Answer:
To the best of my knowledge, it is because of the amount of gamma rays is given off.
Explanation:
While both are isotopes, Potassium 40 gives off fewer gamma rays compared to Cobalt 60. Potassium 40 isn't really harmful to humans, but Cobalt 60 (I believe) is used in chemotherapy.
Answer:
The correct answer is option D.
Explanation:
When a chemical reaction proceeds the reactants are converted into products. The energy hill represents the potential energy of the reaction.
There are two conditions: If the reaction is endothermic than the energy of the products is greater than the energy of the reactants and ΔH is positive. This energy gain is shown in the form of a peak. In an exothermic reaction, the energy of the products is lower than the reactants and ΔH is negative.
So the suitable option is D which states that the reaction is endothermic and the potential energy gained by the products is higher when a reaction proceeds.
