In Chemistry Please Tell me WHAT is the difference between 2N AND N2?

Question

Chemistry Please Tell me WHAT is the difference between 2N AND N2 (2) IS A Subscript.

Answer 1

2 N means that there are two seperate N atoms, with no bond between them.

N2 means that there are two N atoms bonded together. When atoms are bonded together they are called a molecule. So N2 is a molecule of Nitrogen. 2 N is just two atoms of Nitrogen.

Answer 2

the coefficient 2 tells you the ratio of the number of molecules in a chemical reaction is 2:x (x being the number of molecules of something else)
N2 is the gaseous form of nitrogen, N triple bonded to another N.

Answer 3

2N is normality
A normal is one gram equivalent of a solute per liter of solution. The definition of a gram equivalent varies depending on the type of chemical reaction that is discussed - it can refer to acids, bases, redox species, and ions that will precipitate.

N2 is the gaseous element Nitrogen
Nitrogen is a chemical element which has the symbol N and atomic number 7. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.1% percent of Earth's atmosphere.

Answer 4

2 N means two non bonded Nitrogen atoms

N2 means a nitrogen molecule
