What information do the coefficients in a balanced chemical equation tell you?
the amount of energy from the products
the ratios of the number of moles of each substance that react and that are produced
the physical states of the compounds reacting
the elements involved in the reaction

The correct answer to your question is the second option

Explanation:

The amount of energy from the products  This option is not correct because in a chemical reaction the energy given off or absorved is written at the end of the reaction, it is not a coefficient.

The ratios of the number of moles of each substance that react and that are produced  This option is correct, coefficients tell the number of moles of each substance in a reaction.

The physical states of the compounds reacting  Physical states are written next to the molecule and using parenthesis.  Incorrect

The elements involved in the reaction Incorrect because elements are written with symbols not with coefficients.

um i think it might be a car?
