Chromium reacts with oxygen gas to form chromium(III) oxide. In the balanced chemical equation for this change, what are the lowest, whole number coefficients? Match the number to the species.

=4

=3

=2

Explanation:

We have to start with the formula for each compound, so:

Chromium =

Oxygen gas=

Chromium(III) oxide=

Now we can step up the reaction:

The next step is the balancing process:

We will have a coefficient of "4" for a coefficient of "3" for and a coefficient of "2" for .

its first and third is your answer i did the qustion the fourth isnt right
