Imagine you need to take a medicine that the doctor has prescribed for you. Explain why scientist who developed that medicine would need to know whether or not the compound in that medicine is polar. How might a polar medicine behave differently within your body than a non-polar medicine word? (Answer in 1 to 2 paragraphs)
According to table 2, which is the strongest bond? Which is the week is fine? Based on what you know about the atomic radii and electronegativity of the elements involved in the bonds, why do you think these to have the most extreme bond-energy values?
How are the bond energies of each bond listed in table two determined?
Why do you think there aren’t bond energy values given in table 2 for N-S and S-I?
Based on tables one and two how would you describe the trend in bond strength of single double and triple bonds?
Based on table 2, how would you describe the trend in strength of bonds formed by the elements carbon nitrogen and oxygen? Would you describe this trend as a periodic trend? Why or why not?

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
