Consider the balanced equation below.
8h2 + s8 > 8h2s
based on the mole ratios, what can most likely be predicted?
1 mol of hydrogen will react with 1 mol of sulfur.
8 mol of hydrogen will react with 1 mol of sulfur.
8 mol of hydrogen will react with 8 mol of sulfur.
16 mol of hydrogen will react with 8 mol of sulfur.

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.
