Two. The equation means two water molecules, H20. Thus you have 4 hydrogens and 2 oxygens.
3 Hydrogen atoms, 2 Oxygen atoms.
Carbon Dioxide + Water (+ Energy from sunlight) ---> Oxygen + Glucose or 6CO2 + 6H20 (+ Light energy) ---> 6O2 + C6H12O6
One. One hydrogen, one nitrogen, and 3 oxygen (notice the 3 in subscript after the O).
Well, darling, in 3CO2, there are 6 oxygen atoms (3 molecules x 2 oxygen atoms per molecule). In 4H2O, there are 8 oxygen atoms (4 molecules x 2 oxygen atoms per molecule). So, in total, you've got 14 oxygen atoms floating around in that equation. Hope that clears things up for ya!
We know from looking at the molecular formula that one mole of molecules of H2SO4 contains 2 moles of atoms of hydrogen, 1 mole of atoms of sulfur and 4 moles of atoms of oxygen.
There are two atoms of oxygen in an oxygen (O2) molecule.
There are 2 oxygen atoms in 1 molecule of oxygen.
It depends on how many hydrogens are there and how many oxygen atoms there are.
There are four oxygen atoms in one molecule of H3PO4.
There are 2 oxygen atoms in dioxide
There are 3 atoms in an oxygen molecule (O2).
There are 2 atoms and 3 molecules in oxygen.
Heptane has 22 oxygen atoms.
Water + Carbon Dioxide --> Glucose + Oxygen 6H20 + 6CO2 --> C6H12O6 + 6O2 You might be interested to know that aerobic respiration is the opposite : Glucose + Oxygen --> Water + Carbon Dioxide C6H12O6 + 6O2 --> 6H20 + 6CO2
3
glucose and oxygen 6H20 + 6CO2 + energy --> C6H12O6 + 6O2
The oxide Fe2O3 has 3 oxygen atoms in the molecule.
