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)

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...

Given a solution in moles per litre how would you convert to parts per million)ppm.) could you help,no other information given apart from solution contains a known concentation of aluminium mols/L. Convert mols to grams. That will be grams per 1000 mL. Convert that to mg/L. ...

calcium nitrate + sulfuric acid =caso4+? write a balanced chemical equation for this reaction including states. Ca(NO3)2 + H2SO4 ==> CaSO4 + 2HNO3 You don't have enough information to provide states. CaSO4 will be a solid so you write CaSO4(s). H2SO4 will be (l) if it ...
