On the basis of your understanding of the general solubility guidelines, predict which of the following substances are likely to be soluble in water. a. zinc chloride
b. cobalt(III) sulfide
c. lead(II) nitrate
d. chromium(II) hydroxide
e. lead(II) sulfate
f. magnesium carbonate
g. sodium iodide
h. ammonium carbonate

ZnCl2

sodium iodide

ammonium carbonate

Pb(NO3)2

Explanation:

Substances that dissolve in water can be accurately determined using the solubility rules.

According to the solubility rules, all nitrates are soluble. This implies that lead II nitrate is also soluble in water.

Similarly, all chlorides are soluble in water hence ZnCl2 is soluble in water.

Sulphates are soluble except those of Pb, Ba, Ca and Mg.

Also, NaI is highly soluble in water.

Lastly, all carbonate salts are insoluble except those of sodium, potassium and ammonium. Hence ammonium carbonate is soluble in water.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
