Is lemonade pure substance or mixture?

Lemonade is a mixture. Here's why:

* Pure substance: A pure substance is made up of only one type of molecule. Examples include water (H₂O), sugar (C₁₂H₂₂O₁₁), and salt (NaCl).

* Mixture: A mixture is made up of two or more substances that are physically combined but not chemically bonded. The substances in a mixture retain their individual properties.

Lemonade is a mixture because it's made of:

* Water: A pure substance.

* Sugar: A pure substance.

* Lemon juice: A mixture of water, citric acid, and other compounds.

The ingredients in lemonade are not chemically bonded together, and you can separate them using physical methods (like evaporation).
