Predict which of the following compounds will be soluble in water. a. agbr b. baso4 c. ca3(po4)2 d. bas

Option (D) is the correct answer.

Explanation:

It is known that silver halides are insoluble in water. Hence, silver bromide which is yellow in color is also insoluble in water.

Solubility of calcium phosphate is which is very low. Hence, calcium phosphate is also insoluble in water.

Similarly, barium sulfate is a white crystalline solid also known as a precipitate and it is insoluble in nature.

When barium sulphide reacts with water then it leads to the formation of barium hydroxide and hydrogen sulphide. Barium sulphide is partially soluble in water.

The reaction equation for this reaction is as follows.

Thus, we can conclude that BaS compound will be soluble in water.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
