Answer:
No-till conservation tillage
Explanation:
No till conservation involves the soil not being touched which gives rise to a large amount of organic matter being left on the surface.
The Advantage of this method is that it helps to prevent erosion such as that of wind and water due to the little or no exposure of the soil surface and helps to provide nutrients to the plants through the organic matter present.
The Disadvantage of this method is its heavy reliance of chemicals such as herbicides in killing the weeds in order to prevent competition for vital compounds with the main plants.
Answer:
Synthesis
Explanation:
That's the answer to that question
Answer:
6
Explanation:
Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
For the given chemical reaction:
The half cell reactions for the above reaction follows:
Oxidation half reaction:
Reduction half reaction:
Magnesium is loosing 2 electrons to form the magnesium cation. Thus, it is getting oxidized. Aluminum anion is gaining 3 electrons to form Aluminum. Thus, it is getting reduced.
Thus, balancing the half-reactions as:-
Oxidation half reaction:
Reduction half reaction:
Thus, total number of electrons transferred = 6
