1 mole = 6.22 x 10^23 molecules (Avogadro's number)
15 moles x (6.22 x 10^23) = 9.33 x 10^24 atoms
Answer: The derivative of a constant term is always 0. So the acceleration of the body would be zero. Hence, the acceleration of a body moving with uniform velocity will always be zero.
Hope this helps :) :)
With the lack of these 3 factors you throw off your health triangle and your health is unbalanced. When you eat well you can get vitamins such as "E" and "C". These vitamins help build up immune cells that help build the immune system. When a person does not get enough sleep that person is more open to viruses and bacteria. Getting the recommended vaccines help you to fight off possible diseases or illnesses. They make you immune system stronger so you can be healthier.
Ionic or electrovalent compounds support the theory of ionic bonding because they are compounds composed of charged particles formed when an atom gains or loses electrons.
Electrovalent compounds posses:
- High boiling and melting points.
- Form crystals.
<h3>What is ionic bonding?</h3>
This is the transfer of valence electrons from metals to non metals to form ionic compounds. It also refers to a chemical bond formed between two ions with opposite charges.

Answer:
a. Hydrocarbons have low boiling points compared to compounds of similar molar mass.
b. Hydrocarbons are hydrophobic.
d. Hydrocarbons are insoluble in water.
Explanation:
As we know that the hydrocarbons is a mix of carbon and hydrogen. In this the availability of the electronegative atom is not there that shows there is no bonding of the hydrogen plus it is dissolved. Also, the hydrocarbons is considered to be a non-polar but as compared to the water, water is a polar
In addition to this, the strong bond is no existed that shows the lower boiling points
Therefore option A, B and D are right
