Equal amounts of N2 and O2 are added, under certain conditions, to a closed container. Which changes occur in the reverse reacti
geniusboy [140]
1) The forward reaction is N2 (g) + O2 (g)  → 2NO

(that reaction requires special contitions because at normal pressures and temperatures N2 and O2 do not react to form another compound.

2) The equiblibrium equation is

  N2 (g) + O2 (g)  ⇄ 2NO

3) Then, the reverse reaction is

2NO → N2(g) + O2(g)

Answer: 2NO → N2(g) + O2(g)

How are the three phrases of agriculture (shifting, labor-intensive, mechanized monoculture) different in terms of description,
natka813 [3]

Answer:

Explanation:

Shifting, labor intensive and monoculture are different in terms of description,restrictions and problem.

Shifting is an agriculture method in which an area if land is cultivated for a while and abandoned for the soil to regain and preserve it's fertility. It is done to restore soul fertility.

It has restrictions because it is done in places where there is large areas of land, if there is not large area of land, it will be done.

It can lead to defforestation because trees are cut fine for land cultivation and after a while the land is abandoned and trees are cut down some where else too.

Labor intensive refers to agricultural industry requiring or needing large amount of labor to produce agricultural products. Labor intensive is restricted to areas where there is low or no people who can engage in agricultural services.

Labor intensive require high skilled people which might not be available.

Monoculture is a farming system where by a single crop is cultivated in an area of land.

The problem of monoculture is that it displaces species and nutrients occuring naturally in an ecosystem.

Monoculture is restricted in areas where diversity of crops are needed.
