Question

Carbon and oxygen react in the ratio 3:8 to form Carbon dioxide. What mass of oxygen is required to react with Og of carbon? Name and state the relevant law.​

Answer 1

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
