Answer:
When you mix silver nitrate and hydrochloric acid it is a chemical
change.
Explanation:
Physical change: You are changing the form of a chemical substance, but not, chemical composition.
- Physical changes are used to separate mixtures into their component compounds, but cannot usually be used to separate compounds into chemical elements or simple compounds.
Chemical Change: Occurs when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
- These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
