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)

A typical person has an average heart rate of 69.0 beats/min. Calculate the given questions. How many beats does she have in 7.0
Molodets [167]

Answer:

See explanation

Explanation:

Average heart beat = Number of heart beats/ time

7.0 years = 7.0 * 365 * 24 * 60 = 3679200 minutes

If there are 69 beats in 1 minutes

There are x beats in 3679200 minutes

x = 253865 beats

x = 254000.00 beats ( to 3 sf)

beats in 7.00 years = 254000.000 beats

beats in 7.000 years = 254000.0000 beats
