CBSE Class 10 Science 2017 Delhi Term II Set 2 Paper

Question : 5 of 9

Marks: +1, -0

Complete the following chemical equations:
(i)

{\CH}_3 {\COOH}+ {\Na}_2 {\CO}_3 →

(ii)

{\CH}_4+ {\O}_2 →

(iii)

2 {\C}_2 {\H}_5 {\OH}+ {\Na} →

Solution:

(i)

2 {\CH}_3 {\COOH}+ {\Na}_2 {\CO}_3 → 2 {\CH}_3 {\COONa}+ {\H}_2 {\O}+ {\CO}_2 ↑

(ii)

{\CH}_4+2 {\O}_2 {→}↖{∆} {\CO}_2 ↑+2 {\H}_2 {\O}

(iii)

2 {\C}_2 {\H}_5 {\OH}+2 {\Na} → 2 {\C}_2 {\H}_5 {\ONa}+ {\H}_2 ↑
