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 is concentrated acid but (aq) if it is in water solution. Same for HNO3. (s) for Ca(NO3)2 if it is a solid, (aq) if it is a solution, UNLESS your instructor wants you to show ions present.
