Question

calculate amount of CO2 produced when 2 moles of 'c' react with 60g O2? Find amount of unreacted reactants?​

Answer 1

Answer:

(ii) 1 mole of carbon is burnt in 16 g of dioxygen. (iii) 2 moles of carbon are burnt in 16 g of dioxygen. Medium ..

Answer 2

Answer:

(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

.

(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

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

16 g of dioxygen corresponds to
