Answer: C-N(Longest) > C=N > CN(C triple bond N, shortest)
Explanation: Bond length is the distance between nuclei of bonded atoms.
Bond energy is the which needs to break the bond.
And bond length is always inversily proportional to bond energy.
Larger the bond energy ,shorter the bond length

Answer:
There are 0.0305 calories in 0.128 joules
Explanation:
Given that,
Heat absorbed, Q = 0.128 J
We need to find the heat energy absorbed in calories.
We know that the relation between joules and calories is as follows :
1 calorie = 4.184 J
1 J = (1/4.184) J
So,

So, there are 0.0305 calories in 0.128 joules
1) D) The amount of space a substance takes up
2) A) The amount of matter in a substance
