Question

write a chemical equation to represent what the model is showing. then, count the numbers of atoms of each element and record in the table

Answer 1

Step-by-step 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:

`\text{ 2H}_(2(g))+O_(2(g))\text{ }\rightarrow2H_2O_((l))`

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
