2. 20cm of butane is burned in 150 cm of oxygen. C. Huo(g) + O2(g) → 4CO2(g) + 5H2O(g)
What is the total volume of gas present after complete combustion of the
butane?
A 80cm
B 100cm
C 180cm
D 200cm

answer; i believe that the correct answer is (a) potassium(k)

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.
