Ans 1 :

Elements are pure substances that are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are in fixed proportions. There are nearly 118 elements of which nearly 94 occur naturally on Earth.

Ans 2 :

For example, water is a compound. Water has the chemical name H2O because it contains two hydrogen atoms and one oxygen atom chemically bonded together. H2O is a molecule, and because it contains two different types of atoms, water is also a compound.

Answer 1

An element is a pure substance made up of only one type of atom, characterized by its unique chemical properties and atomic number. In contrast, a compound is a substance composed of two or more different elements chemically bonded together in fixed ratios.

Ans2

Water (H₂O) is an example of a compound. It is classified as a compound because it consists of two different elements, hydrogen and oxygen, chemically bonded together in a fixed ratio. In water, two hydrogen atoms combine with one oxygen atom to form a stable compound with distinct chemical and physical properties that differ from those of its constituent elements.

Answer 3

A mixture is a combination of two or more substances in which each substance retains its own chemical properties. Unlike compounds, the substances in a mixture are not chemically bonded, and their proportions can vary. Mixtures can be homogeneous (uniform composition) or heterogeneous (non-uniform composition).

Example: Trail mix is a heterogeneous mixture consisting of various components like nuts, dried fruits, and chocolates. Each component retains its individual properties, and you can easily see and separate them in the mixture.

Answer 1:Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions.

Answer 2:An example of a compound can be sodium chloride (NaCl) and it is classified as a compound because Common salt is made up of Sodium and chlorine atom.

Answer 3:The characteristics of a mixture are:

Mixtures have no fixed composition.

To form mixture energy is neither produced nor evolved.

The mixture has no fixed melting points and boiling points.

Mixture retains the properties of its components.

Components of mixtures can be separated by simple physical methods

An element is a chemical bond of two or more atoms of the same kind, whereas a compound is a chemical bond of two or more elements of different kinds.

Ans 2:

• Sulphur dioxide/oxide/trioxide:

Sulphur oxide is classified as a compound because its formula is SO², it consists of two or more elements of the same kind. Similarly, sulphur oxide 's formula is SO³, and sulphur trioxid's formula is SO. Sulphur oxide's formula is SO because it contains one element of sulphur and one element of oxygen, and sulphur trioxide's formula is SO³ because is contains one element of sulphur and three elements of oxygen. However, sulphur dioxide is classified as a compound because it consists of elements of different kinds.

Mixture:

A mixture is a material made up of two or more, different chemical substances which are not chemically bonded.

A mixture has no fixed composition.
