Which of the following is pure substance?
Chocolates milk
Orange juice
Seawater
Hydrogen peroxide
I'm not sure what's the right answer!!
LOL, is it the filtered orange juice ?
The answer is the only chemical element mentioned here, Hydrogen peroxide.
To determine which of the following is a pure substance, we need to understand what a pure substance is. A pure substance is a form of matter that has a constant composition and distinct properties. It is not mixed or contaminated with any other substances.
Now, let's analyze each option:
1. Chocolate milk: Chocolate milk is a mixture of milk and chocolate syrup. Since it consists of two or more substances that are combined, it is considered a mixture rather than a pure substance.
2. Orange juice: Orange juice generally contains water, pulp, and natural sugars from the oranges. It is also considered a mixture since it is composed of different substances.
3. Seawater: Seawater is a mixture of water and various dissolved minerals and salts, such as sodium chloride (salt). It is a combination of different substances and not a pure substance.
4. Hydrogen peroxide: Hydrogen peroxide (H2O2) is a chemical compound composed of two hydrogen atoms and two oxygen atoms. It has a definite composition and specific properties, making it a pure substance.
Therefore, the correct answer from the given options is hydrogen peroxide. It is the only option that qualifies as a pure substance.
