How many grams of carbon dioxide would be formed if 38.9 g of c2h2 reacted completely with oxygen

131.7 grams of carbon dioxide would be formed

Explanation:

2C₂H₂ + 5O₂ = 4CO₂ + 2H₂O

m(CO₂)/{4M(CO₂)} = m(C₂H₂)/{2M(C₂H₂)}

m(CO₂)=2M(CO₂)m(C₂H₂)/M(C₂H₂)

m(CO₂)=2*44g/mol*38.9g/26g/mol = 131.7 g

131.7 grams of carbon dioxide would be formed

The correct answer which describes Jodi's error is that the movement of electrons is not always continuous.  

The movement of electrons is continuous only in the case of DC, that is, direct current, where the voltage always possesses the similar direction, so the electrons always flow from low voltage to high voltage. On the other hand, when there is AC, that is, alternate current, then the direction of the voltage gets reversed constantly. Thus, the direction of movement of the electrons is also constantly reversed, hence, their movement is not continuous.
