1) Amount of carbon dioxide:
Description
According to 1st question -
1 mole of carbon is burnt in air (dioxygen) to produced 1 mole of carbon dioxide. In this reaction carbon is in limited quantity so, it is limiting reagent
We know, 𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑚𝑜𝑙𝑒 =MassMolar Mass
𝑆𝑜 𝑡ℎ𝑒 𝑎𝑚𝑜𝑢𝑛𝑡 𝑜𝑓 CO2 𝑝𝑟𝑜𝑑𝑢𝑐𝑒𝑑=44×1=44 g
2) Amount of carbon dioxide:
Description
According to 2nd question:
1 mole of carbon is burnt in 16 g of dioxygen means 0.5 mole of dioxygen
Number of mole=MassMolar mass
So, have dioxygen is a limiting reagent
So,0.5 mole of O2 react with 0.5 mole of CO2
So the amount of CO2 produced =no.of mole × Molar mass=0.5×44=22 g
3) Amount of carbon dioxide:
Description.
According to 3rd question :
2 moles of carbon are burnt in 16 g of dioxygen means 0.5 mole of dioxygen.
𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑚𝑜𝑙𝑒=MassMolar Mass
Here, dioxygen is limiting reagent
So, the amount of CO2 produced by 0.5 mole of O2=0.5×44=22 g
Final answer:
(i) Amount of carbon dioxide is 44 g
(ii) Amount of carbon dioxide is 22 g
(iii) Amount of carbon dioxide is 22 g
