Question

Taylor was thirsty and decided to mix up a pitcher of lemonade. She put lemon juice, water, and sugar into a pitcher and stirred it to create this wonderful new drink. How could Taylor decide if she just created a mixture or a compound?

Answer 1

Answer: Taylor created a mixture.

Step-by-step explanation:

A compound is defined as the substance which is formed when two or more different elements combine in a fixed ratio by their mass. The properties of a compound formed is different from the elements. Here, the elements cannot be separated.

A mixture is produced when two or more different substances combine but not in a fixed ratio by their mass. In a mixture, substances can be easily separated by physical methods.

In the question, it is given that Taylor has made a lemonade from lemon juice, water and sugar. She has made a mixture because the properties of individual substances remain the same and they can be easily separated from one another.

The lemonade formed is not a compound because no new substance is getting formed. Thus, Taylor created a mixture.

Answer 2

Answer is: it must be a mixture as she can separate all of the individual ingredients.

Pure substance is made of only one type of atom (element) or only one type of molecule (compound), mixtures and solutions are made from two or more types of pure substances.

Elements (for example copper, iron, sulfur) and compounds (water, sodium chloride) have definite and constant composition with distinct chemical properties.

Pure substances can be separated chemically, not physically, that is difference between pure substances and mixtures.
