Answer:
(a) The molecules begin to move farther apart decreasing their intermolecular forces and they escape the liquid state to enter the gas state.
Explanation:
As we put tea pot full of water on stove the heat transfer starts from surface of tea pot to the closest water molecule near the surface of tea pot, after becoming hot the water rises up and cooler water comes down. When water begins to boil their intermolecular forces begin to decrease and they start to convert in gaseous or vapor state.
The answer is B. Each chlorine has three non-bonded pairs and one bonded pair of electrons.

Answer:
C.)Recycled bottles and containers are used to produce lumber products that can be used as an outdoor building material.
Explanation:
There are two molecular orbitals in the CH2O or formaldehyde. These are designated by the two types of bonding involved. The first is the sigma bonding. It is the head-on overlap of electrons of the C and H atoms. The second molecular orbital is formed from the pi orbital bonding. This is a sideway overlap of electrons between C-O bonding.
