Question

At one point in the video, someone is balancing a chemical reaction. The person writes a coefficient of 2 in front of Fe2O3 but then writes a 4 for the number of iron (Fe) atoms. Explain this difference.

I really need a answer quick.

Answer 1

answer: the 4 is the product and the other numbers are reactants

Explanation:

i’m pretty sure that’s the answer . i did this last week :)

Answer 2

Four is the product and the other numbers are reactants.

A coefficient is a number that is put in front of a chemical symbol or formula to indicate the number of atoms or molecules of the substances involved in the reaction.

For example:-$4Fe+ 3O_2 \rightarrow2Fe_2O_3$

The number of Fe atoms in the above reaction:- 2 *2 = 4

In the above reaction,  four iron atoms are in the products (two in each of the two iron oxide molecules) and the other numbers are reactants.
