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.)
