Final answer:
The balanced chemical equation for the reaction between aqueous strontium sulfide (SrS) and aqueous copper(II) nitrate (Cu(NO3)2) is SrS(aq) + Cu(NO3)2(aq) → Sr(NO3)2(aq) + CuS(s), where strontium nitrate remains in solution and copper(II) sulfide forms a precipitate.
Step-by-step explanation:
The question asks for the balanced chemical equation between aqueous strontium sulfide and aqueous copper(II) nitrate. The chemical formula for strontium sulfide is SrS and for copper(II) nitrate it is Cu(NO3)2. When these two react, a double displacement reaction occurs, forming strontium nitrate (Sr(NO3)2) and copper(II) sulfide (CuS), which is a precipitate.
The balanced equation is as follows:
SrS(aq) + Cu(NO3)2(aq) → Sr(NO3)2(aq) + CuS(s)
Here, we do not need to adjust coefficients because the stoichiometry requires one mole of each reactant to form one mole of each product. Note that in writing a balanced chemical equation, it is important to ensure that the number of atoms of each type is the same on both sides of the equation, which is true in this case.
