Which of the following statements best explains the decreased acidic nature of carbonic acid compared to other carboxylic acids? OH carboxylic acid HO OH carbonic acid A. The extra hydroxyl group on the carbonic acid is an electron donating group, dampening the acidity of the molecule. B. The carbonyl group is an electron withdrawing group, increasing acidity of the OH through resonance. C. The carboxylate anion is stabilized by hyperconjugation and is a weak base, so the conjugate acid is...

Question 10 4 pts Which of the following explanations best explains, from first principles, the fact that boron has a lower first ionization energy than beryllium? 0 Beryllium has more core electrons than boron. 0 Boron is more boring and hence it will be easier to remove the bored electrons from the shell. Electrons are more closely bound in beryllium because God invented the Octet Rule, such that beryllium is closer to an octet than boron. 0 In beryllium, an...

3. Which of the following statements best explains why nitrogen gas at STP is less dense than Xe Has at STP? a) Because Xe is a noble gas, there is less tendency for the Xe atoms to repel one another, so they pack more densely in the gas state. b) Xe atoms have a higher mass than N2 molecules, Because both gases at STP have the same number of molecules per unit volume, the Xe gas must be denser, c)...
