Concept explainers
(a)
Interpretation:
Whether the property of manganese producing bubbles in acid is a physical or chemical property is to be stated.
Concept introduction:
A physical property of a substance is a characteristic of the substance which does not undergo change with change in composition. A chemical property of a substance defines the reactions of a substance with other substances. A pure substance has a unique set of properties and they remain consistent throughout the sample.
(b)
Interpretation:
Whether the malleability of silver is a physical or chemical property is to be stated.
