The molecule CCI4 contains one double bond and three single bonds. True or False
kifflom [539]

False

Explanation: Carbon is the central atom which has valency of 4 and can form 4 bonds to complete its octet. Each chlorine has valency of 1 and can form only one bond to complete its octet. Thus carbon can bond with four chlorine atoms through sharing of electrons to form four single bonds. Thus it cannot contain a double bond.

The lattice energy of a salt is related to the energy required to separate the ions. For which of the following pairs of ions is
Kay [80]

Answer: The Lattice energy is the energy required to separate an ionic solid into its component gaseous ions <em>or</em>

It is the energy released when gaseous ions combine to form an ionic solid.

Explanation:

The lattice energy depends on the ionization energies and electron affinities of atoms involved in the formation of the compound. The ionization energies and electron affinities also depends on the ionic radius and charges of the ions involved. As the ionic radius for cations <em>increases</em> down the groups, ionization energy <em>decreases</em>, whereas, as ionic radii <em>decreases</em> across the periods , ionization energy <em>increases</em>. The trend observed for anions is that as ionic radii <em>increase </em>down the groups, electron affinity <em>decreases. </em>Across the period, as ionic radii <em>increases</em> electron affinity <em>increases</em>. Also, as the charge on the ion <em>increases,</em> it leads to an <em>increase</em> in energy requirement/content.

Therefore, for compounds formed from cations  and anions in the same period, the highest charged cation and anion will have the highest lattice energy. For example, among the following compounds: Al2O3 (aluminium oxide), AlCl3 (aluminium chloride), MgO, MgCl2 (magnesium chloride), NaCl, Na2O (sodium oxide); Al2O3(aluminium oxide) will have the highest lattice energy, thus will be hardest to break apart because its ions have the highest charge.

7. Compare and contrast a dilute solution of a strong acid
Cloud [144]

Explanation:

An acid is a substance that ionizes to produce excess hydrogen ion in solutions.

  • A concentrated acid contains a high amount of hydrogen ions in solution compared to other ions.
  • Such solutions usually ionizes completely.
  • A dilute solution contains a high proportion of water and with low amount of hydrogen ions.
  • They do not ionize easily and as fast as strong acids.
