2CO + O2 --> 2CO2
It is already balanced, you have the same number of H's and the same number of Cl's in each side of the equation.
MgCl2
The chemical equation is:SF4 + 2 H2O = SO2 + 4 HF
This simple equation is: 2H2 + O2 = 2H2O
1,3,1,3
liho+h2s=
2Na + CaCl2 = 2NaCl + Ca. Just make sure same number of elements are on both sides.
Cs2 + 3o2 ------->>> co2 + 2so2
2Na + 2H2O -> H2 + 2NaOH
4P + 5O2 = 2P2O5
Na2SO3 + 2HCl -> 2NaCl + H2SO3
2c + o2---2co
