When 84.8 g of iron (III) oxide reacts with an excess of carbon monoxide, iron is produced.
Fe2O3(s) + 3C0 (9) > 2 Fe(s) + 3 CO2 (g)
What is the theoretical yield of iron?

23.5

23.5

47.0

where's the diagram?

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.
