Nitrogen And Oxygen - 2


1. Carbon dioxide is produced when dilute nitric acid reacts with carbonates and bi-carbonates.


2. Ozone is an allotropic form of sulpher.


3. Nitric acid reacts with hydrogen sulphide to give a suspension of sulphur.


4. H2+Cl2 ------------------->2HCl is an example of Reducation reaction.


5. The binary compounds of other elements with oxygen are called oxides.
