Nitrogen dioxide is NO2 (where the number 2 is a subscript that indicates the number of atoms in one molecule).
Use Avogadro's number: 1 mol of molecules = 6.022 * 10^ 23 molecules.
So, in 5.6 mol of NO2 there are 5,6 mol * 6.022 * 10^23 molecules / mol = 33.72 * 10^23 molecules = 3.372 * 10^24 molecules of NO2.
There are the same number of N atoms (because there is 1 atom of N in 1 molecule) and there are the double of O atoms (becasue there are 2 atoms of O in 1 molecule) => 3.372 * 10 ^24 atomsof N and 6.744 atoms of O.
Answer: 3.372 * 10^24 molecules of NO2, 3.372 * 10^24 atoms of N and 6.744 atoms of O.
Answer:
Four types of molecules important for cell processes:
1. Proteins
2. Carbohydrates
3. Lipids
4. Nucleic Acids
Explanation:
Foremost, Molecules are groups of atoms that bonded and held together by chemical bonds - which form compounds. Cell processes all involve the interaction of molecules and atoms alike. These four groups are absolutely essential for every single organism on Earth. A cell and organism would not be able to live without these vital molecules.

Answer:
5 L.
Explanation:
From the question given above, the following data were obtained:
Initial volume (V1) = 10 L
Initial pressure (P1) = 2.5 atm
Final pressure (P2) = 5 atm
Final volume (V2) =.?
Since the temperature is constant, we shall apply the Boyle's law equation to determine the new volume of the gas. This can be obtained as follow:
P1V1 = P2V2
2.5 × 10 = 5 × V2
25 = 5 × V2
Divide both side by 5
V2 =25/5
V2 = 5 L
Thus, the new volume of the gas is 5 L
