Answer:
Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the "universal solvent" because it dissolves more substances than any other liquid. This is important to every living thing on earth.
Answer:
The correct answer is option 3.
Explanation:
The expression of 
is given by :
![K_w=[H^+][OH^-]](https://tex.z-dn.net/?f=K_w%3D%5BH%5E%2B%5D%5BOH%5E-%5D)
![K_w\propto [H^+]](https://tex.z-dn.net/?f=K_w%5Cpropto%20%5BH%5E%2B%5D)
![K_w\propto [OH^-]](https://tex.z-dn.net/?f=K_w%5Cpropto%20%5BOH%5E-%5D)
Rise in temperature will result in more dissociation of water molecules into hydrogen ions and hydroxide ions.
With an increase in concentration of hydrogen ions and hydroxide ions value of will also increase.
Answer:
empirical formula
This also means that in one mole of iso-octane, there are 8 moles of carbon and 18 moles of hydrogen. The empirical formula is the simplest whole-number ratio of atoms in the compound. For iso-octane, the empirical formula is C4H9. Notice that the molecular formula is twice that of the empirical formula.
Answer:
Compound
Explanation:
Table sugar, or sucrose, is a compound because it's formed when two or more elements are joined together. Its chemical formula is C12H22O11, and it contains carbon, hydrogen and oxygen.
