Explain why , water is a compound and not a mxture .

Explanation

Water is considered a compound because of the following reasons :
(i) Water cannot be separated into its constituents , hydrogen and oxygen , by the physical methods (such as filtration , evaporation , distillation , sublimation , magnet , etc).
(ii) the properties of water are entirely diffferent from those of its constituents , hydrogen and oxygen , for example , water is a liquid whereas hydrogen and oxygen are gases , water does not burn whereas hydrogen burns ,water does not suopport combustion whereas supports combustion .
(iii) Heat and light are given out when water is prepared by by burning hydrogen in oxygen .
(iv) the compostion of water is fixed , It contains hydrogen and oxygen combined togehter in a fixed proportion of 1:8 by mass, It has a definite formula ,`H_(2)O`
(v) Water has a fixed boiling point of `100^(@)` C under standard almooshe3ric pressure.
