Ed plans to react 2.1 mols of aluminum with excess water according to the following equation: 2Al + 6H2O = 2Al(OH)3 + 3H2 Ed multiplies 2.1 mols by the ratio 6:2. The product will show him which quantity?
a
The mass of aluminum that enters the reaction
b
The mols of water that react with aluminum
c
The mols of aluminum oxide that the reaction produces
d
The mols of water that remain after the reaction is completed

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.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
