The answer is “the sustainability of the ecosystem” because if the ecosystem isn’t sustainable enough for many different organisms to live in it then the biological diversity of the ecosystem will decrease.
Answer:
atom is the smallest unit of matter that has the characteristic properties of a chemical element.
A control group is the group in an experiment that does not receive any sort of change, to then be compared to the other treated objects at the end of the study.
Mass:20g
Mole=20/[2(23)+16]
=0.32 mil

Explanation:
Alkynes are hydrocarbons and they are very acidic because of hybridization effect(the more acidic the s-character is, the more acidic it is going to be).
The reaction of 1-hexyne with sodium amide in liquid ammonia is a form of deprotonation 'reaction' to form acetylide. Due to the acidic nature of the terminal hydrogen atom, terminal alkynes do form metallic derivatives by the replacement of the terminal hydrogens. The equation of Reaction is given below.
C6H10 + NaNH2( in liquidNH3) ------------> C6H9Na + H-NH2.
The acetylide is a bae and a very good nucleophile.
The reaction is then followed by the addition of 1-bromobutane. This reaction is used for the production of longer chain alkynes. The equation of Reaction is attached in the picture.
