1. Hydrogen (H2) and oxygen (O2) combine to make water (H2O) in the following equation.
6H2 + 3O2 → ?H2O
How many water molecules would be produced?
six
2. In photosynthesis, carbon dioxide (CO2) and water (H2O) combine to form the sugar glucose (C6H12O6) in the following reaction:
6CO2 + 6H2O → C6H12O6 + ?
Assuming this equation is balanced, which part is missing from the product side?
12 oxygen atoms
3. Which statement accurately describes what happens in a reaction when reactants become products?
Reactant bonds break and atoms rearrange to form new product combinations.
4. Methane (CH4) and oxygen (O2) combine to make carbon dioxide (CO2) and water (H2O) in the following unbalanced equation.
CH4 + O2 → CO2 + H2O
How many oxygen molecules are necessary in order to complete this reaction?
two
5. Use the equation for the formation of water to answer the question.
2H2 + O2 → 2H2O
Elements such as oxygen and hydrogen naturally exist as diatomic molecules (i.e., in a paired-atom form). Does the equation for the formation of water violate the law of conservation of mass? Why or why not?
No, it does not because the number and mass of atoms are conserved even though the number of molecules is not.
Heyo got a 100% glooks gang
1. The equation as written is not correct. The proper way to write the equation is
2H2 + O2 ==> 2H2O
2. The question you've asked can't be answered BECAUSE you don't say how much hydrogen and how much oxygen are used.
3. However, I think I know what you mean so the balanced equation you have written would be 6H2 + 3O2 ==> 6H2O and I would choose A for the answer.
heyo is 100%
Well, let me check my calculations here. Hmm... It seems like somebody's math is a bit foggy!
The equation clearly states that 6H2 and 3O2 combine to form H2O. So let's think logically for a moment: if we have 6H2 molecules and each H2O molecule needs 2H, then we can divide 6 by 2 to get the number of H2O molecules.
And the answer is... three! So three H2O molecules would be produced in this reaction.
Now, that's not too shabby, is it? Three cheers for water molecules!
To determine the number of water molecules that would be produced, we need to balance the chemical equation. The equation provided is unbalanced, and we need to balance it before we can proceed.
The balanced equation for the reaction of hydrogen and oxygen to form water is:
2H2 + O2 → 2H2O
According to the balanced equation, two molecules of hydrogen react with one molecule of oxygen to produce two molecules of water.
Therefore, the correct answer is six, as six water molecules would be produced when six molecules of hydrogen and three molecules of oxygen react.
