Answer:

     (a) Constitutional Isomers

     (b) Constitutional Isomers

Explanation:

Constitutional isomers are also known with the name Structural Isomers. These are the compounds which have same chemical formula but differ in arrangement of atoms i.e. structure.

Both the compounds <em>cis-1,3-dibromocyclohexane</em> and <em>trans-1,4-dibromocyclohexane</em> have the same chemical formula C_{6} H_{10} Br_{2} but have different structure as shown in the image below.

In the second case the compounds <em>2,3-dimethylhexane</em> and <em>2,3,3-trimethylpentane</em>, both have same chemical formula C_{8} H_{18} but have different structures which is shown in the image below.

Thus it is clear that in both the groups (a) and (b) the given compounds are Constitutional Isomers.

QveST [7]

Answer:

: The conductivity of electrolyte solutions: (a) 0.1 M NaCl (b) 0.05 M NaCl (c) 0.1 M HgCl2. An electrolyte solution conducts electricity because of the movement of ions in the solution (see above). The larger the concentration of ions, the better the solutions conducts. Weak electrolytes, such as HgCl2, conduct badly because they produce few ions when dissolved (low concentration of ions) and exist mainly in the form of molecules.

How many grams of iron(III) oxide (Fe(OH)3) may theoretically be produced from 85.0 g FeCl3?
Crank

Answer:

56.0 g

Explanation:

Calculation of the moles of FeCl_3 as:-

Mass = 85.0 g

Molar mass of FeCl_3 = 162.2 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{85.0\ g}{162.2\ g/mol}

Moles= 0.52404\ mol

According to the reaction:-

FeCl_3+3 NaOH\rightarrow Fe(OH)_3+3 NaCl

1 mole of FeCl_3 on reaction forms 1 mole of Fe(OH)_3

Also,

0.52404 mole of FeCl_3 on reaction forms 0.52404 mole of Fe(OH)_3

Moles of Fe(OH)_3  = 0.52404 moles

Molar mass of Fe(OH)_3  = 106.867 g/mol

Mass = Moles*Molar mass = 0.52404\times 106.867\ g = 56.0 g
