Answer:
Explanation:
The formula for the amount of heat absorbed by a substance is
q = mCΔT
Thus, the three factors are the
The only factor that is on your list is
The shape of the substance has no effect, nor do its melting and boiling points.
The compound formed by chlorine and barium is as the number of valence electrons in barium is 2 and in chlorine is 1. In this compound, barium acts as a cation and chlorine acts as an anion. The formation of the compound is as shown in the image.
Since, barium is an element of Group-2 (alkaline earth metal) so the other element that has a chemical formula most and least similar to the chemical formula of the compound formed by chlorine and barium should be from Group-2 (alkaline earth metal) only which has properties somewhat like barium. So, the element is strontium.
Strontium forms a compound with formula in which strontium acts as a cation and chlorine acts as an anion. The formation of the compound is as shown in the image.
