Question

1. Fe + CuCl₂ = FeCl₂ + H₂ 2. S + O₂ = SO3 3. Mg(NO3)2 4. NH3 = N₂ + H₂ 5. AgNO3 = Ag NO2+ O₂ MgO + NO₂ + O₂​

Answer 1

It seems like you've listed some chemical equations. I can help you balance these equations. Here are the balanced equations:

1. Fe + 2CuCl₂ = 2FeCl₂ + Cu
2. 2S + 3O₂ = 2SO₃
3. Mg(NO₃)₂ = MgO + 2NO₂ + 1/2O₂
4. 4NH₃ = N₂ + 6H₂
5. 2AgNO₃ = 2Ag + NO₂ + O₂

Please note that equation 3 appears to be a decomposition reaction, and the coefficients for NO₂ and O₂ are not whole numbers. Balancing such equations may involve fractions.
