Question

The chemical reaction between MnO2 and HCl is an example of?
displacement reaction
combination reaction
redox reaction
decomposition reaction​

Answer 1

Explanation:

The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. By means of a stoichiometry, 1 mol of manganese dioxide reacts with 4 mol of HCl (hydrochloric acid) to form 1 mol manganese chloride 1 mol of chloride & 2 mol of water.
