The molecule contain two atoms: Mg and O.
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
hydrogen oxide is water or H2O and has two hydrogens
Two magnesium atoms would be needed to react with one bromine molecule. Magnesium has a +2 oxidation state, while bromine has a -1 oxidation state. This means that two magnesium atoms are needed to balance the charges when reacting with one bromine molecule.
Magnesium nitrate - Mg(NO3)2 - has 9 atoms in the molecule.
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.
One molecule of oxygen will react with one molecule of hydrogen to produce one molecule of hydrogen peroxide: H2 + O2 --> H2O2 One half molecule of oxygen will react with one molecule of hydrogen to produce one molecule of water: H2 + ½O2 --> H2O ...but nobody would write it like that. It is more correct as follows: 2H2 + O2 --> 2H2O
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
One molecule of iron oxide (Fe2O3) contains two iron atoms per molecule. So, for every molecule of iron oxide, there are two iron atoms, which means one iron oxide molecule contains two iron atoms.
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.
hydrogen oxide is water or H2O and has two hydrogens
Two magnesium atoms would be needed to react with one bromine molecule. Magnesium has a +2 oxidation state, while bromine has a -1 oxidation state. This means that two magnesium atoms are needed to balance the charges when reacting with one bromine molecule.
There are two atoms in the formula unit MgO, or magnesium oxide.

There are 3 atoms in one molecule of MgF2: one magnesium atom and two fluorine atoms.
Aluminum oxide has a chemical formula of Al2O3, which means there are 2 aluminum atoms and 3 oxygen atoms in each molecule of aluminum oxide.
a. 1 iron atom per molecule. in total, two atoms
