Suppose you start with 1.000 g of an unknown copper compound and isolate 0.9794 g of metallic copper. What is be the formula weight of the compound if there is only one copper atom per unit formula

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 awnser is group 12

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
