Question

3 grams of carbon dioxide is completely burnt in large excess of oxygen then the weight of carbon dioxide formed is

Answer 1

~> 1 mol of C react with 1 mol of O2 to form 1 mol of CO2. So, here clear that amount carbon limit the reaction as it’s work here as liming reagent.

~> 12 gm of C react with 32 gm of O2 to form 44 gm CO2.

~> By following unitary method we get that 0.5 mol of C will produce 0.5 mol of CO2

#) i.e. 22 gm of CO2.

Hope It helps You Out =)

Thanks.. (^^)
