Baking powder solution has an effect on a diluted hydrochloric acid solution by causing the release of carbon dioxide from sodium bicarbonate, a component of baking soda.
One molecule of backing soda + one molecule of hydrochloric acid yields one molecule of sodium chloride (table salt) + one molecule of carbon dioxide + one molecule of water.
HCl + NaHCO₃=NaCl+H₂CO₃
However, carbonic acid is quite unstable:
H₂CO₃ = CO₂ + H₂O
HCl + NaHCO₃ = NaCl + H₂O (Water) + CO₂.
Effervescence, which is a fast bubble formation, is how liquid releases CO2.

Okay, let's look at the oxidation number of each substance.
-Br2 has an oxidation number of 0 because it is in a stable form.
- I- has a -1 charge and thus has an oxidation number of -1.
- 2Br- has a -1 charge also
- I2 has an oxidation number of 0 as well.
Bromine goes from 0 to -1 and Iodine goes from -1 to 0.
Therefore, Bromine is having an electron added whilst Iodine is having an electron removed.
Oxidation is Loss of electrons so Iodine is being oxidised, Reduction is Gain of electrons so Bromine is being reduced.
Answer:
What leads to the formation of a wind chill factor? A change in the air temperature creates air pressure differences in the atmosphere
