Acetylene gas (C2H2) used in welding, pro- duces an extremely hot flame when it burns in pure oxygen according to the reaction
2 C2H2(g)+5 O2(g) −→ 4 CO2(g)+2 H2O(g) .
How much CO2 is produced when 20000 g of C2H2 burns completely?

Respuesta :

transitionstate
Answer:
             67692 g of CO₂

Solution:

Balance Chemical Equation is as follow,

                            2 C₂H₂  +  5 O₂    →    4 CO₂  +  2 H₂O

According to equation,

         52 g ( 2 mole) Acetylene produces  =  176 g (4 mole) of CO₂ 
So,
              20000 g Acetylene will produce  =  X g of CO₂

Solving for X,
                          X  =  (20000 g × 176 g) ÷ 52 g

                          X  =  67692 g of CO₂
