If 33.4 g of CO2 is produced in the reaction of C2H2 with O2 to form CO2 and H2O how many grams of H2O are Produced in this reaction

Explanation:

2C₂H₂ + 5O₂ = 4CO₂ +  2H₂O .

CO₂ formed in moles = 33.4 / 44 = .76 moles

4 moles of CO₂ is formed by 2 moles of C₂H₂

.76 moles of CO₂ is formed by .38 moles of C₂H₂

.38 moles of C₂H₂ were present initially

2 moles of C₂H₂  produces 2 moles of water

.38 moles of C₂H₂  produces .38  moles of water

water produced = .38 moles

= .38 x 18 = 6.84 grams of water .

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
