<span>As the moisture-rich air approaches the mountain, it rises and cools, and water molecules in the air combine to form small drops. The process where water vapor becomes a liquid is called condensation. </span>
Answer: 4
Explanation: Your counting 4 for each interval. 9+4 =13 13+4 =17 17+4 =21 and so on.
The most difficult concept will be the concept of patient drug tolerance because there are many drugs that have different side effects for different patients. Therefore, it is necessary to understand the response of certain drugs to different patients. This will help avoid wrong drug combinations. This can cause side effects.
To learn more about this concept, you need to do your homework on these different drugs and the tolerance reactions you may experience, and attend some drug tolerance seminars, where the speaker will give you more ideas . And a further explanation of the concept.
Another topic in chemistry that is most tough to understand is moles. We can understand this concept by understanding the fact mole is an amount of a substance which may be atoms, molecules, ions, etc which have exactly 6.02214076 * 1023 'elementary entities' of the substance.

Answer:
We are considering an Allene molecule here, CH2CCH2. To answer your question, NO, they don't have to lie on the same plane. The spatial arrangement between them is that the center carbon that forms these pi bind in the left and right are PERPENDICULAR to each other.
Explanation:
We see here that The terminal carbons are sp2 hybridized, and form three σ-bonds each which means that each terminal carbon has one unhybridized p-orbital. The central carbon atom is sp hybridized, and forms two σ-bonds which means it has two unhybridized p-orbitals. For better understanding, let's call these two orbitals px and py. Summarily, These orbitals are perpendicular to each other
Neon is a noble gas, so is very stable and has an atomic number of 10. So it has 10 protons and 10 neutons. So no it does not need to bond.
