What is the 3-dimensional orientation of a sublevel known as?
RoseWind [281]

The 3-dimensional orientation of a sublevel is known as atomic orbital.

In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.

Each sublevel has an orbital and it is oriented differently in 3-dimensional space.

The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.

when 32.4 g of water vapor condenses, how much heat is given off? The heat of vaporization for water is 40.67 kj/mol
egoroff_w [7]
When a water vapor condenses, heat is being released from the process. This heat is called latent heat of vaporization since the phase change happens without any change in the temperature. This value is constant per mole of a substance as a function of pressure and temperature. For this problem, we are given the heat of vaporization at a certain T and P. We use this value to calculate the total heat released from the process. We calculate as follows:

Total heat released: 32.4 g ( 1 mol / 18.02 g ) (40.67 kJ / mol) = 73.12 kJ

Therefore, 73.12 kJ of heat is released from the condensation of 32.4 g of water vapor.

Explain, in terms of particles, why liquid<br> iodine does not conduct electricity.
drek231 [11]

Answer:

Because iodine is a liquid, it has no melting point. Iodine is not an electrical conductor because each molecule consists of two iodine atoms connected by a covalent bond that cannot be stimulated sufficiently to transmit electrical energy.
