b. ethane (C2H6), a nonpolar covalent compound

Explanation:

The substance that would most likely need to cool to the lowest temperature before it condenses is ethane, a non-polar covalent compound.

Ethane in liquid form has very weak attractive forces binding the molecules together.

To form and change state, all the molecules must be brought very close together under very high pressure and low temperature. Else, they will not attract one another.

  • Ionic crystal lattice forces as seen in KBr are strong attractive forces. As a substance such as KBr begins to condense, they begin to attract one another with a very strong force even before they cool to their least temperature.
  • Ammonia has strong intermolecular hydrogen bonds in its structure which binds them together. The attraction is great between the hydrogen of one molecule and the nitrogen of another.
  • In ethane we have a weak attraction.

There are two isotopes of an unknown element, X-19 and X-21. The abundance of X-19 is 14.55%. A weighted average uses the percen
alekssr [168]

Answer:

2.765amu is the contribution of the X-19 isotope to the weighted average

Explanation:

The average molar mass is defined as the sum of the molar mass of each isotope times its abundance. For the unknown element X that has 2 isotopes the weighted average is defined as:

X = Mass X-19 * Abundance X-19 + MassX-21 * Abundance X-21

The contribution of the X-19 isotope is its mass (19.00 amu) times its abundance (14.55% = 0.1455). That is:

19.00amu * 0.1455 =

2.765amu is the contribution of the X-19 isotope to the weighted average
