Verified step by step guidance
1
insert step 1> Identify the type of reaction for each given pair of reactants.
insert step 2> For part (a), recognize that both H2SO4 and HNO3 are strong acids and typically do not react with each other in aqueous solution, so write 'NO REACTION.'
insert step 3> For part (b), recognize that this is a double displacement reaction involving aqueous strontium sulfide (SrS) and aqueous copper(II) sulfate (CuSO4).
insert step 4> Write the potential products of the double displacement reaction: strontium sulfate (SrSO4) and copper(II) sulfide (CuS).
insert step 5> Balance the molecular equation: SrS(aq) + CuSO4(aq) -> SrSO4(s) + CuS(s).
