Astudent is given a 3.147 g mixture of iron fillings, calcium chloride and sand. she separates the mixture and recovers 1.020 g of iron, 1.321 g of sand and 0.753 g of calcium chloride. calculate the percentage of each component she recovered from the original mixture and the percent of material she lost during the separation process. show your steps .

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
