Answer:

74.566

Explanation:

C6H6 + 02 =6CO2 + 3H2O

2C6H6 + 15O2=12CO2 + 6H2O

mm of C6H6=(12x6)+(6x1)= 72+6 =78gram/mol

mass conc = 2x78=156

mm CO2= 12+(16x2)=

12+32= 44gram/mol

mass conc of CO2 = 12x44

=  528

from The equation

156g of C6H6=528g of CO2

22.031g of C6H6=Xg of CO2

therefore, Xg=

22.031 x 528/ 156

= 74.566g

Identify the classification of milk. group of answer choices aerosol solid aerosol foam emulsion solid emulsion
kotykmax [81]

Milk is an example of solid emulsion. Hence, option D is correct.

<h3>What is emulsion?</h3>

An emulsion is defined as a colloid consisting of two or more non-homogenous type of liquids in which one of the liquid contains the dispersion of the different form of liquids.

Emulsion consist of a dispersion of two liquids that are immiscible with each other.

One of the liquids act as the dispersion medium and the other will act as the dispersed phase.

Emulsions are colloids in which both the dispersed phase and dispersion medium are liquids.

Types of Emulsion:

  1. Oil in water (O/W)
  • In this type of emulsion, the oil will be the dispersed phase and water will be the dispersion medium.
  • Example of o/w emulsion is milk.

    2. Water in oil (W/O)

  • In this type, water will be the dispersed phase and oil will be the dispersion medium.
  • Margarine is an example of water in oil emulsion.

Milk is an example of solid emulsion. Hence, option D is correct.
