Question

calculate the amount of CO2 that could be produced when 1 mole of C is burnt in air

Answer 1

Answer:

Calculate the amount of co2 that could be produced when 1). 1 mole of carbon is burnt in air 2). 1 mole of carbon is burnt in 16 gram of o2 3). 2 moles of carbon is burnt in 16 gram of o2

i)I mole of Carbon burnt in air

C + O2 –> CO2

1 mole of carbon produces 1 mole of CO2 which is 44g of CO2

ii) 1 mole of carbon is burnt in 16g of dioxygen

32g of O2 = 44g of CO2

1g of O2 = 44/32 CO2 (Dioxygen is limiting reagent)

16g of 02 = 4/32*16 = 22g of CO2 in one mole

iii) 2 moles of Carbon burnt in 16g of dioxygen

16g of dioxygen is available and thus it can combine with 0.5 mol of carbon to

give 22g of CO2

Hope this help you
