A chemical reaction occurred in a closed container. Which is true of the equation of the reaction as shown below? N2 + 3H2 -> 2NH3 A. The mass and molecules of the reactants equal the mass and molecules of the products.

B. The volume and mass of the reactants equal the volume and mass of the products.

C. The molecules and atoms of the reactants equal the molecules and atoms of the products.

D. The atoms and mass of the reactants equal the atoms and mass of the products.

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:

lol for the pointsss

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
