Question

The amount of oxygen in the reactants is 4 atoms. In the products, the oxygen is distributed to water (H2O) and O2 gas. Which coefficients would be placed in front of water and oxygen?

2 in front of water and 2 in front of oxygen
1 in front of water and 2 in front of oxygen
1 in front of water and 1 in front of oxygen
2 in front of water and 1 in front of oxygen

Answer 1

Hey Summer!

Answer 2

So when we're balancing a chemical reaction,

we want to make sure we have the same number of atoms on both sides

so we have something like

4 oxygens + other stuff \(\to\) __H2O + ___ O2

Answer 3

How many oxygens are there in H2O?

and how many oxygens are there in \( \text{O}_2\)
