Well, 1 molecule of water is made up of 2 hydrogens and 1 oxygen. And it is not possible to have 1/2 a molecule of water, therefore, you have to have at least 1 complete oxygen in there, not 1/2.
None. A water molecules contains one oxygen atom and two hydrogen atoms. Oxygen only contains oxygen.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.

No, the chemical formula for water is H2O. This means that for every oxygen atom in the compound, there are two hydrogen atoms. Thus, the number of hydrogen atoms in water is double the number of oxygen atoms.
A half mole of oxygen contains approximately 3.01 x 10^23 oxygen atoms. This is because one mole of any substance contains Avogadro's number of atoms or molecules, which is 6.022 x 10^23. So, half a mole would contain half of that amount.
H2O and OH- are added to balance the oxygen atoms.
In half a gram of ice, there are approximately 1.25 x 10^22 molecules of water (H2O). Each water molecule consists of 3 atoms (2 hydrogen, 1 oxygen). Therefore, in half a gram of ice, there are approximately 3.75 x 10^22 atoms.
The correct answer is A. There are 2 hydrogen atoms. The equation "H2O" indicates that each water molecule consists of two hydrogen atoms and one oxygen atom. Therefore, the statement regarding hydrogen atoms is accurate, while the other options are incorrect.
H2O and OH- are added to balance the oxygen atoms.
3 oxygen atoms, so one and a half oxygen molecules. 3 Oxygen atoms joined by a single and a double bond in a bent shape, it is one molecule. A normal molecule of Oxygen has two atoms joined by a double bond.
After one half-life, half of the original radioactive atoms will decay, leaving 600 atoms. After a second half-life, another half of the remaining atoms will decay, leaving 300 atoms that have disintegrated out of the original 1200 atoms.
Yes. You would eventually get to a point where you would have only 1 molecule remaining. A molecule of water for instance has 2 hydrogen atoms and 1 oxygen atoms. If you tried to divide that in half it would destroy it and it would no longer be water.
