Answer 2

Let's go through each chemical equation one by one:

1. CuSO4 + KNO3: This reaction does not produce a single compound. CuSO4 (copper(II) sulfate) and KNO3 (potassium nitrate) are both ionic compounds and can undergo a double replacement reaction. The general equation for a double replacement reaction is:

AB + CD → AD + CB

In this case, CuSO4 (AB) and KNO3 (CD) would react to form Cu(NO3)2 (AD) and K2SO4 (CB). The balanced chemical equation for this reaction would be:

CuSO4 + 2KNO3 → Cu(NO3)2 + K2SO4

2. CuSO4 + BaCl2: Similarly, this reaction is also a double replacement reaction. CuSO4 (copper(II) sulfate) and BaCl2 (barium chloride) can react to form CuCl2 (copper(II) chloride) and BaSO4 (barium sulfate). The balanced equation is:

CuSO4 + BaCl2 → CuCl2 + BaSO4

3. CuSO4 + H2SO4: This reaction involves a strong acid and a salt. CuSO4 (copper(II) sulfate) can react with H2SO4 (sulfuric acid) to produce a new compound and release sulfur dioxide (SO2) gas. The balanced equation is:

CuSO4 + H2SO4 → Cu(HSO4)2 + SO2↑

In this reaction, Cu(HSO4)2 represents a copper(II) hydrogen sulfate complex.

It's important to note that these equations assume the reactions occur under suitable conditions, such as appropriate temperature and pressure, and that the reactants are present in stoichiometric quantities.
