Question 3 multiple choice worth 5 points)
(02.06 lc)
three sections of the periodic table are labeled a, b, and c in the image below.
which of the following statements is most likely true for an element present in section c?
it is dull and brittle as a solid.
it has a high density.
it is malleable and ductile.
it is a good conductor of electricity.
tan
t
o

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.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
