Question

Single-replacement and double-displacement reactions are given below. Use the activity series to find out whether a reaction would occur and identify the products of such reactions.

3Pb(s) + 2H3PO4(l) →
CaSO4(s) + Mg(OH)2(aq) →
2Al(s) + 3CuCl2(aq) →
2Ag(NO3)2(aq) + CuSO4(aq) →
2HgO(s) heat→
2Al(s) + 3Br2(g) →

Answer 1

Single-replacement reactions involve the replacement of one element in a compound with another element. The activity series can be used to predict whether a reaction will occur based on the reactivity of the elements involved. The balanced chemical equation for F2 + FeI3 is F2 + 2FeI3 → 2FeF3 + 3Cl2.

Step-by-step explanation:

Single-replacement reactions involve the replacement of one element in a compound with another element. To determine whether a reaction will occur, you can consult the activity series. If the element attempting to replace another element is more reactive, the reaction will occur. For example, in the reaction F2 + FeI3, fluorine (F2) is more reactive than iron (Fe) and therefore the reaction will occur. The products of the reaction will be FeF3 and Cl2. The balanced chemical equation is: F2 + 2FeI3 → 2FeF3 + 3Cl2.
