Question

Tow elements X and Y combine in a ratio of 3.8 if mass and the compound Z is one of the essential components of photosynthesis to take place if Z is also one one of the green house gases then (¡) identy X,Y and Z (¡¡) write the electronic configuration of X and Y​

Answer 1

(a) ‘X’ and ‘Y’ are C (carbon) and O (oxygen). These combine in ratio of 12:32 i.e., 3:8. ‘Z’ is CO2(carbon dioxide) (b) ‘X’ is carbon (atomic number 6) so its electronic configuration is 2, 4. ‘Y’ is oxygen (atomic number 8) so its electronic configuration is 2, 6.
