Balance the Following Equations: Instruction: While balancing equation write the physical state of reactants and products as well as any reaction conditions. Write in steps

1) CuSO4 + KI →Cu2I2 + K2SO4 + I2

2) NH3 + O2 →NO + H2O

3)Fe2O3 + CO → Fe + CO2

4) Cu + AgNO3 → Cu(NO3)2 + Ag

5) Pb(NO3)2 + H2SO4 → PbSO4 + HNO3

6) CaCO3 + HCl → CaCl2 + H2O(l) + CO2

7)MnO2 + HCl → MnCl2 + H2O + Cl2​
