Answer 2

3Cu+8HNO₃= 3Cu(NO₃)₂+2NO+4H₂O

S+2H₂SO₄=3SO₂+2H₂O

Answer 3

To balance the chemical equations, we need to make sure that the same number of each type of atom is present on both sides of the equation. Let's start by balancing the given chemical equations:

1. Cu + HNO3 -> Cu(NO3)2 + NO + H2O

Balancing the equation: Cu + 4HNO3 -> Cu(NO3)2 + 2NO + 2H2O

2. CuS + H2SO4 -> SO2 + H2O

Balancing the equation: CuS + 2H2SO4 -> SO2 + H2O + CuSO4

The balanced chemical equations are as follows:

1. Cu + 4HNO3 -> Cu(NO3)2 + 2NO + 2H2O
2. CuS + 2H2SO4 -> SO2 + H2O + CuSO4

Please note that the coefficients in the balanced equations represent the stoichiometric ratios of the reactants and products.
