Question

Identify the limiting reagent if 1 mole of carbon burns in 16 g of air

Answer 1

Answer:

when 1 mole of carbon is burnt in 1 mole(32 g) of air(dioxygen) ,then according to chemical equation (1) 1mole(44 g) of carbon dioxide is produced. (iii) According to the question, only 16 g of dioxygen is available. It is a limiting reactant

Answer 2

Answer:

the limiting reagent is 3:4

Explanation:

molar mass of 1 mole carbon = 12g

air = 16g

then,

12:16 = 12/16

= 3:4
