Classify the following as physical or chemical properties
(a) The composition of a sample of steel is 98% iron, 1.5% carbon and 0.5% other elements.
(b) Zinc dissolves in hydrochloric acid with the evolution of hydrogen gas.
(c) Metallic sodium is soft enough to be cut with a knife.
(d) Most metal oxides form alkalis on interacting with water.
Physical property:
(a) Composition of a sample of steel is 98% iron, 1.5% carbon and 0.5% other elements. It is physical property because no new compound is formed as the steel is an alloy and alloy and is a homogeneous mixture of two or more metals or of metallic elements with non-metallic elements.
(c) The cutting of sodium metal does not involve any chemical reaction, hence, it is a physical property.
Chemical property:
(b) It is a chemical property because zinc reacts with HCL to form zinc chloride and hydrogen gas.
(d) It is chemical property as a new compound is formed by the interaction of metal oxides with alkalis.
