Boron carbonate decomposes into boron oxide and carbon dioxide. how many moles of co2
are produced when 5.0 mol of boron carbonate decomposes completely?
1 b2(co3) - 1 b,0,3 co,
o
a. 15 mol
ob. 1.67 mol
o
c. 5 mol
o d. 8 mol

15 moles

The decomposition of boron carbonate is given by the equation;

B₂(CO₃)₃(s) → B₂O₃(s) + 3CO₂(g)

Moles of boron carbonate decomposed is 5.0 mol

To find the moles of CO₂ produced we are going to use the mole ratio.

Mole ratio of B₂(CO₃)₃ to CO₂ is 1 : 3

Therefore;

Moles of CO₂ = Moles of B₂(CO₃)₃ × 3

                      = 15 mol

Therefore, 15 moles of CO₂ will be produced
