Amixture of aluminum and iron weighing 9.62 g reacts with hydrogen chloride in aqueous solution according to the parallel reactions 2 al + 6 hcl -> 2 alcl3 + 3 h2 fe + 2 hcl -> fecl2 + h2 a 0.738 g quantity of hydrogen is evolved when the metals react completely. calculate the mass of iron in the original mixture. suppose that in the previous reaction i also get 15.95 g alcl3. what is the percent yield of alcl3?
