If water and oil are combined in a container, the resulting liquid is a(n)
a. mixture.
b. emulsion.
c. solution.
d. suspension.

The correct option is (B).

Step-by-step explanation:

Emulsion is an example of colloids in which particles of component are suspended in immiscible liquids. It is usually an suspension of two liquids which do not mix together. These liquids which do not mix together are called immiscible.

Where as mixture is made up two or more substance which are mixed together. In a mixture identity of substance remains unchanged.

Solution is defined homogeneous mixture of two or more compounds. In this one components completely get dissolves in another component.

Suspension is defined as solution where one component doesn't get dissolved in another component and forms two distinct layers when left undisturbed.

Hence ,the correct answer is option(B).

b

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
