Calculate the amount of carbon dioxide t...

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 16 g of dioxygen.

Text Solution

Verified by Experts

`{:(C_((s)),+,O_(2(g)),rarr,CO_(2),),(1 mol,,1 mol,,1 mol,),(,,32 g,,44 g,):}`
(i) According Reaction, the complete combustion of 1 mol carbon with air and creat `44 g CO_(2)`.
(ii) For complete combustion of 1 mole carbon 32 g dioxygen gas is consumed but here, only 16 g dioxygen is present. So, dioxygen is a limiting reagent. So, `22 g CO_(2)` gas is formed by 16 g dioxygen.
(iii) According to above example dioxygen gas is limiting reagent. So, 0.5 mol `CO_(2)` gas formed 16 g dioxygen.
