Magnesium bromide is prepared in a laboratory using the reaction below. Typically, the magnesium bromide is recovered as a solid by heating away the remaining water, MgO(s) + 2 HBr(aq) - MgBr2(aq) + H2000
10 940 mole of HBr in solution is added to 16.5 grams of Mgo in a beaker and then is heated until dry, what are the expected contents of the beaker?
0 880 mole of MgBr2(8) and 0.060 mole of Mgo(s)
А
B
0.410 mole of MgBr2(s) and 0.060 mole of MgO(s)
0409 mole of MgBrz(s) and 0.531 mole of HBr(s)
D
0.409 mole of MgBrz(s) and 0.121 mole of HBr(s)

gold is my favorite solid.

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.
