Answer:

Carbon and oxygen react in the ratio 3:8 by mass to form Carbon dioxide.

hence the required reaction is;

C+O2--> CO2

carbon: oxygen = 3:8

due to law of constant proportion , the mass ratio in which the reactants react will remain constant .

Carbon -> 9 g

Oxygen-> ?

C:O2-> 3:8

9:O2-> 3:8

9\O2 = 3\8

Mass of required oxygen

(9\3)×8

3×8

24 g

Carbon->9 g

Oxygen->24 g

hope it will help you

It is given that,

It is given that,C + O2 ---> CO2

in carbon dioxide, the ratio of mass of carbon to oxygen is 3 : 8.

Let x grams be the mass of the oxygen that would be required to react completely with 6 grams of carbon. According to the law of constant proportion,

(6/x) = (3/8)

=> x = 16 g

Therefore, 16g of oxygen is required to completely react with 6 gram of carbon.

Since you now know the reaction for the formation of CO2, work on it yourself and let us know if you face any issues.
