Textbook Question
Chapter 5, Problem 1SC
Based on the Lewis structures for hydrogen and helium, explain why buoyant balloons are filled with helium instead of hydrogen gas, even though hydrogen gas is cheaper and more buoyant.
a. Helium's duet makes it stable and inert (unreactive).
b. Helium's duet makes it unstable and chemically reactive.
c. Helium has one more electron than hydrogen, which helps add color to the balloon.

Can you show me this problem. Turn them into lewis dot structures for me please and then answer the question because I cant seem to comprehend it/ The diagrams on the picture look too small I guess.
The fire releases 2.80 x 107 Joules of heat energy for each liter of oil burned. The water starts out at 24.5 °C, raising the water's temperature up to 100 °C, and then raises the temperature of the resulting steam up to 325 °C. How many liters of water will be needed to absorb the heat from the fire in this way, for each 1.0 liter of crude oil burned?
4186 J/(kg°C) = heat of water
2020 J/(kg°C) = heat of steam
2,256,000 (i.e. 2.256 x 106) J/kg = latent heat of vaporization for water (at the boiling point of 100 °C).
