,determine the percentage composition of the alloy?
Assume all the metal is converted to the salt.
