Which problem does this model of the solar system solve? A. The real-life hrough a telescope.
C. The real-life solar system is too fragile to manipulate by hand.
D. The real-life solar system is too large to fit in a laboratory.​

where is the option B

you gave a, c, d. options but what happened to b?

"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"

your answer would be “dry”
