calculate the amount of carbon dioxide that could be produced when
i)1 mole of carbon is burnt in air
ii)1 mole of carbon is burnt in 16g of dioxygen
iii)2 moles of carbon are burnt in 16g of dioxygen
Answers
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
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:
1, ans is 44
Explanation:
Because we use formula of no. Of moles which is
No. Of moles = mass/molar mass
As we have 1mole given and find out amount of co2 then its molar mass will be 44.
Mass will be equal to 1*44=44
