Question
what will be the product fromed when zinc reacts with sulphuric acid write the balance chemical equation for this reaction
Solution
When zinc reacts with sulphuric acid, the products formed are zinc sulphate and hydrogen gas.
The balanced chemical equation for this reaction is:
Zn(s) + H2SO4(aq) -> ZnSO4(aq) + H2(g)
Here's the step by step process:
- Zinc (Zn) reacts with Sulphuric acid (H2SO4).
- This reaction is a displacement reaction where Zinc displaces Hydrogen from the Sulphuric acid.
- The products formed are Zinc Sulphate (ZnSO4) and Hydrogen gas (H2).
- The balanced chemical equation is written by ensuring the number of atoms for each element is the same on both the reactant and product side.
