Answer:
Explanation:
The halogens have seven electrons in their outermost shell. Each halogen atom lacks a single electron to make their octet a complete one. Elements in the halogen group are univalent and also acceptors of electrons. They are all non-metals and oxidizing agents. The oxidizing power of the halogens decreases from top to down the group. This is why the more powerful halogens displaces a less powerful one from simple salts.
Cl₂ + 2KBr → 2KCl + Br₂
Cl₂ + 2KI → 2KCl + I₂
Br₂ + 2KI → 2KBr + I₂
I₂ + 2KCl → No reaction
It is the attraction between two atoms resulting from a redistribution of their outer electrons. Atoms form chemical bonds in order to make their outer electron shells more stable. Some resist due to some being very big and electronegative
all of the absorbed energy is converted to kinetic energy
Explanation:
When a gas is heated, all of the absorbed energy is converted to kinetic energy. This is because, according to the kinetic theory of gases, the average kinetic energy of gases is directly proportional to temperature.
- As the gas absorbs more heat, the potential energy it carries converted to kinetic energy.
- Potential energy is the energy at rest of a body
- Kinetic energy is the energy due to the motion of the particles of a medium.
- As more heat is added to a body, the kinetic energy continues to increase significantly.
- Eventually, all the absorbed energy is converted to kinetic energy as the gas expands more.
