Let's break it down:
Al3 = 3 atoms
02 = 2 atoms
Add that up = 5 atoms
Since the coefficient is 2, we multiply that by 2
Hence there are 10 atoms
Most oxygen molecules are composed of two atoms of oxygen, and we frequently refer to oxygen as O2 (or O2) for this reason. Oxygen can also exist as the molecule called ozone, which is O3. Ozone is unstable, and will revert to O2 in a few minutes.
Well, honey, if you're talking about 5.2g of O2, then we need to remember that oxygen comes in pairs in O2 molecules. So, one mole of O2 weighs 32g and contains 6.022 x 10^23 molecules, which means 5.2g of O2 would contain about 1 x 10^23 oxygen atoms. Hope that clears the air for you!
2x(6.02x10^23) -APEX LISTENED TO THAT DUMMY ABOVE ME SMH
1 mole of oxygen contains 6.022 x 1023 atoms. A mole of atoms of any element is 6.022 x 1023 atoms. A mole of anything is 6.022 x 1023 of that thing. For example, a mole of cars is 6.022 x1023 cars.
Nitrogen has 1 atom in a molecule, represented by the chemical symbol N. Oxygen typically exists as O2, with 2 oxygen atoms bonded together.
O2 has 2 atoms of oxygen.
There are 3 atoms in an oxygen molecule (O2).
in the oxygen that we breath there is 2 atoms (O2)
There are a total of 8 atoms in the chemical equation 4Na + O2 → 2Na2O. This can be calculated by adding up the number of atoms on both sides of the equation: 4 sodium atoms from 4Na, 2 oxygen atoms from O2, and 2 oxygen atoms from 2Na2O. Thus, the total number of atoms is 4 + 2 + 2 = 8 atoms.
There are 12 atoms in 6 O2 molecules.
There are two atoms of oxygen on each side.
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
It should be 2Mg+O2 = 2MgO, that is an equation (both sides equal).
Molecules of oxygen exist in two relatively stable allotropes: breathable oxygen with the formula O2, and ozone with the formula O3. The little number indicates that these molecules are composed of (respectively) two or three oxygen atoms.
ONE oxygen molecule (O2) contains two atoms of oxygen (O).
12.54 (g O2) / 2*15.99 (g/mol O2) = 0.3921 mol O2 -->0.3921 (mol O2) * 6.022*1023 (molecules O2)/(molO2) == 2.361*1023 molecules O2= 4.723*1023 atoms O
2 oxygen atoms.
