Question

Can someone write a word equation and skeleton equation for these, please?

Calcium hydrogen carbonate reacts with hydrobromic acid to produce calcium bromide, water, and carbon dioxide.
During combustion, benzene (C6H6) and oxygen gas react to produce carbon dioxide and water.
At high temperatures, a reaction between silicon tetrachloride and silicon produces disilicon hydrochloride.
a. Ca(HCO3)2 + 2HBr → CaBr2 + 2H2O + 2CO2
b. C6H6 + 9O2 → 6CO2 + 3H2O
c. SiCl4 + 2Si → Si2Cl6
d. CaHCO3 + HBr → CaBr + H2O + CO2

Answer 1

The word equation for the first reaction is: Calcium hydrogen carbonate + Hydrobromic acid → Calcium bromide + Water + Carbon dioxide. The skeleton equation for the first reaction is: Ca(HCO3)2 + 2HBr → CaBr2 + 2H2O + 2CO2. The word equation for the second reaction is: Benzene + Oxygen gas → Carbon dioxide + Water. The skeleton equation for the second reaction is: C6H6 + 9O2 → 6CO2 + 3H2O. The word equation for the third reaction is: Silicon tetrachloride + Silicon → Disilicon hydrochloride. The skeleton equation for the third reaction is: SiCl4 + 2Si → Si2Cl6.

Step-by-step explanation:

The word equation for the first reaction is: Calcium hydrogen carbonate + Hydrobromic acid → Calcium bromide + Water + Carbon dioxide

The skeleton equation for the first reaction is: Ca(HCO3)2 + 2HBr → CaBr2 + 2H2O + 2CO2

The word equation for the second reaction is: Benzene + Oxygen gas → Carbon dioxide + Water

The skeleton equation for the second reaction is: C6H6 + 9O2 → 6CO2 + 3H2O

The word equation for the third reaction is: Silicon tetrachloride + Silicon → Disilicon hydrochloride

The skeleton equation for the third reaction is: SiCl4 + 2Si → Si2Cl6
