Answer to Question #117683 in General Chemistry for Ella

Question

Boron carbonate decomposes into boron oxide and carbon dioxide. How many moles of CO2 are produced with 1.67 mol of boron carbonate decomposes completely? Write your answer out to the tench place. B2(CO3)3 = B2O3 + 3CO2

Answer 1

B2(CO3)3 = B2O3 + 3CO2

n (B2(CO3)3) = 1.67 mol 

According to the equation:

n (CO2) = 3 * 1.67 = 5.01 mol or 5.0 mol
