The chemical reaction is:
N2 + 3 H2 = 2 NH3
For six molecules of nitrogen N2 18 molecules of hydrogen H2 are needed.
Two atoms of sodium are required to react with one molecule of Br2 to form sodium bromide. Therefore, to completely react with 5 molecules of Br2, you would need 10 atoms of sodium.
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.
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.
To determine the number of moles of beryllium chloride required to react with 15 g of silver nitrate, you first need to write the balanced chemical equation for the reaction between beryllium chloride (BeCl2) and silver nitrate (AgNO3). Then, use the molar ratio between the two reactants to calculate the moles of BeCl2 required to react completely with the given amount of AgNO3.
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.
Two atoms of sodium are required to react with one molecule of Br2 to form sodium bromide. Therefore, to completely react with 5 molecules of Br2, you would need 10 atoms of sodium.
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.
160...cant quite grasp HOW though
In the process of photosynthesis, 6 molecules of carbon dioxide react with 6 molecules of water to form one molecule of glucose and 6 molecules of oxygen. Thus, 12 molecules of hydrogen are required to form one molecule of glucose (from the 6 molecules of water).
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.

2.
the molecules in the reaction react in ratios. for eg in water it is Hyogen and water in the ration 1:2. these ratios tell you how many of the atoms are required for the reaction.
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 8 atoms of iron react with 6 molecules of oxygen, they will form 4 units of iron oxide (Fe2O3) because each molecule of iron oxide contains 2 atoms of iron and 3 atoms of oxygen.
The number of water molecules obtained is 120,44281714.10e23.
