12. When a 120 g sample of aluminum is placed in 250 g of water the temperature increases from 25°C to 115°C. Find the energy per gram of aluminum. A. Find the percent efficiency per gram if the theoretical yield was 8500 J/g.

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).

explanation:

the millers tale is the answer.

you gotta add the following molecules so we can give u an answer
