What is moles of compound?</h3>
Avogadro's number (6.022 x 1023) of molecules (or formula units) make up one mole of a substance (ionic compound). The mass of 1 mole of a chemical is indicated by its molar mass. It provides you with the amount of grams per mole of a substance, to put it another way.
In essence, bond angles indicate that electrons dislike being close to one another. Negative ions are electrons. Negatives don't attract each other. Make a comparison now. A negative person is typically viewed as unpleasant or mean, and you don't want to interact with them.
The configuration or quantity of atoms are not mentioned in an empirical formula. It is typical for many macromolecules, such as silicon dioxide (SiO2), and ionic chemicals, such as calcium chloride (CaCl2).

The balanced equation for formation of NH₃ is as follows;
N₂ + 3H₂ --> 2NH₃
Stoichiometry of N₂ to H₂ is 1:3
when gases react, stoichiometry of reactants applies to volumes as well.
Because 1 mol of any substance occupies 22.4 L at STP.
Therefore stoichiometry of volumes of N₂ to H₂ is 1:3
If N₂ is the limiting reactant,
1 L of N₂ reacts with 3 L of H₂
Therefore 20 L of N₂ should react with - 3/1 x 20 = 60 L
Only 25 L of H₂ is present therefore H₂ is the limiting reactant
ratio of H₂ to NH₃ is 3:2
if 3 L of H₂ forms - 2 L of NH₃
then 25 L of H₂ forms - 2/3 x 25 L = 16.67 L of ammonia
if 22.4 L of NH₃ contains 1 mol of NH₃
then 16.67 L of NH₃ consists of - 1/22.4 x 16.67 =0.74 mol oh NH₃
1 mol of NH₃ is made of 6.022 x 10²³ NH₃ molecules
Therefore 0.74 mol of NH₃ made of 6.022 x 10²³ molecules/mol x 0.74 mol
number of NH₃ molecules formed - 4.45 x 10²³ molecules of NH₃
N₂ is in excess
25 L of H₂ reacts with - 25/3 = 8.33 L
however 20 L present initially
Excess reactant left - 20 - 8.33 = 11.67 L of N₂ remaining
Voltage difference is the push that causes charges to flow from high to low areas.
Ribosomes create RNA, which are used as templates for making proteins
Answer:
Protons are in the middle, electrons are on the loop (outside area) and the neutrons are mixed with the protons.
