These ratios are not identical.
In N2O5 the ratio is 2/5.
In NO2 the ratio is 1/2.
The chemical formula N2O is for the nitrous oxide (nitrogen(I) oxide).
Divide the larger by the smaller mole number. The smaller mole number is assumed to be 1. 0.40/0.20 = 2 As nitrogen is 0.20 moles we have 1 atom of it and 2 atoms of oxygen, so NO2 is the empirical formula (nitrogen dioxide).
9 atoms Here is the formula for ammonium nitrate. NH4NO3 This shows there are two nitrogen atoms, 4 hydrogen, and 3 oxygen. So 1 (nitrogen) + 1(nitrogen) + 4(hydrogen) + 3(oxygen) = 9 atoms
A single nitrogen atom can be chemically reactive while a nitrogen molecule is relatively stable and tends to be faf more inert. A nitrogen molecule also has twice the mass of a nitrogen atom.
nitrogen triiodide
No: The formula NO shows equal numbers of nitrogen and oxygen atoms in the compound, but the formula NO2 shows twice as many oxygen atoms as nitrogen atoms.
Nitrogen dioxide is itself a chemical compound. It consists of 2 atoms of Oxygen and 1 of Nitrogen. Its formula is NO2
This compound is dinitrogen pentoxide.
Nitrogen dioxide, which has the formula NO2.
The chemical formula N2O is for the nitrous oxide (nitrogen(I) oxide).
Hydrogen = H2 Oxygen = O2 Nitrogen = N2
Divide the larger by the smaller mole number. The smaller mole number is assumed to be 1. 0.40/0.20 = 2 As nitrogen is 0.20 moles we have 1 atom of it and 2 atoms of oxygen, so NO2 is the empirical formula (nitrogen dioxide).
There will be three hydrogen atoms per nitrogen atom, forming the compound ammonia with formula NH3.
There are two elements, nitrogen and oxygen. There are seven total atoms, two nitrogen atoms and five oxygen atoms.
Dinitrogen tetroxide has 2 nitrogen atoms and 3 oxygen atoms. Nitrogen has 7 protons and oxygen has 8 protons. So this compound has 38 protons.Oxygen atoms have eight protons each. Nitrogen atoms have seven protons each. So, the given compound has 7x2 + 8x4 = 46 protons.
It should be ONXe but here it is O2N2Xe meaning there are 2 oxygen atoms, 2 nitrogen atoms and 1 Xenon atom. It must be a "special" compound
Nitrogen monoxide has the formula NO, so each molecule of NO contains 1 oxygen atom.
