Sir par water to do cheej sai banaa h naa

[@primarystudentankitanshika2373]

Water = H²O
Isme 2 H aur ek O hoga ..
It means pure water m same aise hi molecules honge ( 2H and 1 O )
So .... They are similar and hence it is pure substance ..
Hope it helps ☺️

Hello sir

[@davieblastviros5279]

What about H2O

[@jarnail41]

It's pure because it is a compound(water), it is made of one molecule which contains one atom of oxygen and two of hydrogen, it's combined by chemical reaction, it has a fixed proportion, and it has a fixed set of physical and chemical properties. Hence, it is a pure substance.
