Write a molecular equation for the precipitation reaction that occurs. lithium sulfide and strontium iodide. potassium and sodium phosphate.

Answer;

Li2S (aq) + SrI2 (aq) > LiI2 (aq) + SrS (s)

Explanation;

-The precipitate is strontium sulfide. Lithium Iodide will be left in aqueous solution. A precipitation reaction refers to the formation of an insoluble salt (which is the precipitate) when two solutions containing soluble salts are combined.

Second case;

Potassium and sodium phosphate;

No precipitation reaction occurs -because all of the possible products of reaction will remain in aqueous solution.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
