Increasing the temperature will cause the particles to move more often with more energy. They will therefore collide faster with greater energy
Answer:
Explanation:
<u>1. Oxidation half-reaction (given)</u>
- 2S₂O₃²⁻ (aq) → S₄O₆²⁻ + 2e⁻
<u>2. Reduction half-reaction:</u>
Reduction is the gain of electrons with the consequent reduction in the number of oxidation.
The starting reactant is iodine which is diatomic; thus, it is I₂.
Each iodine atom gains one electron; thus, in total 2 electrons are gained and each I atom in solution will become an I⁻ anion.
Half-reaction:
- I₂ (aq) + 2e⁻ → 2I⁻(aq) ↔ answer
The overall reaction of thiosulfate anion with iodine is obtained when you add the two half-reactions:
- 2S₂O₃²⁻ (aq) → S₄O₆²⁻ + 2e⁻
===============================
(the electrons are canceled)
- 2S₂O₃²⁻ (aq) + I₂ (aq) → S₄O₆²⁻ + 2I⁻(aq)
They are both in the same family/group.
preferAnswer:
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. Atoms will react to get in the most stable state possible

The same argument can be made for the process of freezing: energy is put into a liquid during melting, so freezing the liquid into a solid again returns that energy to the surroundings. Like phase changes, chemical reactions can occur with the application or release of heat.
