Another difference between compounds and mixtures of elements is the ease with which the elements can be separated.

What kind of compounds do elements react with?

Which is the best example of a compound?

Examples of Compounds: 1. Water – Formula: H 2 O = Hydrogen 2 + Oxygen Two atoms of the element Hydrogen combine with one atom of Oxygen through a covalent bond to form water.

How are elements separated from a chemical compound?

The individual components of a mixture can be physically separated from each other. Chemical compounds are very different from mixtures: The elements in a chemical compound can only be separated by destroying the compound.

What are the different types of compound words?

Types of Compound Words There are three types of compound words; Closed Compound words: These words are written as a single word, such as haircut, newspaper, grandmother, etc. Open Compounds: Compound words that are written as separate words such as high school, living room, school bus, etc.
