How much H2O is produced when 40000 g of
C2H, burns completely?
Answer in units of g.

Sagot :

evasol

Answer:

1200g H20.

Explanation:

Write out the balanced equation... when an organic compound is burned, like C2H2, it is burned in oxygen (O2) and produces Water and Carbon Dioxide (CO2)

so 2C2H2 + 5O2  =  2H2O  + 4CO2

now that you have a balanced equation just convert to moles and solve

2000g C2H2 * 1mol C2H2 / 30gC2H2 * 2mol H2O/2mol C2H2 * 18gH2O/1molH20 = 1200g H20.
