Daniel has a sample of pure copper. its mass is 89.6 grams (g), and its volume is 10 cubic centimeters (cm3). what’s the density of the sample? a. 0.11 g/cm3 b. 8.96 g/cm3 c. 11.1 g/cm3 d. 896 g/cm3

Density = mass /volume = 89.6/10 = 8.96gm/cm^3.

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).
