There are 2 Oxygen atoms in CaCO2
There are 2 oxygen atoms in dioxide
It depends on how many hydrogens are there and how many oxygen atoms there are.
There are 2 atoms and 3 molecules in oxygen.
One! You may mean to ask how many atoms there are in one molecule of oxygen, in which case the answer is two.
Two oxygen atoms.
There are 2 Oxygen atoms in CaCO2
Four oxygen atoms.
There are 2 oxygen atoms in dioxide
It depends on how many hydrogens are there and how many oxygen atoms there are.
2NO + O2 --> NO2 is not balanced. There are two nitrogen atoms on the left and only one on the right. There are four oxygen atoms on the left and only one on the right. The correct balanced equation is 2NO + O2 --> 2NO2.
There are 2 atoms and 3 molecules in oxygen.
It has 4 oxygen atoms.
A Molecule of Oxygen contains two atoms
3
There are 2 oxygen atoms in 1 molecule of oxygen.
in the oxygen that we breath there is 2 atoms (O2)
