A non-metal A is an important constituent of our food and forms two oxides B and C. Oxide B is toxic whereas C causes global warming
(a) Identify A, B and C
(b) To which Group of Periodic Table does A belong?
Answers (1)
Ans.
(a) Non-metal A is carbon.
Two oxides are carbon monoxide and carbon dioxide.
Oxide B is toxic whereas C causes global warming
So B is carbon monoxide (CO) and C is carbon dioxide (CO2)
(b) Atomic weight of C = 6
Electronic configuration of C is 2, 4.
It is present in 14th group (10 + valence electrons), i.e., IV A of the periodic table.
