For each of the following pairs of substances, determine which has the larger molar entropy at 298 K: (A) Br₂(l) or (B) Cl₂(g) (
irakobra [83]

Explanation:

Entropy is defined as the degree of randomness present in a substance. Therefore, more is the irregularity present in a compound more will be its molar entropy.

Hence, decreasing order to molar entropy in state of matter is as follows.

                     Gases > Liquids > Solids

  • In the first pair, we are given Br_{2}(l) or Cl_{2}(g). Since, molar entropy of liquids is less than the molar entropy of gases.

Hence, Cl_{2}(g) will have larger molar entropy as compared to Br_{2}(l).

  • In the second pair, we are given Fe(s) or Ni(s). More is the molar mass of a compound more will its molar entropy. Molar mass of Fe is 55.84 g/mol and molar mass of Ni is 58.69 g/mol.

Hence, molar entropy of Ni(s) is more than the molar entropy of Fe(s).

  • In the third pair, we are given C_{2}H_{6}(g) or C_{2}H_{4}(g). As both the given species are gaseous in nature. So, more is the molar mass of specie more will be its molar entropy.

Molar mass of C_{2}H_{6}(g) is 30.07 g/mol and molar mass of C_{2}H_{4}(g) is 28.05 g/mol. Therefore, molar entropy of C_{2}H_{6}(g) is more than the molar entropy of C_{2}H_{4}(g).

  • In the fourth pair, we are given CCl_{4}(g) or CH_{4}(g). Molar mass of CCl_{4}(g) is 153.82 g/mol and molar mass of CH_{4}(g) is 16.04 g/mol.

Therefore, molar entropy of CCl_{4}(g) is more than the molar entropy of CH_{4}(g).

  • In the fifth pair, we are given HgO(s) or MgO(s). Molar mass of HgO is 216.59 g/mol and molar mass of MgO is 40.30 g/mol.

Hence, molar entropy of HgO(s) is more than the molar entropy of MgO.

  • In the fifth pair, we are given NaCl(aq) or MgCl_{2}(aq). Molar mass of NaCl 58.44 g/mol and molar mass of MgCl_{2}(aq) is 95.21 g/mol.

Hence, the molar entropy of MgCl_{2}(aq) is more than the molar entropy of NaCl(aq).

214 Po goes under alpha decay what is the equation?
Katyanochek1 [597]
Alpha decay represents the forceful ejection of two protons and two neutrons from the nucleus of the parent atom. If 214 Po undergoes alpha decay, the equation would be:

214 Po ➡️ 210 Pb + 4 He + energy

Alpha decay is in the form of a helium nucleus, two protons and two neutrons.
