Question

5. Balance the following chemical equations :
(a) FeS + 2HCl → FeCl2 + H S
(b) Na CO2 + 2HCl → 2NaCl + H,O + CO2
(c) 2H, +0, → 2H,0
(d) Na,O + H,0 + 2NaOH
q​

Answer 1

2naoh +h2 = 2na+ water

my ans

Answer 2

Answer:

FeS + 2HCl → FeCl2 + H2S

Na2CO3(aq)+2HCl(aq)→2NaCl(aq)+CO2(g)+H2O(l)

2H2OΔ→2H2+O2.

Na2O + H2O → 2 NaOH
