CHEM 219 EXAM 1 QUESTIONS WITH ALL CORRECT ANSWERS Describe how individual resonance structures impact the true structure of a molecule or polyatomic ion. - Answer Each contributing individual resonance structure contributes characteristics to the overall hybrid structure of the compound. The hybrid "averages" bond lengths and formal charges by delocalizing them among atoms that share them in each contributing individual resonance structure. On a piece of scrap paper, draw the resonance s...

1. Which of these properties is/are characteristics(s) of gases? 2. If the amount of a gas is tripled and the volume of the container is also tripled the new pressure of the gas will: 3. You’re at the zoo and have a big red 3.200 L helium balloon. The barometric pressure is 790.0 mm Hg. Then you hear the roar of a lion. Startled, you accidently release the balloon. It flies away. By the time it reaches the clouds the atmospheric pressure is only 0.3000 atm. What is the new volume of the balloo...
