Question
Chapter 2, Problem 14A
Interpretation Introduction
Interpretation:
The conditions of chemical changehave to be stated.
Concept Introduction:
Matter has both physical and chemical properties.
Chemical properties are defined as the ability of a substance to transform into another different substance.
A chemical change involves the change of a substance into other new substances.
Expert Solution & Answer
Answer to Problem 14A
The five conditions of chemical change:
- change in color
- formation of a precipitate
- formation of a gas
- change in smell
- temperature change
Explanation of Solution
- Change in color: A change in color is an indicationof a chemical change.
- Formation of a precipitate: Sometimes a precipitate can be formedby mixing two liquids which is an indication of a chemical change.
- Formation of a gas: The formation of gas bubbles during a chemical change is an indication.
- Change in smell: Change in smell is an indication of chemical change. An odorless substance can change into another substance with bad smell.
- Temperature change: Most of the chemical changes are associated with gain or release of temperature.
