Balance each of the following chemical equations: a. N2(g) + O2(g) → NO(g)
b. HgO(s) = Hg(l) + O2(8)
c. Fe(s) + O2(g) →→ Fe2O3(s)
d. Na(s) + Cl2(g) →→ NaCl(s)
e. Cu2O(s) + O2(g)
→ CuO(s)

a. N₂(g) + O₂(g) → 2 NO(g)

b. 2 HgO(s) → 2 Hg(l) + O₂(g)

c. 4 Fe(s) + 3 O₂(g) → 2 Fe₂O₃(s)

d. 2 Na(s) + Cl2(g) → 2 NaCl(s)

e. 2 Cu₂O(s) + O₂(g)  → 4 CuO(s)

Hope this helps.

i need mutiple choices
