What atoms make up 2O2?
Hydrogen Peroxide Two hydrogen atoms can also bond with two oxygen (O) atoms (peroxide), making the formula H2O2. There is only one more oxygen atom than water (H2O) but it is a totally different compound. You can see that each of the oxygen atoms has eight electrons and the two hydrogens have two electrons each.
How many oxygen atoms are there in 2O2?
four oxygen atoms
There are four oxygen atoms in the formula 2CO2.
How many atoms are in CO2 2H2O?
A coefficient multiplies the number of atoms of each element indicated in a chemical formula. Thus, 2H2O represents four H atoms and two O atoms. Now consider the number of oxygen atoms. There are four oxygen atoms on the right side of the arrow in the partially balanced equation.
How many atoms are in CH4 O2?
Place a coefficient of 2 in front of the O2 . We now have 4 O atoms on both sides. The equation is now balanced. Each side has 1 C atom, 4 H atoms, and 4 O atoms.
How many shells does o have?

| 8 | Oxygen | 2, 6 |
| 9 | Fluorine | 2, 7 |
| 10 | Neon | 2, 8 |
| 11 | Sodium | 2, 8, 1 |
How many atoms are in 2 moles oxygen?
There are 6×6.022×1023 atoms in 2.00⋅mol NO2(g) .
What atoms are in CH4 2O2?
made of the element hydrogen and oxygen. – 2 oxygen atoms.
How many total atoms are in the compound 2h2o?
The chemical formula for water is H2O, which means this molecule has 3 atoms: 2 of hydrogen (H) and 1 oxygen (O) atom.
