Question

When x gram of carbon are heated with y gram of oxygen in a closed vessel no solid residue is left behind then show that y/x is greater than or equal to 1.33?

Answer 1

Answer:

Hello

understand this,

If one mole of each reactant is used in the reaction then,

C + O2 gives CO2

12gm 32 gm 44 gm

(X) (Y)

therefore,,

according to the question,if no residue is left behind then CO2 will escape as a gas

SO,,

X/Y=12/32

=0.375

AND

Y/X=2.6667 ======= which is greater number

which is approximately equal to 2.67
