In order to separate the components of a binary mixture, the relative volatility should be a) less than unity b) equal to unity
Tresset [83]

Answer: Option (c) is the correct answer.

Explanation:

A binary mixture is defined as the mixture which contains two components in the aqueous medium. The two components are solute and solvent.

And, volatility is defined as the ability of a liquid solution or substance to readily change into vapors.

For a binary solution the expression for relative volatility is as follows.

              \alpha = \frac{\frac{y_{i}}{x_{i}}}{\frac{y_{j}}{x_{j}}} = K_{i}/K_{j}

where,    \alpha = relative volatility of more volatile component i

               y_{i} = vapor-liquid equilibrium concentration of component i in the vapor phase

               x_{i} = vapor-liquid equilibrium concentration of component i in the liquid phase

                y_{j} = vapor-liquid equilibrium concentration of component j in the vapor phase

                 x_{j} = vapor-liquid equilibrium concentration of component j in the liquid phase

So, when \alpha > 1 then separation by distillation is easier in nature.

Thus, we can conclude that in order to separate the components of a binary mixture, the relative volatility should be greater than unity.

The combination of a carbonyl group and a hydroxyl group on the same carbon atom is called a ________ group.
alukav5142 [94]

Answer:

d. carboxyl

Explanation:

The presence of carbonyl group (>C=O)) and a hydroxyl group ( (−OH) on the same carbon atom is called a "carboxyl" group. A carboxyl group is represented as COOH and acts as the functional group part of carboxylic acids.

For example:

  • Formic acid or Methanoic acid (H-COOH)  
  • Butanoic acid (C3H7-COOH)

Hence, the correct option is "d. carboxyl ".

Which of the following is not a concentration unit (a) 1 molar (b) 1 equivalent (c) 1% by mass (d) 1 molal
musickatia [10]

Answer:

(b) 1 equivalent  

Step-by-step explanation:

Concentration is the relative amount of a substance in a given volume or mass of something else.

An equivalent is not a concentration, because it is just a mass —the mass of a substance needed to react with or supply one gram of hydrogen.

(a) is <em>wrong</em>. 1 M means that there is 1 mol of a substance in 1 L of solution.

(c) is <em>wrong</em>. 1 % by mass that there is 1 g of a substance in 100 g of the mixture.

(d) is <em>wrong</em>. 1 m means that there is 1 mol of a substance in 1 kg of solvent.
