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.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
