Answer:
The molality of isoborneol in camphor is 0.53 mol/kg.
Explanation:
Melting point of pure camphor= T =179°C
Melting point of sample = = 165°C
Depression in freezing point =
Depression in freezing point is also given by formula:
= The freezing point depression constant
m = molality of the sample
i = van't Hoff factor
We have: = 40°C kg/mol
i = 1 ( organic compounds)
The molality of isoborneol in camphor is 0.53 mol/kg.
Answer: The nuclear equation is .
Explanation:
A nuclear reaction in which a heavy particle splits into another particle along with release of energy is called a nuclear fission reaction.
For example,
Here, energy is radiated in the form of gamma radiation.
Thus, we can conclude that the nuclear equation is .
