Neutrons are in the nucleus of the atom. A neutron has a) A positive charge
b) No charge
c) A negative charge
d) Twice as much positive charge as a proton

B. (No charge)

Explanation:

Protons have a positive charge, electrons have a negative charge.

Neutrons are neutral and therefore have no change.

"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"
