Which solution will form a precipitate when mixed with a solution of aqueous na2co3? which solution will form a precipitate when mixed with a solution of aqueous ? nh4cl(aq) k2so4(aq) nabr(aq) cucl2(aq)?

will form a precipitate of insoluble when aqueous is added.

Explanation:

According to solubility rule-

all carbonates are insoluble except group IA compounds and

all salts of sodium are soluble

When is added to given solutions, a double displacement reaction takes place in each solution to form a sodium salt and a carbonate salt.

So, in accordance with solubility rule, addition of into will result precipitation of insoluble

Reaction:

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

lol for the pointsss
