Answer:
The higher the pH is, the more the hydroxide ion concentration increases and the more basic the solution becomes.
Explanation:
- When the pH of a solution is less than 7, then solution is called acidic and as the pH decreases the concentration of Hydronium ion increases.
- When the pH is about 7, then the solution is said to be neutral. On the other hand, when the pH is greater than 7, the solution is is said to be basic and as the pH increases the concentration of Hydroxide ions increases.
- Therefore, An acidic solution has a higher concentration of hydrogen ions compared to the concentration of hydroxide ions.
In diesel engines, the chemical energy in the fuel is changed to heat energy, causing the pistons to expand via mechanical energy. The mechanical energy is finally converted to kinetic energy, which is observed as the movement of the vehicle.
Answer:
The correct answer is cation. See the explanation below, please.
Explanation:
An atom with a net charge, either positive or negative, is called an ion. In the event that an atom loses an electron (or more), that is, it will have more protons than electrons, and its net charge will be positive, it will be called cation. In the opposite direction, if an atom gains electrons, it will have a negative net charge, called anion.
The answer is the third one because density is mass divided by volume so 80 divided by 10 is 8
Answer: In the chemical formula for water, the subscript for hydrogen is 2. Notice that the 2 is smaller and written slightly below the H and O. It is called a subscript because it is written ("script") "below" ("sub") the preceding letter.
