The reaction between nitrogen and hydrogen to produce ammonia is described as an equilibrium reaction. what substances are present in the reaction mixture when equilibrium has been obtained?

Explanation:

An equilibrium reaction is defined as the reaction in which the rate of forward reaction is equal to the rate of backward reaction.

For example, an equilibrium reaction between nitrogen, hydrogen and ammonia will be as follows.

Also, in an equilibrium mixture both reactants and products remain in the reaction mixture.

Therefore, we can conclude that in the given reaction mixture when equilibrium has been obtained then substances present in it will be , and .

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
