Question : 7 of 10

Marks: +1, -0

Complete the following chemical equations:
(i)

{\C}_2 {\H}_5 {\OH}+ {\O}_2 →

(ii)

{\C}_2 {\H}_5 {\OH} \;{{ {───────────▶}↖{\;\text " Conc. "\; {\H}_2 {\SO}_4}}}↙{{443 {\K}}}

Solution:

(i)

{\C}_2 {\H}_5 {\OH}+3 {\O}_2 {→}↖{∆} 2 {\CO}_2+3 {\H}_2 {\O}

+ Energy
(ii)

{\C}_2 {\H}_5 {\OH} {───────▶}↙{443 {\K}}↖↖{\;\text " Conc. "\; {\H}_2 {\SO}_4 .} {\CH}_2= {\CH}_2+ {\H}_2 {\O}

(iii)

{\CH}_3 {\COOH}+ {\NaHCO}_3 → {\CH}_3 {\COONa} + {\H}_2 {\O}+ {\CO}_2 ↑
