SiCl4+2H3O2= H4SiO4+ 2HCl2 The four next to Cl, the three next to H, the two next to O and every other number to the right of the element should be a small number written on the right bottom corner of the element.... Hope this helps
it does
Ca2Si + 4Cl2 >> 2CaCl2 + SiCl4
2ZnS + 3O2 = 2ZnO + 2SO2
BaCl2 + K2SO4 --> BaSO4 + 2KCl
2 NaHCO3 = Na2CO3 + CO2 + H2O.
Four ammonia plus five oxygen molecules yields 4 nitrous oxide plus six water.
You don't
Ca2Si + 4Cl2 >> 2CaCl2 + SiCl4
The balance is 2N2 +2O2= 4NO
2h2s + so2 ----------> 3s + 2h2o
Already balanced
Fe2O3 + H2SO4
liho+h2s=
cl2o7+h2o
C3h8 + 5o2 -> 3co2 + 4h2o
2ZnS + 3O2 = 2ZnO + 2SO2
BaCl2 + K2SO4 --> BaSO4 + 2KCl
4Li + O2 -> 2Li2O
