The liquid disilicon hexachloride reacts with water to form solid silicon dioxide, hydrogen chloride gas and hydrogen gas are

When liquid disilicon hexachloride reacts with water to form solid silicon dioxide , hydrogen chloride gas and hydrogen gas , the following chemical equation is:

now , we have to balance the eqaution,
Reactants product
Si 2 1
Cl 6 1
H 2 3
O 1 2
Multiply 4 with
2 with
and 6 with HCL, we get

now ,
