bekas [8.4K]

Answer:

A solution was NOT formed.

Explanation:

For a solution to be formed, the green powder would need to dissolve in the water to form a homogenous mixture. But since the water was cloudy and had lumps of the green powder, it means that the powder did not dissolve, but instead remained insoluble.

Decide which element probably forms a compound with chlorine that has a chemical formula most and least similar to the chemical
stepladder [879]

The compound formed by chlorine and barium is BaCl_2 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 SrCl_2 in which strontium acts as a cation and chlorine acts as an anion. The formation of the compound is as shown in the image.
