Need help with balancing net ionic equations and molecular equation?

What is the molecular equation for the reaction of calcium carbonate with nitric acid? CaCO3 + HNO3 --> H2O + CO2 + Ca(NO3)2 Would this be correct? What is the ionic equation for the reaction of calcium carbonate with sulfuric acid? CaCO3 + H2SO4 --> ??? This means that I dont have to remove... show more What is the molecular equation for the reaction of calcium carbonate with nitric acid?
CaCO3 + HNO3 --> H2O + CO2 + Ca(NO3)2
Would this be correct?
What is the ionic equation for the reaction of calcium carbonate with sulfuric acid?
CaCO3 + H2SO4 --> ???
This means that I dont have to remove spectator ions?
What is the ionic equation for the reaction of iron (II) sulfide with hydrogen bromide?
FeS + HBr -->
Same as above...
What is the net ionic equation for the reaction of tin chloride (II) with potassium hydroxide?
KOH + SnCl2 -->
This time I remove spectator ions?

Answers with Explanations would be really helpful, btw do any of these have to be balanced? Physical states would really help too
Thank you
