Water is an example of a(n).
A atom
B compound
C mixture
D element
The Correct Answer and Explanation is :
The correct answer is B) compound.
Water (H₂O) is a compound because it consists of two or more elements chemically bonded together in a fixed ratio. In the case of water, each molecule is made up of two hydrogen (H) atoms bonded to one oxygen (O) atom. Compounds are formed when atoms of different elements combine through chemical bonds, and the properties of the compound are different from the properties of the individual elements that make it up.
To understand why water is a compound, it’s important to differentiate between atoms, elements, compounds, and mixtures:
- Atoms are the basic building blocks of matter. An atom is the smallest unit of an element, and it retains the properties of that element. Water is not an atom because it is made up of multiple atoms.
- Elements are pure substances made up of only one type of atom. Each element is represented by a chemical symbol, such as H for hydrogen and O for oxygen. Water is not an element because it is made from two elements, hydrogen and oxygen, combined in a specific ratio.
- Mixtures are combinations of two or more substances that are not chemically bonded. Each substance in a mixture retains its individual properties. For example, saltwater is a mixture because the salt and water remain separate, even though they are physically combined. Water is not a mixture because hydrogen and oxygen are chemically bonded in a specific way.
- Compounds, like water, are pure substances that consist of two or more elements chemically bonded together. Water has a fixed molecular structure (H₂O), where the ratio of hydrogen to oxygen is always the same. This chemical bonding gives water distinct properties, such as its ability to dissolve many substances and its unique physical characteristics.
Thus, water is a compound because it is made of different elements (hydrogen and oxygen) that are chemically bonded together.
