liquid disilicon hexachloride reacts with water to form solid silicon dioxide, hydrogen chloride gas, and hydrogen gas. be sure
kodGreya [7K]

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

Si{2}Cl{6} (l)  +  4H{2}O (l)  ------ > 2SiO{2} (s)  +    6HCl (g)    +      H{2} (g)

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

Si{2}Cl{6} (l)  +  H{2}O (l)  ------ > SiO{2} (s)  +    HCl (g)    +      H{2} (g)

now , we have to balance the eqaution,

                   Reactants            product

Si                      2                          1

Cl                      6                          1

H                      2                           3

O                      1                            2

Multiply 4 with H{2}O  2 with  SiO{2}  and 6 with HCL, we get

Si{2}Cl{6} (l)  +  4H{2}O (l)  ------ > 2SiO{2} (s)  +    6HCl (g)    +      H{2} (g)

now ,

                  Reactant       Product

Si                     2                   2

Cl                     6                   6

H                      8                   8

O                    4                     4

Thus, we get the desire equtions.

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

Si{2}Cl{6} (l)  +  4H{2}O (l)  ------ > 2SiO{2} (s)  +    6HCl (g)    +      H{2} (g)
