identify whether each of the following is a chemical reaction: a. melting ice b. burning a candle c. rusting…

Explanation:

Step1: Define chemical reaction

A chemical reaction results in a new - substance formation with different chemical properties.

Step2: Analyze melting ice

Melting ice is a physical change. Ice (solid water) changes to liquid water. The chemical composition ($H_2O$) remains the same. So, it is not a chemical reaction.

Step3: Analyze burning a candle

Burning a candle involves the reaction of wax (hydrocarbons) with oxygen. New substances like carbon - dioxide and water vapor are formed. So, it is a chemical reaction.

Step4: Analyze rusting iron

Rusting iron is the reaction of iron with oxygen and water in the air to form iron oxide (rust). New chemical substances are formed. So, it is a chemical reaction.

Answer:

a. Not a chemical reaction b. Chemical reaction c. Chemical reaction
