Which statement best summarizes the importance of ernest rutherford’s gold foil experiment?
it proved that all of john dalton’s postulates were true.
it verified j. j. thomson’s work on the atomic structure.
it showed that an electron circles a nucleus in a fixed-energy orbit.
it showed that a nucleus occupies a small part of the whole atom.

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).

so what is the problem with your lab report and whats the subject of the lab report? i will you
