For the reaction N2(g) + 3H2(g) 2NH3(g), what will happen if hydrogen gas was removed from the reaction mixture? There will be a

shift toward the products. There will not be a shift in equilibrium. There will be a shift toward the reactants. The value for Keq will change.

This uses something called <span>Le Chatelier's principle. It states essentially that any stress put upon a system will be corrected.

In more simple terms, it means that in an equilibrium, such as the equation N2(g) + 3H2(g) <=> 2NH3(g), removing a reactant will cause the system to create more of said reactant to compensate for its loss, or adding excess reactant will cause the system to remove some of the added reactant. For future reference, the same principle applies to products in an equilibrium as well. 

In this case, hydrogen gas is a reactant, and hydrogen is being removed. According to </span><span>Le Chatelier's principle, the system will shift to create more hydrogen gas. In essence, it will shift in the direction of the hydrogen gas, so there will be a shift toward the reactants.

To clear something up, Keq will not change, as it is a constant value with constant conditions (such as temperature, pressure, etc.).</span>

True or False: Mutually beneficial relationships, predator-prey relationships, and competition can happen in different environme
Masja [62]

Answer:

Yes :)

Explanation:

Mutual relationships can include birds cleaning out aligators' teeth, which helps with their hygiene, and gives the bird a meal!

Predator-prey would be a cheetah-antelope.

Competition could be an invasive species :)

Hydrogen is a gas at a room temperature, but it is found with the alkali metals in group 1 (1A) on the periodic table. Which is
bearhunter [10]
Hydrogen is grouped with the alkali metals because they are grouped based on their properties and behavior, and like the other elements in Group 1 (1A), it only has one valence.

HNO3 Express your answers as ions separated by a comma.
erastovalidia [21]
In this item, it is assumed that we are to express the given compound in their ionic form. To be able to determine as to what ions this compound will dissociate into, we have the chemical reaction.

                     HNO3 --> H⁺  + NO₃⁻

Hence, the ions are H⁺, NO₃⁻.
