in a chemical equation, which symbol should be used to indicate that a substance is in solution?\n○ (s)\n○ (g)\n○ (l)\n○ (aq)
Answer
Brief Explanations:
To determine the symbol for a substance in solution in a chemical equation, we analyze each option:
- (s) denotes a solid state.
- (g) denotes a gaseous state.
- (l) denotes a liquid (pure liquid, not in solution).
- (aq) stands for "aqueous," which means the substance is dissolved in water (in solution).
So the symbol for a substance in solution is (aq).
Answer:
D. (aq)
