Answer:
your answer would be
A.predict the genotypic and phenotypic probabilities of possible offspring
A strong electrolyte like MgCl2 dissociates completely as per the following reaction:
![MgCl_2 ----\ \textgreater \ Mg^{2+} + 2Cl^-](https://tex.z-dn.net/?f=MgCl_2%20----%5C%20%5Ctextgreater%20%5C%20%20%20Mg%5E%7B2%2B%7D%20%2B%202Cl%5E-)
As you can see, from 1 molecule of MgCl2 produces 3 ions on dissociation.
So, 1 mole of MgCl2 produces 3 moles of ions.
Now, Moles of MgCl2 = Volume x Molarity
= 0.04 x 0.345 [Change volume to Litres]
= 0.0138 moles
Now, total moles of ions = 0.0138 x 3 = 0.0414
The cubes have only the same volume, so the answer is c.
Exothermic is when heat escapes an object. So the answer should be the last one.
