Molecular compound consists of molecules whose formula represents the actual number of atoms bonded together in the molecule. While ionic compound are ions that gain or lose electrons resulting in a positive or negative charge.
This means that there are 7 protons in the nucleus of a nitrogen atom.
In chemistry:
When something is oxidized, it loses electrons.
When something is reduced, it gains electrons.
So the correct statements would be the second to last and third to last statements
Answer:
0.08 moles
Explanation:
Relative atomic mass of KMnO4 = K + Mn + O4 = 39 + 55 + 16 x 4 = 158
=> Moles in 13g of KMnO4 =
=
= 0.082278.. = 0.08 moles
