Draw the Lewis structure for BCl3. How many single bonds, double bonds, triple bonds, and unshared pairs of electrons are on the
andreev551 [17]

Answer :  The number of single bonds, double bonds, triple bonds, and unshared pairs of electrons on the central atom are, 3, 0, 0 and 0 respectively.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, BCl_3

As we know that boron has '3' valence electrons and chlorine has '7' valence electrons.

Therefore, the total number of valence electrons in BCl_3 = 3 + 3(7) = 24

According to Lewis-dot structure, there are 6 number of bonding electrons and 18 number of non-bonding electrons.

From the Lewis-dot structure we conclude that,

The number of single bonds, double bonds, triple bonds, and unshared pairs of electrons on the central atom are, 3, 0, 0 and 0 respectively.

Show, in a step by step fashion, your calculations to determine the percent
marusya05 [52]

The percent  by volume of a solution : 19.23%

<h3>Further explanation</h3>

Given

50 ml of ethanol

210  ml of water

Required

The percent  by volume of a solution

Solution

Percent Volume (% v/v) : volume (ml) of solute/100 ml of solution ⇒ ratio of the volume of the solute to total volume of the solution

\tt \%solute(v/v)=\dfrac{solute~volume}{solution~volume}\times 100\%

solute= Ethanol

solvent=water

Solution = solute+solvent

Total volume of the solution :

\tt =volume~of~Ethanol+solume~of~water\\\\=50~ml+210~ml\\\\=260~ml

Percent by volume :

\tt \%volume=\dfrac{50}{260}\times 100\%\\\\\%volume=19.23\%
