A scientist is combining two gray elements. He thinks he will get a gray compounds. Use what you learned in this lesson to explain why this prediction may not be correct

Explanation:

Depending on the elements that are being combined, a chemical reaction could occur and cause a change of color to take place if the elements reacts to the other one.

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).
