Question

Which of the following is not an example of  a chemical reaction?
  1. Burning of firewood
  2. Rusting of iron rod
  3. Curdling of Milk
  4. Melting of ice


Solution

The correct option is D Melting of ice
The burning of firewood is a chemical reaction where due to fire, wood is changed into ashes.
Rusting of iron is a chemical reaction where iron gets oxidised by the oxygen from air, in the presence of moisture or water. Curdling of milk is a chemical reaction as the chemical form of milk changes by the action of lactobacillus bacteria. Melting of ice is not an example of chemical change as the chemical composition of water remains the same even after melting.
