If the tensile strength of the kevlar 49 fibers is 0.550 x 10^6 psi
and that of the epoxy resin is 7 x 10^3 psi,
calculate the strength of a fiber epoxy composite material
that contains 60 percent by volume of kevlar 49 fibers
if the composite is stressed under isostress conditions.

the atomic mass is the bottom number on the element.

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.
