Answer: 21.5kg in grams is 21,500 grams
21.5kg in mg is 215,000,00
Explanation:
<span>While
treating food with gamma rays kills microorganism by damaging their DNA, the energy
of gamma rays rips off electrons from atoms hence ionizing them (causing free radicals).
However, gamma rays do not make the food atoms radioactive. The body has a natural
mechanism of riding the body of free radicals. However, large quantities of radicals in the body can cause
damage.</span>

B hope help you stay happy
Answer:
Explanation:
From the given information:
TO start with the molarity of the solution:

= 0.601 mol/kg
= 0.601 m
At the freezing point, the depression of the solution is 

Using the depression in freezing point, the molar depression constant of the solvent 


The freezing point of the solution 

The molality of the solution is:

Molar depression constant of solvent X, 
Hence, using the elevation in boiling point;
the Vant'Hoff factor 


Answer:
-1160kj/mol
Explanation:
the reaction is exothermic because heat is released to the environment
