What are the components needed in order for an experiment to be valid? identify these components in the following experiment: a scientist is testing a new plant food to see if it causes plants to grow faster. the scientist tests two plants with the new plant food, and two plants he grows without plant food.

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).
