In its protonated form, bromothymol blue has a molar absorptivity of 13800 m-1•cm-1 at 435 nm. at the same wavelength, the deprotonated form of bromothymol blue has a molar absorptivity of 3410 m-1•cm-1. if a solution contains 2.80 × 10-5 m protonated bromothymol blue and 5.00 × 10-5 m deprotonated bromothymol blue, what is the absorbance of the solution in a 1.00-cm sample cell at 435 nm?

During trial 2, what allowed you to determine that aluminum was the limiting reactant? check all that apply. all of the copper dissolved. all of the aluminum dissolved. the solution turned clear. the number of grams of copper(ii) chloride used in the reaction was greater than the number of grams of aluminum. the molar ratio of copper(ii) chloride to aluminum was greater than 3: 2, the equation’s molar ratio.
