Question

if 10g of carbon react with 12g of oxygen find the amount of carbon dioxide produced​

Answer 1

C+02-----------CO2

Here,it is clear that 1 mole of carbon reacts with 1 mole of oxygen and forms 1 mole of Carbon dioxide.

Or say that,12 g of CO² with 32g of O² and forms 44 g of CO²

But, weight of O² is given just 16g. So, O² is

limiting reagent.

Now,32 g of O² forms 44 g of CO².

So,1 g of oxygen forms 44/32=11/8 g of CO²

So, 16g if O² forms 11/8×16² 22 g of CO²

Hence,weight if CO² =22g
