Is water a mixture or compound? Give 3 reasons?
Answers
Answer: Hey mate here you go
Water have totally different property than its constituents hydrogen and oxygen. 3) Compounds are formed by chemical bonding between the elements while a mixture doesn't involve formation of a chemical bond. Now if you observe, water is formed by chemical bonding i.e. covalent bonding between hydrogen and oxygen.
Explanation:
Answer:1) In water Hydrogen and Oxygen combine in the ratio of 1:8. Thing which is to be noted here is hydrogen and oxygen are not substances, they are elements.
2) Compounds have totally different properties than its constituents i.e. elements. Mixture has same property than its constituents. Water have totally different property than its constituents hydrogen and oxygen.
3) Compounds are formed by chemical bonding between the elements while a mixture doesn't involve formation of a chemical bond. Now if you observe, water is formed by chemical bonding i.e. covalent bonding between hydrogen and oxygen.
4) Mixture may or may not involve chemical reactions between its constituents but compounds are formed by the chemical reaction between its constituents. Hydrogen + Oxygen = Water.
5) Since compound has chemical bonding between its constituents its constituents can be separated only by chemical or electrochemical reactions while components of mixture can be separated by physical methods like handpicking , winnowing, etc. The constituents of water i.e. hydrogen and water are separated by 'electrolysis of water' the technique which we study in higher classes.
These are the reasons why water is a compound and not a mixture.
