     H-C- H    methane structure 
         H

  HCl    react with CH2Cl2  to form  methane (CH4) and chlorine gas(Cl2)
that is,

2HCl(g)  + CH2Cl2(l)  = CH4 (g) +2Cl2 (g)

Boron carbonate decomposes into boron oxide and carbon dioxide. How many moles of CO2
Paul [167]
<h3>Answer:</h3>

15 moles

<h3>Explanation:</h3>

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
