Transcribed Image Text:Background Information: On the Planet ISU, they have different elements, but the atoms bond
based on their valence electrons and electronegativities just as elements do on Earth (e.g. Obeys
the octet rule). The chart below provides the element's symbol, type, number of valence
electrons, and electronegativity.
ve = valence electrons, EN= electronegativity

Transcribed Image Text:3. Explain why a balloon filled with He on a cold winter's day, shrinks when you take it to
your car to take it home from the store. Your explanation should include a description of
the behavior of the gas particles. You may draw pictures to help your explanation if you
want, but it is not required.
4. A balloon filled with helium gas at 20°C occupies 4.91 L at 1.00 atm. The balloon is
immersed in liquid nitrogen at -196°C, while the pressure is raised to 5.20 atm. What is
the volume of the balloon in the liquid nitrogen?
5. Determine the volume, in L, of H,S (at 102°C and 1.20 atm) needed to produce 45.5 g of
S. Assume that there is excess SO, present.
2 H,S(g) + SO,(g) ·
3 S(s) + 2 H,O(g)
6. A basketball is inflated to a pressure of 1.90 atm in a 23.0°C_garage. What is the pressure
of the basketball outside where the temperature is 0.00°C?
