Another Chem question (Best Answer will obviously be chosen)?

Pennies in the United States now consist of a zinc disk that is coated with a thin layer of copper. If a penny is scratched and then soaked in sulfuric acid, it is possible to dissolve the zinc disk, leaving only a thin hollow shell of copper.Write the unbalanced chemical equation to illustrate the reaction of zinc metal with sulfuric acid, which produces dissolved zinc sulfate and evolves gaseous hydrogen. (Include states-of-matter under SATP conditions in your answer.)
