Answer:different elements have different number of electrons and shells/orbits thatswhy it have different atomic mass and size.
Explanation:
The electron releases energy.
Answer:
1. C 2. B 3. A
Explanation:
1. Gay- Lussac law, states that as along as the volume is kept constant, the pressure of a fixed mass of gas is directly proportional to the temperature.
The properties it compares is; (c.) Pressure and temperature
2. Boyle's Law states that; as long as the temperature is kept constant, the volume of a fixed mass of gas is inversely proportional to the pressure.
It therefore compares; (b.) Pressure and volume
3. Avogadro's Law states that equal volumes of different gases contain the same number of molecules provided the temperature and pressure are the same.
It therefore compares; (a.) Volume and moles
According to the Bronsted-Lowry definitions, an acid is any substance that donates hydrogen ions; whereas, a base is any substance that accepts hydrogen ions.
In the first reaction, water is acting as an acid because it donates a hydrogen ions.
In the second reaction, water is acting as a base because it accepts a hydrogen ion.
In the third reaction, water is again donating a hydrogen ion so it is the acid.
In the fourth reaction, water is acting as a base by accepting the hydrogen ion from the ammonium ion.
