Answer:

D- 31.9988 g/mol

Explanation:

The molar mass of a substance is the mass in grams of one mole of the substance. For a compound, the molar mass is the gram - formula mass or gram - molecular weight. It is determined by the addition of its component atomic masses;

  To find molar mass of O₂;

      Atomic mass of O = 15.9994g/mol

 Molar mass of O₂ = 2(15.9994) = 31.9988g/mol

Rank these systems in order of decreasing entropy. 1 = Greatest entropy and 7 = Least entropy. Group of answer choices 1 mol of
AlladinOne [14]

Answer:

  1. 1 mole of carbon disulfide gas at 273 K and 40 L
  2. 1 mol of chlorine gas at 273 K and 40 L
  3. 1 mol of neon gas at 273 K and 40 L
  4. 1 mol of neon gas at 273 K and 20 L
  5. 1/2 mol of neon gas at 273 K and 20 L
  6. 1/2 mol of neon gas at 100 K and 20 L
  7. 1/2 mol of liquid neon at 100 K

Explanation:

Entropy is the measure of disorder or randomness in a closed system. Its an extensive property of a thermodynamic system

The following points must be considered when ranking the systems according to their entropy:

  1. The entropy of gases are highest than liquids or solid. And entropy of liquid is higher than solid. That is because gas has more microstate thus have the highest entropy.
  2. Entropies of large complicated molecules are greater than those of smaller, simpler molecules. Because larger molecules have more disorder because of the greater number of ways they can be move around in three dimensional space.
  3. highest temperature and highest volume will lead to greatest entropy
  4. 1 mole of any substance will have greater entropy than 1/2 mole of that same substance

14. All the following are necessary parts of a neutralization reaction except A. an indicator. B. a salt. C. water. D. an acid.
ValentinkaMS [17]

The correct answer is <em>B. a Salt </em><em>because The reaction of an acid and a base is called a neutralization reaction because the properties of both the acid and base are diminished or neutralized when they react. A neutralization reaction is a reaction of an acid with a base in aqueous solution to produce water and a salt, as shown by the following equation:</em>

<em>acid + base → salt + water</em>
