8.
Hydrogen sulfide = H2S
Iron(III)hydroxide = Fe(OH)3
Iron(III)sulfide= Fe2S3
Water= H2O
H2S(g) + Fe(OH)3(s) -------------- Fe2S3(s) + H2O(g)
3 H2S(g) + 2 Fe(OH)3(s) -------------- Fe2S3(s) + 6 H2O(g)
9)
a) UO2(s) + HF(l) ----------- UF4(s) + H2O(l)
UO2(s) + 4 HF(l) ------------- UF4(s) + 2 H2O(l)
b) Na2O2(s) + H2O(l) ------------ NaOH(aq) + O2(g)
2 Na2O2(s) +2 H2O(l) ------------ 4 NaOH(aq) + O2(g)
c) B2O3(s) + NaOH(aq) ----------- Na3BO3(aq) + H2O(l)
B2O3(s) + 6 NaOH(aq) ----------- 2 Na3BO3(aq) +3 H2O(l)

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
