Give scientific reasons
The reaction of zinc powder with dilute hydrochloric acid is much more faster than the reaction of zinc granules with hydrochloric acid when both the reactants are used in same quantity.

Zinc is treated with dilute hydrochloric acid.

Give scientific reasons Aluminium metal reacts much more faster than zinc metal with dilute hydrochloric acid

The reaction of zinc with dilute and concentrated nitric acid, respectively, produce

Give scientific reasons Concentrated hydrochloric acid reacts rapidly with CaCO_3 than dilute hydrochloric acid.

Explain the following reactions with the help of balanced equations: Zinc reacts with dil. hydrochloric acid.

Give Scientific reasons: Conversion of ethanol to ethanoic acid is an oxidation reaction.

Veena observes that during winter setting of milk into curd takes more time while during summer, the same process happens faster. She asks about this difference in time taken to her elder sister. She also asks her sister about why certain reactions occur rapidly while others occur slowly. Her sister explains her about the various factors that affect the rate of chemical reactions. Based on the above scenario, answer the following questions. The reaction of aluminum metal with dilute hydrochloric acid takes place faster as compared to zinc metal. What could be the reason for this difference?

Write chemical equation for the following events: Zinc oxide is dissolved in dilute hydrochloric acid

Explain the following reactions giving their balanced chemical equations: Magnesium is treated with hydrochloric acid.

Give scientific reasons: Zinc powder reacts faster than zinc granules when added to copper sulphate (CuSO_4) solution.
