How many hydrogen atoms are in the compound represented by the following bond-line drawing?
ОН

Answers

Answer:

Theres no drawing

Explanation:

Show drawing

Skeletal structural diagram and bond-line drawing are similar;

Parts of the question appear missing: The number of hydrogen atoms in the attached example bond-line drawing is 6 hydrogen atoms

The reason the above value is arrived at for the attached example bond-line diagram is as follows;

A bond-line drawing is the diagram showing the molecular structure of a compound, such that covalent bonds within the molecule are represented by lines with the number of lines indicating the number of covalent bonds.

A single covalent bond is represented by one line, double bonds by two lines while three parallel lines represents a triple bond.

In bond-line drawing, the lines symbolically infer the carbon to carbon bonds while the bonds to the hydrogen atoms are implied noting that each carbon has four covalent bonds. Hydrogen atoms attached to other heteroatoms are indicated with an H.

The number of hydrogen shown in the example diagram can be found by noting that the number of covalent bonds between the carbon atoms are three, therefore, the atom of the fourth bond not shown with a line is to a hydrogen atom

There are six such carbon atoms, one of which is attached to an oxygen atom, which gives five hydrogen atoms located on the ring

There is one more hydrogen atom attached to the oxygen in the hydroxyl group, the total number of hydrogen is therefore;

5 hydrogen on ring + One hydrogen in the hydroxyl group = 6 hydrogen atoms

A solution is prepared by dissolving 10.6 g sodium carbonate in enough water to produce
500.0 mL solution. What is the molarity of sodium carbonate in the solution?

Answers

Answer:

0.2mol/dm³

Explanation:

Given parameters:

Mass of Na₂CO₃   = 10.6g

Volume of solution  = 500mL

Unknown:

Molarity of solution  = ?

Solution:

The molarity of a solution can be determined using the expression below:

 Molarity = [tex]\frac{number of moles }{volume}[/tex]  

     Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

Molar mass of Na₂CO₃ = 2(23) + 12 + 3(16)  = 106g/mol

   Number of moles  = [tex]\frac{10.6}{106}[/tex]   = 0.1mol

   Convert mL to dm³;

        500mL will give 500 x 10⁻³dm³or 0.5dm³  

So;

Molarity  = [tex]\frac{0.1}{0.5}[/tex]    = 0.2mol/dm³
