Question:

Complete and balance each other following formula units or net ionic equation write Nr if no reaction occurs include the state (s,l,g, or aq) of all products.

{eq}a.\ Ni(s)\ +\ 2Na^{+}\ (aq)\rightarrow \\ b.\ Ba\left ( OH \right )_{2}(aq)\ +\ H_{2}SO_{4}(aq)\rightarrow \\ c.\ NH_{3}(aq)\ +\ HClO_{4}(aq)\rightarrow \\ d.\ HCO_{3}^{-}\ (aq)\ +\ OH^{-}\ (aq)\rightarrow \\ e.\ NH_{4}Cl(aq)\ +\ Li_{3}PO_{4}(aq)\rightarrow \\ f.\ Pb\left ( NO_{3} \right )_{2}(aq)\ +\ MgSO_{4}(aq)\rightarrow {/eq}

Single and Double Displacement Reactions:

A single displacement occurs when a more reactive metal reacts with a salt of a less reactive metal to produce the less reactive metal and the salt of the more reactive metal. A double displacement reaction is when two ionic compounds react and interchange their cations and anions to form two new compounds. A double displacement reaction only proceeds when at least one of the products is a weak electrolyte, an insoluble precipitate or a gas.

Answer and Explanation: 1


a. {eq}Ni(s)\ +\ 2Na^{+}\ (aq)\rightarrow NR {/eq}

b. {eq}2 Ba\left ( OH \right )_{2}(aq)\ +\ H_{2}SO_{4}(aq)\rightarrow 2BaSO_4(s)+2H_2O(l) {/eq}

c. {eq}NH_{3}(aq)\ +\ HClO_{4}(aq)\rightarrow NH_4ClO_4(aq) {/eq}

d. {eq}HCO_{3}^{-}\ (aq)\ +\ OH^{-}\ (aq)\rightarrow CO_{3}^{2-}(aq)+H_2O(l) {/eq}

e. {eq}NH_{4}Cl(aq)\ +\ Li_{3}PO_{4}(aq)\rightarrow NR {/eq}

f. {eq}Pb\left ( NO_{3} \right )_{2}(aq)\ +\ MgSO_{4}(aq)\rightarrow PbSO_4(s)+Mg(NO_3)_2(aq) {/eq}
