(a) predict the products and write the balanced equation including physical states, if no reaction occurs give reasons why (b) classify the type of reaction

Question

16. Chromium metal is added to a solution aluminum sulfate.

17. Solid sodium carbonate is added to sulfuric acid.

18. Aqueous calcium hydroxide is added to perbromic acid.

Answer 1

16). Cr(s) + Al2(SO4)3(aq) ==> No Reaction because Cr is below Al in the activity series and won't replace it

17). Na2CO3(s) + H2SO4(aq) ==> Na2SO4(aq) + CO2 + H2O ... Double replacement

18). Ca(OH)2(aq) + 2HBrO4(aq) ==> Ca(BrO4)2(aq) + 2H2O(l)
