Answer 1

The correct answers to the given questions are:

Q1: a) Decantation

Q2: a) Mixture

Q3: d) Adding milk to water.

What is Decantation:

• The process of decanting involves separating the liquid layer at the top from the layer of solid or liquid below in order to separate liquid from solid and other immiscible (non-mixing) liquids. After pouring out the top layer, the mixture can be tilted to complete the process.

• Example: Water and oil: Water floats on top of the oil. Oil can be poured off of water after letting an oil and water mixture sit for a while. The water and oil can be separated using a separatory funnel. Water and dirt: Decantation is one technique for cleaning murky water.

What is a mixture:

• A mixture is what results from the random mixing of two or more substances when no chemical reaction takes place. A mixture can be easily divided.

• A mixture would be salt in a jar with an undetermined amount of sugar added.

Question 3:

• Option D) is correct because when milk is added to water, it can still be separated physically via filtration. It is a mixture since there has been a physical reaction between the ingredients but no new substance has been created or their molecules have changed.

• A mixture is any material or combination of components that do not undergo any chemical transformation or change in the physical structure of the molecules. This definition is exactly met in the scenario at hand, making it a combination.

The given options for question one are incorrect so the correct option is Decantation.

For question 2 the complete question is

For question 3 the complete question is Which one of the following will result in the formation of a mixture?

A) Crushing of a marble tile into small particles B) Breaking of ice cubes into small pieces

C) Adding sodium metal to water wrong

D) Adding milk to water.​
