K2S(aq) + Co(NO3)2(aq) → CoS (?) + KNO3 (?) a. Write a balanced chemical equation. (1 pt)

b. If a reaction occurs, write the balanced chemical equation with the proper states of matter (i. e. solid, liquid, aqueous) filled in. If no reaction occurs, write “No reaction.” (1 pt)

c. If a reaction occurs, write the net ionic equation for the reaction. If no reaction occurs, write “no reaction.” (1pt)

5. You have an aqueous solution of lithium sulfate (Li2SO4). Using ONLY the list of ions in Figure 1 and the list of solubility rules in Figure 2, complete the following steps. Remember to follow lower numbered rules first.

a. Name an ionic compound (cations and anions combined) that 1) is soluble in water on its own and 2) when mixed with an aqueous solution of Li2SO4, forms a solid precipitate (1 pt)

b. Write the net ionic equation for the reaction between Li2SO4 and the compound you chose. (2 pts)
