chemistry
if you added sulfuric acid to calcium nitrate what products in addition to calcium sulphate would you get if any ? if you start with calcium nitrate mixed into H2SO4 (aq), wouldn't you get a solution of nitric acid? H2SO4 + Ca(NO3)2 >>> 2 HNO3(aq) + CaSO4(s)

chemistry
write a balanced chemical equation for calcium nitate plus sulfuric acid produces calcium sulphate and ? This is a metathetical reaction, I think more properly called a double displacement reaction now. Just change + and - partners. Ca(NO3)2 + H2SO4 ==> CaSO4 + HNO3. I will...
