Assume you are in a lab with a test tube of sulfuric acid. You drop a piece of calcium into the tube. What do you observe happening in the tube?
Is this something you did? Something you will be doing? Ca is a reactive metal. It will react with water to produce hydrogen gas. It will react with sulfuric acid even faster and more violently. In fact, it may produce so much heat that the hydrogen gas will explode spattering H2SO4 everywhere. H2SO4 is not something (especially when it is hot) you want on you or your neighbors. My recommendation is that you not do this. I hope this is just a paper exercise.
