which feature of a chemical equation represents the law of conservation of matter?

chemical formulas

coefficients

balanced equation

subscripts

The answer to your question is a balanced equation

Explanation:

Chemical formulas  are extremely useful in chemistry and these formulas follow the law of proportions but not the law of conservation of matter.

Coefficients  indicate that an equation is balanced if these numbers are in proportion but it is not the answer.

Balanced equation  is a feature of the law of conservation of matter.

Subscripts are necessary for chemical reactions but they are not a feature of the law of conservation of matter.
