Which information does the chemical formula co2 not give you? A. number of valence electrons in each atom
B. ratio of atoms in the compound
C. total number of atoms in one molecule of the compound
D. type of elements in the compound

Considering the definition of chemical formula, the correct answer is option A): number of valence electrons in each atom.

A chemical formula is the representation of the elements that make up a compound and the proportion in which they are found, or the number of atoms that make up a molecule.

In other words, a chemical formula is an alphanumeric expression that is used to indicate the composition of a chemical substance and that is constructed from the symbols of its constituent elements, affected by numerical subscripts that report the number of atoms of each element that it is part of the substance.

In summary, the correct answer is option A): number of valence electrons in each atom.

A

Explanation:

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
