L 4.1.4 Quiz: Using the Mole Question 9 of 10
Which of the following best describes an empirical formula?
A. A chemical formula that uses the numbers of atoms of each
element as they actually occur in a molecule
B. A chemical formula that shows the relative number of each type of
atom in a molecule, using the smallest possible ratio
C. A chemical formula that lists the percent composition of each
element
D. A chemical formula that identifies the oxidation state of each
element

B. A chemical formula that shows the relative number of each type of

atom in a molecule, using the smallest possible ratio

Explanation:

The empirical formula of a compound shows the relative number of each type of atom in a molecule and it uses the smallest possible ratio.

it should be all of them because it asks if you included all of those in your answer

explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
