Answer:
Look on the picture.
Explanation:
He could find only 2 isomers of n-hexane alkenes for this reaction. Other two could be marked from other direction.
Which number represents runoff on the hydrologic cycle diagram?
2 answers:
4
Explanation:
The number 4 in the hydrologic cycle depicts surface runoff.
The hydrologic cycle depicts the cyclic movement of water between different earth components.
It shows water in all its phases.
- From the attached image, runoff is depicted 4.
- Runoff is water that moves on the surface after precipitation.
- Number 1 is evaporation where water changes to vapor.
- Number 2 is condensation where the vapor cools back to liquid.
- Number 3 is precipitation where the liquid water is forced down under gravity.
- On the surface, the water runs as runoff.

Amines are derivatives of Ammonia (NH₃) in which atleast one hydrogen atom is replaced by an alkyl group. Amines are further classifies as;
Primary Amines:
In primary amines the nitrogen atom is attached to two hydrogen atoms and one alkyl group.
Secondary Amines:
In secondary amines the nitrogen atom is attached to two alkyl groups and one hydrogen atom.
Tertiary Amines:
In tertiary amines the nitrogen atom is attached to three alkyl groups, hence it has no hydrogen atom.
Below are three isomers of tertiary amines with molecular formula C₅H₁₃N.
