For the reaction represented by the equation 2a + 2H20 --> 2NaOH + H2,
how many grams of sodium hydroxide
are produced from 68.7 grams of sodium
with an excess of water?

"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"

just did the assignment and the answer was #1 +2 n

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
