Which electrons in an atom will have the same amount of energy?
a
electrons in the same atom will have the same amount of energy.

b
electrons with the same spin will have the same amount of energy.

c
electrons in the same orbitals will have the same amount of energy.

d
electrons with the same charge will have the same amount of energy.

C

Explanation:

Electrons need to have a certain amount of energy to move between orbitals, so electrons in the same orbitals will have the same amount of energy because they had to move to that orbital.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
