Question

calculate the amount of carbon dioxide that could be produced when ?1 mole of carbon is burnt in air​

Answer 1

Explanation:

(i) 1 mole of carbon is burnt in air.

C+O

2

→CO

2

1 mole of C produces 1 mole of CO

2

which corresponds to 44 g of CO

2

.

(ii) 1 mole of carbon is burnt in 16 g of dioxygen.

16 g of dioxygen corresponds to

32

16

=0.5 moles.

Here, dioxygen is the limiting reagent.

It will produce 0.5 moles of CO

2

which corresponds to 0.5×44=22 g of CO

2

.

(iii) 2 moles of carbon are burnt in 16 g of dioxygen.

16 g of dioxygen corresponds to

32

16

=0.5 moles.

Here, dioxygen is the limiting reagent.

It will produce 0.5 moles of CO

2

which corresponds to 0.5×44=22 g of CO

2

.

Answer 2

Answer:

$\boxed {answer : -}$

So that, you can calculate the molar mass of the compound. We can conclude from the equation when 1 mole of carbon burnt in 1 mole of dioxygen (molecular mass = 32), gives rise to 1 mole of carbon dioxide (molecular mass=44). Now according to the question only 16g of dioxygen is available for the reaction. = 0.5 moles.
