PLEASE HELP PLEASE Octane (C8H18) is a component of gasoline that burns
according to the following equation:
C8H18(l) + 25/2 O2(g) →8 CO2(g) + 9 H2O(g)
ΔΗχη= -5074.1 kJ
What mass of octane (in g) is required to produce 4910kJ of heat?

14 days is the half-life of phosphorus-32

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.
