Answer:
Absorbs energy
Explanation:
As an electron in an atom moves from the ground state to the excited state, the electron absorbs energy.
Electrons moves around in permissible orbits around the nucleus of an atom.
- An electron in a certain energy level has a definite amount of energy associated with it at that level.
- When an electron in ground state absorbs energy, it moves to a higher energy level.
- When an electron in excited state loses energy, it moves to a lower energy level.
The transition of electrons from one level to another involves loss or gain of energy.
Calcium is more active because it is under magnesium on periodic table.
There are 1000 mL in a L.
12.5 L = 12.5(1000) mL = 12500 mL
12500 mL = 12.5 L
Hope this helps!
Answer: False
Explanation:
An acid is defined as the substance which looses hydrogen ion or hydronium ions when dissolved in water.
A base is defined as the substance which looses hydroxide ions when dissolved in water.
If the solution has higher hydronium ion concentration as compared to the hydroxide ion concentration, then the pH will be low and the solution will be acidic.
If the solution has low hydronium ion concentration as compared to the hydroxide ion concentration then the pH will be high and the solution will be basic.
