What is the symbol equation for Zinc + Sulphuric acid

Jun 24, 2008 · In sulfuric acid, 2 atoms of hydrogen, each with an oxidation number of +1 offsets sulfate's oxidation number of2. On the product side of the equation, Hydrogen is a diatomic molecule (must always appear in 2's) so H2 if correct. In zinc sulfate, zinc has an oxidation number of +2 and sulfate is2 so they balance as is written.
