Use solubility rules to determine if the following will produce a precipitate? (A) 3KBr(aq) + AlPO4(aq) → K3PO4 + AlBr3

(B) ZnCl2(aq) + MgSO4(aq) → ZnSO4 + MgCl2

(C) Na2CO3(aq) + CaCl2(aq) → CaCO3 + 2NaCl

(D) NH4OH(aq) + MgCl2(aq) → Mg(OH)2 + NH4Cl

Which of the above will form a solution NOT a chemical reaction?

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
