Answer:
concave lens
Explanation:
it's concave lens because it diverges the ray/beam of light.
Answer:
2Na=Ca(OH)000.1 AgBr=2KF 2KBr=LiNO
Answer: Option (C) is the correct answer.
Explanation:
Chemical formula of a secondary amide is R'-CONH-R, where R and R' can be same of different alkyl or aryl groups. Here, the hydrogen atom of amide is attached to more electronegative oxygen atom of the C=O group.
Therefore, the hydrogen atom will be more strongly held by the electronegative oxygen atom. As a result, there will be strongly hydrogen bonded in the liquid phase of secondary amide.
Whereas chemical formula of nitriles is RCN, ester is RCOOR' and acid chlorides are RCOCl. As no hydrogen bonding occurs in any of these compounds because hydrogen atom is not being attached to an electronegative atom.
Thus, we can conclude that secondary amides are strongly hydrogen bonded in the liquid phase.

This is what I got, but i'm mot sure if I'm right
first of all there is only two types of selective breeding and they are hybridization and inbreeding.
