ABC are mixtures but D is a pure substance
To determine which of the given options is a pure substance, we need to understand what a pure substance means. A pure substance is a substance that contains only one type of particle, either an individual element or a compound. It cannot be separated into other substances by physical means.
Let's analyze the options:
A) Chocolate milk: Chocolate milk is a mixture of milk and chocolate syrup. It contains two different components, so it is not a pure substance.
B) Orange juice: Orange juice is a mixture of water and the juice extracted from oranges. It contains multiple components, so it is not a pure substance either.
C) Seawater: Seawater consists of water and various dissolved substances, including salts and minerals. It is also a mixture, so it is not a pure substance.
D) Hydrogen peroxide (H2O2): Hydrogen peroxide is a compound made up of hydrogen and oxygen in a specific ratio (two hydrogen atoms and two oxygen atoms). It contains only one type of particle and cannot be separated into simpler substances. Therefore, hydrogen peroxide is a pure substance.
Based on this analysis, the correct answer is D) Hydrogen peroxide (H2O2).
