Question

Balance the following equations :
(i) CH4(g) + O2(g) + CO2(g) + H2O(g)
(ii) Als) + HCl(aq) → AlCl3(aq) + H2(g)​

Answer 1

Explanation:

(i) CH4(g) +2O2(g)→ CO2(g) +2H2O

(ii) 2Al(s)+2HCl(aq)→ 2AlCl3(aq)+H2

Answer 2

(i) CH4 + O2 → CO2 + H20

❤ ${CH}_{4} \: {+} \: {2O}_{2} \: {~→~} \: {CH}_{2} \: {+} \: {2H}_{2}{O}$

(ii) Al + HCl → AlCl3 + H2

❤ ${2Al} \: {+} \: {2HCl} \: {~→~} \: {2AlCl}_{3} \: {+} \: {3H}_{2}$
