Reactions & Stoichiometry

Question 1

Johnstone triangle

Answer 1

Molecular level (Electrostatic something map - 3D images and representations)
Symbolic level
Observable level  (Bulk properties)

Question 2

Nitrogen

Answer 2

78% abundant in atmosphere. From a chem’s perspective we draw Nitrogen as a double atom with 3 bonds
N2 is very unreactive due to the triple bond which is non-polar

Question 3

How to make n2 reactive

Answer 3

Use Haber-Bosch process

Question 4

Cans of Balanced equations

Answer 4

Amount of atoms present in a particular ratio within a molecule and across entire equation
Phases of compound

Question 5

Can’t of Balanced equations

Answer 5

The amount of stuff used
Speed of reaction
The mechanism(Reaction steps)
The natural tendency of a reaction
The amount of energy required(thermodynamics)
