Balance each chemical equation.
The noble gas argon was discovered by Sir Walter Ramsay and John William Strutt in England in 1895. Through this discovery, they made highly accurate measurements of gas densities. Their experimentally determined densities are:
Oxygen 1.42952 g/L
Nitrogen 1.25718 g/L
Air 1.29327 g/L
1) To determine the density of atmospheric nitrogen, Strutt removed the oxygen, water, carbon dioxide, and argon from air and then filled an evacuated glass tube with the remaining gas. He determined that a mass of 0.20389 g of nitrogen has a density of 1.25718 g/L under standard conditions of temperature and pressure. What is the volume of the glass tube in cm3?
How many grams of water can be cooled from 39 °C to 19 °C by the evaporation of 44 g of water? (The heat of vaporization of
water in this temperature range is 2.4 kJ/g. The specific heat of water is 4.18 J/g.K.)

- In Parts 1 and 2, you noticed some patterns about what kind of substances conduct electricity when dissolved in water, and also how melting points are related. Let's test this pattern by applying it to other substances. Consider the following substances: • Potassium Chloride: KCI • Octadecanol: C18 H380 • Dimethyl Sulfoxide: C2 H6OS • Lithium Bromide: LiBr 1. Based on the patterns you saw in the previous sections, which of those substances do you think will conduct electricity when dissolved in water?
