Quick chemistry question worth 15 points will mark brainliest!

if the amount of energy required to break bonds in the reactants is more than the amount of energy released in forming bonds in the products, the chemical reaction is endothermic.

true or false

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"
