If you have to write the chemical formula of a simple, binary ionic compound given the name of the compound, you follow a set of three steps. Let's go through them using magnesium chloride as an example. Write the symbols for the cation and the anion: Mg and Cl. Determine the charge on the cation and anion.

maxonik [38]

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.

What does the energy hill represent on an energy diagram?
Butoxors [25]

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.
