What are homogeneous mixtures of metals commonly called?.

"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"

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
