Answer:
No, two water molecules cannot make 2 O2 and 2 H2 molecules.
Step-by-step explanation:
"materials of two water molecules (H₂O) to make two oxygen molecules (O₂) and two hydrogen molecules (H₂) " can be written as:
2H₂O = 2O2 + 2H2
We need for this to be a balanced equation for it to tell us what will really happen.
Note that there are 4 H and 2 O atoms coming from the reactant (H₂O). On the product side we find 4 O and 4 H atoms. The equation is not balanced. There are more O atoms produced than can be found on the reactant sides.
Let's reduce the number of O2 molecules produced from 2 to 1:
2H₂O = 1O2 + 2H2
Now it is balanced:
Reactants Products
H 4 4
O 2 2
The answer to the question is NO.
The correct statement for producing oxygen and hydrogen from water should be: Two molecules of water can make 1 oxygen (O2) and 1 hydrogen (H2) molecules.
