Answer:
1.
MIXTURES
Silicon dioxide is a pure substance. It is a compound. Sand and stones form a heterogeneous mixture.
2.
MIXTURES
Basically glass is the homogenous mixture of the silicates of various alkaline metals of non-crystalline and transparent or less transparent substances. Ordinary glass is manufactured by the composition of various substances like silica, bleaching powder, oxides of alkaline metals, calcium oxide (lime) etc.
3.

✯What is a Mixture?
In chemistry, when two or more substances mix with each other without participating in a chemical change, the resulting substance is called a Mixture.
✯General Properties of Mixtures
Mixtures are made up of two or more substances that are not chemically combined with each other. The properties of mixtures are listed below.
- The components of a mixture each keep their original properties.
- The separation of components can be easily done.
- The proportion of the components is variable.
✯What is a Compound?
When two or more elements chemically combine in a fixed ratio by mass, the obtained product is known as a compound
✯General Properties of Compound
☆Molecular and Ionic Compounds
Water is a molecular compound; it is made up of electrically neutral molecules , each containing a fixed number of atoms. Sodium chloride is an ionic compound; it is made up of electrically charged ions that are present in fixed proportions and are arranged in a regular, geometric pattern (called crystalline structure) but are not grouped into molecules. The atoms in a compound are held together by chemical bonding
✯What is an Element?
a species of atoms all atoms with the same number of protons in the atomic nucleus. A pure chemical substance composed of atoms with the same number of protons in the atomic nucleus.
✯main elements?
The Five Base Elements are Fire, Earth, Metal, Water, and Wood. In a state of continuous interaction and flux with each other these elements are known as different types of energy. Not only does The Five Elements mean Fire, Earth, Water, Metal, and Wood. We also apply to motion, transition, and growth.
