An aqueous solution contains the following ions: Cl−, F−, HCO−3, Mg2+, and NH+4. Is a precipitate likely to form? If so, give the formula of the precipitate. A )Mg(HCO3)2
B) MgF2
C) NH4F
D) No precipitate will form

B) MgF2

MgF2

Explanation:

Since the solution is an aqueous solution, then we must recall that only species that are soluble in water will dissolve in it. Chemical substances that are not soluble in water will separate out of the aqueous solution as a precipitate.

Magnesium fluoride is insoluble in water, the fluorides of other group two elements are also markedly less soluble than their corresponding chlorides, bromides and iodides. This lower solubility of alkaline metal fluorides has been related to the extremely high lattice energy of the alkaline metal fluorides. Recall that ionic substances with extremely high lattice energies are often insoluble in water. Hence the answer written above.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
