Question

select the correct answer.
a substance is followed by the symbol (l) in a chemical equation. what does the symbol represent?
a. the substance has the least molecules in the equation.
b. the substance is in the liquid state.
c. the substance is produced last in the reaction.
d. the substance is dissolved in a liquid solution.
e. the substance is lost at the end of the reaction.

Explanation:

In chemical equations, the symbol (l) is a state symbol. The state symbols are used to indicate the physical state of a substance. (s) is solid, (l) is liquid, (g) is gas, and (aq) is aqueous (dissolved in water). Option A is incorrect as the state symbol has nothing to do with the number of molecules. Option C is wrong because the state symbol doesn't relate to the order of production. Option D is for (aq) (aqueous, dissolved in a liquid solution). Option E is incorrect as the state symbol doesn't imply the substance is lost. So the correct answer is the one related to the liquid state.

Answer:

B. The substance is in the liquid state.
