Question

State the information conveyed by the following equation. $Z n (s) + 2 H C l (a q) \to Z n C l_{2} (a q) + H_{2} ↑$

Open in App

Solution

Information from the equation :

Zn reacts with HCl. So, these are the reactants.

Zn displaces hydrogen in HCl. Zinc chloride and hydrogen gas are formed.

So, these are the products.

1 molecule of Zn reacts with 2 molecules of HCl to form 1 molecule of $Z n C l_{2}$ and 1 molecule of $H_{2}$ .
