13. An indicator that could show a pt change from 4.00 A) bromothymol Mur phenolphthalein + ethyl red orange IV SO + H₂O 14. The heat of combustion of hydrogen sulfide, as shown above, to the nearest hundredth, is x 10² kJ/mol. H₂S+ 15. A few drops of methyl orange are added to a sample of pH 3.8. The colour of the indicator would be A) red + B) yellow orange D) green 16. When a few drops of indicator bromothymol blue are added to a water sample with a pH of 1.44, the colour of the sample is A) blue B) green yellow D) black
