Answer:
it should be momentum if im not mistaken

Answer: Adding a reactant will shift the reaction towards the products.
Adding a product will shift the reaction towards the reactants.
Removing a reactant will shift the reaction towards the reactants.
Removing a product will shift the reaction towards the products.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
Adding a reactant will increase the concentration of reactants and hence the reaction will try to undo the increase by shifting the reaction towards the products.
Adding a product will increase the concentration of products and hence the reaction will try to undo the increase by shifting the reaction towards the reactants.
Removing a reactant will decrease the concentration of reactants and hence the reaction will try to undo the decrease by shifting the reaction towards the reactants.
Removing a product will decrease the concentration of products and hence the reaction will try to undo the decrease by shifting the reaction towards the products.
