Question

the reaction of silver nitrate with zinc would be classified as a
synthesis reaction
double displacement reaction
decomposition reaction
single displacement reaction
consider the following reactants: k3po4 + fe(no3)3 -----> ? + ? the products of the reaction that occurs are:
a) fepo4 + kno3
b) fek3 + no3po4
c) fe3po4 + k3no3
d) k3fe + po4(no3)3
a
b
c
d

Explanation:

1. For the reaction of silver nitrate ($AgNO_3$) with zinc ($Zn$), zinc is more reactive than silver. Zinc will displace silver from silver nitrate. In a single - displacement reaction, one element replaces another element in a compound. The reaction is $Zn + 2AgNO_3=Zn(NO_3)_2 + 2Ag$.
2. For the reaction between $K_3PO_4$ and $Fe(NO_3)_3$, this is a double - displacement reaction. The positive and negative ions of the two reactants exchange partners. The balanced chemical equation is $K_3PO_4+Fe(NO_3)_3 = FePO_4\downarrow+3KNO_3$. The products are iron(III) phosphate ($FePO_4$) and potassium nitrate ($KNO_3$).

Answer:

1. single displacement reaction
2. a) $FePO_4 + KNO_3$
