Determine which of the following equations is not balanced correctly. Mg(s) + 2H2O(l) → Mg(OH)2(aq) + H2(g)N2(g) + 3H2(g) ⇌ 2NH3(g) C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l) Fe2O3(s) + 2C(s) → 3Fe(s) + 2CO2(g)
Question
Determine which of the following equations is not balanced correctly. Mg(s) + 2H2O(l) → Mg(OH)2(aq) + H2(g)N2(g) + 3H2(g) ⇌ 2NH3(g) C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l) Fe2O3(s) + 2C(s) → 3Fe(s) + 2CO2(g)
Solution
The equation that is not balanced correctly is Fe2O3(s) + 2C(s) → 3Fe(s) + 2CO2(g).
Here's why:
-
Mg(s) + 2H2O(l) → Mg(OH)2(aq) + H2(g): This equation is balanced. There is 1 Mg, 2 H, and 2 O on both sides.
-
N2(g) + 3H2(g) ⇌ 2NH3(g): This equation is balanced. There are 2 N and 6 H on both sides.
-
C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l): This equation is balanced. There are 6 C, 12 H, and 18 O on both sides.
-
Fe2O3(s) + 2C(s) → 3Fe(s) + 2CO2(g): This equation is not balanced. There are 2 Fe, 3 O, and 2 C on the left side, but 3 Fe, 4 O, and 2 C on the right side. The number of oxygen atoms is not the same on both sides, so this equation is not balanced.
