Determine the percent yield for the reaction in which 15.8 g of NH3 and excess oxygen produce 21.8 g of NO gas and water.

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:

they are both synthetic elements

explanation:

d

b is the correct answer

mark me brainliest and hope this

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
