Question
Which one is chemical property of matter?
a. Boiling of water
b. Rusting of iron
c. Powdering of chalk
d. Melting of ice
Solution
The chemical property of matter in the options provided is b. Rusting of Iron.
Here's why:
a. Boiling of water - This is a physical change. The water changes from a liquid to a gas, but it's still H2O.
b. Rusting of Iron - This is a chemical change. Rust is iron oxide, a different substance to the iron it came from.
c. Powdering of chalk - This is a physical change. The chalk is still calcium carbonate, just in a different form.
d. Melting of ice - This is a physical change. The ice changes from a solid to a liquid, but it's still H2O.
