Deuterium is a relatively uncommon form of hydrogen, but can be created from water.

  • Heavy hydrogen commonly  known as deuterium
  • stable isotopes of hydrogen
  • gets its name from the Greek word deuterons means second.
  • has only one proton and one neutron
  • nucleus of the hydrogen's deuterium atom is known as a deuteron containing one proton and one neutron.
  • Deuterium forms chemical bonds that are stronger than regular hydrogen
  • gas deuterium is colorless
  • Deuterated water is used in Magnetic Resonance Spectroscopy.
  • used in the determination of the isotopologue of various organic compounds.
  • used in Infrared Spectroscopy.

Calculate the entropy change for the reaction: Fe2O3(s) +3C(s) -&gt; 2Fe(s) + 3CO(g)Entropy data:Fe2O3(s): 90 J/K molC(s): 5.7 J
Annette [7]

Explanation:

We are given: entropy of Fe2O3 = 90J/K.mol

: entropy of C = 5.7J/K.mol

: entropy of Fe = 27.2J/K.mol

: entropy of CO = 198J/K.mol

\begin{gathered} \Delta S\text{ = S}_{products}-S_{reactants} \\  \\ \text{       = \lparen3}\times198+2\times27.2)-(3\times5.7+90) \\  \\ \text{       = 541.3J/K.mol} \end{gathered}

Answer:

The correct answer is C.
