cl₂ + h₂ → 2hcl\nin the reaction above, the coefficient of cl₂ is \nthe subscript of cl₂ is
Answer
Answer:
- 2
Explanation:
Step1: Identify coefficient
The number in front of a chemical - species in a balanced chemical equation is the coefficient. For $\mathrm{Cl}{2}$ in $\mathrm{Cl}{2}+\mathrm{H}_{2}\rightarrow2\mathrm{HCl}$, there is no number written explicitly, which means the coefficient is 1.
Step2: Identify subscript
The subscript is the number written at the bottom right of the symbol of an element in a chemical formula. For $\mathrm{Cl}_{2}$, the subscript of $\mathrm{Cl}$ is 2, indicating there are 2 chlorine atoms in one molecule of chlorine gas.
