For the reaction of C2H4(g) with O2(g) to form CO2(g) and H2O(g), what number of moles of CO2 can beproduced by the reaction of 0.480 mol C2H4 and 1.17 mol O2

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

it means there are 3 atoms of oxygen
