You are given the balanced equation: zn(no3)2 (aq) + na2s (aq) > zns (s) + x what is correct formula for the product represented by x? a. na2(no3)2 (s) b. na2no3 (s) c. nano3 (aq) d. 2 nano3 (aq)

D. 2 NaNO₃

Explanation:

A double displacement reaction is a type of reaction where two reactants exchange ions to form two new compounds. Double displacement reactions typically result in the formation of a product that is a precipitate.

Double displacement reactions take the form:

AB + CD → AD + CB

For the reaction:

Zn(NO₃)₂(aq) + Na₂S(aq) → ZnS(s) + X

If Zn bond with S, NO₃ must be react with Na to produce NaNO₃ that is a soluble salt (Is in aqueous state (aq)). As there are 2 Na and 2 NO₃ the right answer is:

D. 2 NaNO₃
