What is true of a molecule? A. All molecules of a compound have the same properties. B. Each molecule of a compound has different properties. C. All molecules of a compound have one type of atom. D. Each atom of a molecule is the same.

A. or C. (most likely C.)

Explanation:

All molecules of a compound have the same properties. ... All molecules of a compound have one type of atom.

Jeez, they r both truego with A. or C.

Hope this helps!

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

"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"
