Chemistry Notes P 12 and P 32

[FlameBlazer69]

My chem teacher gave us this PDF file which has all the important notes of all chapters. I think it would be useful to everyone so download it . When you open the file it'll ask for a password. The password is ri5uv65. Hope it helped

(part 1 )see in the first line its given that 175 cm3 of o2 was used and in the last line its given that 25 cm3 of o2 is left
(unreacted) Therefore, the vol of o2 reacted is 150 cm3
(Part 2) the gas formed after cooling is 125 cm3 (given in ques) so it will have unreacted oxygen and the co2 formed
125cm3-25cm3=100cm which is the vol of co2 formed
