Question

How many moles of Carbon dioxide are produced when 4.5 mol of Boron carbonate decomposes completely?

Answer 1

n CO2 = 13.5 mol

Step-by-step explanation:

balanced reaction:

• B2(CO3)3 → B2O3 + 3CO2

∴ n B2(CO3)3 = 4.5 mol

⇒ n CO2 = (4.5 mol B2(CO3)3)*( 3 mol CO2 / mol B2(CO3)3 )

⇒ n CO2 = 13.5 mol
