What is the maximum number of moles h2 that can be produced by the reaction of 3. 00 mol of ni with 4. 50 mol of hcl according to the equation: ni 2hcl → nicl2 h2.

false

because it does not have the potential to be entirely used up

"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"
