Yes, I agree.
Chemistry can be difficult.
Answer:
C
Explanation:
As the temperature increases, the kinetic energy of the molecules increases.
It is referred as a covalent bond
See the image below.
An excited electron is in a <em>high-energy state</em>.
When it drops to the lower-level ground state, it must get rid of this excess energy by <em>emitting it</em> as a quantum of light.
Answer:
Kb = 

Explanation:
For a weak organic base, the formula to find
is given by:

where c is the concentration of base.
Here c= 

Substituting the above values in the formula,we get:

Hence:
Kb =
