Answer

Explanation:

Step1: Write the balanced chemical equation

$2H_2 + O_2\rightarrow 2H_2O$

Step2: Analyze the molecular - models

In the balanced equation, 2 molecules of hydrogen ($H_2$) react with 1 molecule of oxygen ($O_2$) to form 2 molecules of water ($H_2O$). Each hydrogen molecule has 2 hydrogen atoms bonded together ($H - H$), each oxygen molecule has 2 oxygen atoms bonded together ($O=O$), and each water molecule has 2 hydrogen atoms bonded to 1 oxygen atom ($H - O - H$). The first model shows 2 $H_2$ molecules reacting with 1 $O_2$ molecule to form 2 $H_2O$ molecules, which is consistent with the balanced chemical equation.

Answer:

The first model (the one with two $H_2$ molecules, one $O_2$ molecule, and two $H_2O$ molecules)
