What has research determined about the orbit of an electron around a nucleus? Electrons orbit in exact energy levels. Electrons orbit the nucleus in circular motions exactly as shown on the classic Bohr model. Electrons orbit and remain within specific energy rings. Each sub-level electron type has a unique path where it will likely be found.

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).

explanation:

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
