Answer : The electrons are gained and the oxidation number of chromium decreases.
Explanation :
As we know that a redox reaction is a reaction in which the oxidation and reduction takes place simultaneously.
Oxidation reaction : The reaction where a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : The reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
The balanced half reaction will be :
In this reaction, the oxidation number of 'Cr' changes from (+3) to (+2) that means 'Cr' gains 1 electron and it shows reduction or the oxidation number decreases.
Hence, the electrons are gained and the oxidation number of chromium decreases.
Answer:
Humdity would decrease hence temprature would do the same, hence tundra are called deserts at times.
Explanation:
Answer:
it is called the prevailing westerlies
Explanation:
Answer:
264g
Explanation:
C + O2 -> CO2
_g + _g -> 396g
396÷3=132
C (132g) + O2 (264g) -> CO2 (396g)
Soil bacteria convert atmospheric nitrogen into ammonia, nitrites, and then nitrates. This nitrates are then absorbed by producers.
<h3>What is nitrogen fixation?</h3>
Nitrogen fixation is a process that converts atmospheric nitrogen (N2), into available forms such as ammonia, nitrates, or nitrites to plants so that the plant can absorb it and make amino acids so we can conclude that Soil bacteria convert atmospheric nitrogen into ammonia, nitrites, and then nitrates. This nitrates are then absorbed by producers.
