Question

Which of the following equations is balanced?

• A. \( \text{Mg} + \text{O}_2 \rightarrow \text{MgO} \)
• B. \( \text{Zn} + \text{H}_2\text{SO}_4 \rightarrow \text{ZnSO}_4 + \text{H}_2 \)
• C. \( \text{Fe} + \text{Cl}_2 \rightarrow \text{FeCl}_3 \)
• D. \( \text{H}_2 + \text{Cl}_2 \rightarrow \text{HCl} \)

Hint:

Always check if the number of atoms of each element is the same on both sides of the equation for it to be balanced.

Answer 1

The Correct Option is D

The equation \( \text{H}_2 + \text{Cl}_2 \rightarrow \text{HCl} \) is balanced as both sides contain the same number of hydrogen and chlorine atoms.
