Question

Balance the following chemical reactions:

Answer 1

1. I think is good answer

Answer 2

1. 2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂

2. CH₄ + 2O₂ → CO₂ + 2H₂O

3. Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag

4. MnO₂ + 4HCl → MnCl₂ + 2H₂O + Cl₂

5. Pb(NO₃)₂ + 2NaCl → PbCl₂ + 2NaNO₃

1)

$NaCl+AgNO_3=>NaNO_3+AgC\downarrow$

2)

CuSO_4+Cu_2Cl_2\neq>

$CuSO_4+Cu_2l_2\neq$
