Arrange the molecules H2O, NH3, Ar, NaCl in order of expected increasing boiling points. 1. None of these 2. NaCl, H2O, NH3, Ar
Aleks04 [339]

Answer:

Option (4) is correct

Explanation:

  • NaCl is an ionic solid. Na^{+} and Cl^{-} ions are held together by strong coloumbic attractive force. Hence NaCl has highest boiling point'
  • Ar is a monoatomic molecule. Hence only weak london dispersion force exists between Ar atom/molecules. Hence it requires lowest amount of energy to boil and thereby possess lowest boiling point.
  • NH_{3} and H_{2}O are polar protic molecules. Hence they possess london dispersion force, dipole-dipole force and hydrogen bonding as intermolecular forces.
  • Dipole-dipole force is stronger in H_{2}O than NH_{3} due to more polar O-H bond than N-H bond. Also molecular weight of H_{2}O is higher than NH_{3}. So, more energy is required to boil H_{2}O. So, H_{2}O has higher boiling point than NH_{3}

Hence order of boiling point : NaCl>H_{2}O>NH_{3}>Ar

I need help with Hess law
ICE Princess25 [194]

Answer:

alright

Explanation:

Hess law is  the enthalpy change for a reaction that is carried out in a series of steps is equal to the sum of the enthalpy changes for the individual steps. Consistent with the law of conservation of energy. Starting and final conditions must be the same.

What is the difference between chemistry and science
sergeinik [125]

Answer:

hi

Explanation:

chemistry the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

Science the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.

How many nadh molecules are produced on each turn of the citric acid cycle?
Kaylis [27]

Answer:

three NADH molecules

The eight steps of the citric acid cycle are a series of redox, dehydration, hydration, and decarboxylation reactions. Each turn of the cycle forms one GTP or ATP as well as three NADH molecules and one FADH2 molecule, which will be used in further steps of cellular respiration to produce ATP for the cell.
