I think 02 83.92 pretty sure
Answer:
Oxidation half-reaction : Na(s) → Na⁺ + 1 e-
Reduction half-reaction: Cl₂ + 2 e- → 2 Cl⁻
Explanation:
Oxidation half-reaction: solid sodium (Na(s)) has an oxidation number of 0. It loses 1 electron and forms the cation Na⁺. So, the half-reaction is the following:
Na(s) → Na⁺ + 1 e-
Reduction half-reaction: chlorine gas (Cl₂) has an oxidation number of 0. Each atom of Cl gains 1 electron to form two Cl⁻ ions, according to the following half-reaction:
Cl₂ + 2 e- → 2 Cl⁻
The total oxidation-reduction reaction is obtained by adding the oxidation half-reaction multiplied by 2 (to balance the electrons) and the reduction half-reaction, as follows:
2 x (Na(s) → Na⁺ + 1 e-)
Cl₂ + 2 e- → 2 Cl⁻
--------------------------------
2Na(s) + Cl₂ → 2NaCl
Answer:
The charge on iodine is 2-
Answer:
See explanation
Explanation:
Freezing point and melting point increases slightly at higher altitude
The boiling point decreases at higher altitudes.
Air pressure decreases with altitude As a result of this, atmospheric pressure decreases and water must now boil at a lower temperature. In order to compensate for this lower boiling point of water, food must take a longer time to cook. The lowering of air pressure actually means that the air becomes thinner at higher altitudes.
Pressure cookers cook food at high pressure thereby reducing the cooking time significantly. This helps to retain 50% of the nutrients in the food, lower the kitchen temperature and lower the energy cost required to cook food.
