Answer:

moles CO2 = 0.065 moles

Explanation:

mole = 6.022 E23 molecules.....Avogadro

∴ molecules CO2 = 3.9 E22 molecules

⇒ moles CO2 = (3.9 E22 molecules CO2)×( moles CO2/ 6.022 E23 molecules CO2)

⇒ moles CO2 = 0.065 moles

When water vapor condenses, how much heat energy will be released into the atmosphere?

Leona [35]

When water vapor condenses, 2260 joules/gram heat energy will be released into the atmosphere.

To add, heat energy (or thermal energy or simply heat) is defined as a form of energy which transfers among particles in a substance (or system) by means of kinetic energy of those particles. In other words, under kinetic theory, the heat is transferred by particles bouncing into each other.
