Answer:
Explanation:
Here, we want to write a chemical reaction
In the first model, we can see that there are 2 molecules of hydrogen gas, reacting with 1 molecule of oxygen to give 2 water molecules
We have the reaction equation as follows:
[tex]\text{ 2H}_{2(g)}+O_{2(g)}\text{ }\rightarrow2H_2O_{(l)}[/tex]
From the reactant side, we can count 4 atoms of hydrogen (a molecule contains 2 atoms, so 2 molecules will contain 4 atoms)
We can also see 2 atoms of oxygen
On the product side, we can see 2 atoms of oxygen and 4 atoms of hydrogen
