2 PbO + C -> 2 Pb + CO2
I would think -5 plus 5 equals 0.
That would be 90.
2Na + 2H2O -> H2 + 2NaOH
To balance the reaction between NaOH and H2SO4, you first write out the unbalanced equation: NaOH + H2SO4 -> Na2SO4 + H2O. To balance it, you need to ensure the same number of atoms of each element on both sides of the equation by adjusting the coefficients. In this case, you would need to put a coefficient of 2 in front of NaOH to balance the equation: 2NaOH + H2SO4 -> Na2SO4 + 2H2O.
2Na + 2H2O -------> 2NaOH + H2
The balanced equation for Na2O + H2O → 2 NaOH is: Na2O + H2O → 2 NaOH
It is already balanced
The balance is 2N2 +2O2= 4NO
The chemical reaction is:H3PO4 + 3 NaOH + Na3PO4 + 3 H2O
This equation is HCl + NaOH -> NaCl + H2O.

2 Mg + 2 NaOH-------2 MgO + H2 + 2 Na 2 Al + 6 NaOH------2 Na3AlO3 + 3 H2
To balance the chemical equation ZnS + O2 = ZnO + SO2, you need to make sure that the number of each type of atom is the same on both sides of the equation. Start by adding coefficients to the compounds; in this case, a coefficient of 2 in front of ZnS and SO2 balances the equation: 2 ZnS + 3 O2 = 2 ZnO + 2 SO2.
