The chemical reaction is:N2 + 3 H2 = 2 NH3For six molecules of nitrogen N2 18 molecules of hydrogen H2 are needed.
Two atoms of iron are needed to completely react with three molecules of oxygen to form two molecules of iron(III) oxide (Fe2O3). Each iron atom will lose three electrons to form Fe3+ ions, while each oxygen molecule will gain two electrons to form O2- ions.
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
If we have 150 nitrogen molecules, we would need an equal number of hydrogen molecules to react with them according to the balanced reaction equation for the formation of ammonia: N2 + 3H2 → 2NH3 Therefore, we would need 150 hydrogen molecules to react with 150 nitrogen molecules.
If all the magnesium atoms are going to react, they will each need to combine with two oxygen atoms to form magnesium oxide. Therefore, for 100 magnesium atoms, you would need 200 oxygen atoms, which is equivalent to 100 oxygen molecules.

To react completely with one molecule of methane (CH4), two molecules of oxygen (O2) are needed. This is because the balanced chemical equation for the combustion of methane is CH4 + 2O2 → CO2 + 2H2O. Each molecule of methane requires two molecules of oxygen to form carbon dioxide and water.
