Whats the options? I need to see some options before I answer please if there are any..
Answer:
d. it’s reduced
Explanation:
An oxidation-reduction reaction, commonly known as REDOX reaction is a type of reaction that involves the transfer of electrons from one atom to another characterized by a change in oxidation number. The atom that loses electrons is said to be OXIDIZED while the atom that gains electrons is said to be REDUCED.
Therefore, in this question describing the half reaction of an oxidation reduction to show that iron atom (Fe) gains electrons. This indicates that the IRON atom is being REDUCED because it's oxidation number will reduce after gaining electrons.
Answer:
3.55 x 10^23 molecules F2
Explanation:
molecules = moles x avogadro number
1 mole of gas occupies 22.4 L
moles of F2 = 13.2/22.4= 0.589 moles
moles F2 = 0.589 x 6.022 x 10^23 = 3.55 x 10^23 molecules F2
Due to erosion, the soil is taken away from one place to another.This decreases the fertility of the land,.. it also is a cause for floods. Due to erosion, the vegetation is destroyed and nothing can be cultivated for a higher yield in the rough sandy land . Due to weathering of rocks, there is an advantage. The advantage is that the weathering of volcanic rocks give rise to Black Soil by which special crops like cotton,tobacco and sugarcane can be cultivated. Due to weathering, a hilly range may turn into a plain land after thousands of years.
