In the given three-dimensional molecular structure, the differently colored spheres represent different types of atoms. Write a molecular formula for this molecule.

"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"

b.

the accuracy of the data.

answer carbon and three oxygen atoms;
