Answer:
SiCl4 + H2O = SiO2 + HCl
Reactant. product
Si = 1 atom Si = 1 atom
Cl = 4 atom Cl = 1 atom
H = 2 atom H = 1 atom
O = 1 atom O = 2 atom
SiCl4. + 2H2o = SiO2 + 4hcl
Reactant. product
Si = 1 atom Si = 1 atom
Cl = 4 atom Cl = 4 atom
H = 4 atom H = 4 atom
O = 2 atom O = 2 atom
Balanced chemical equation.
