What will occur when the following chemical reaction reaches dynamic equilibrium?
3H2 + N2 = 2NH3
A. The concentrations of all reactants and products will be the same.
B. No further chemical reactions will occur in either direction.
C. The concentrations will continue to change gradually over time.
D. The product will form at the same rate at which it decomposes.

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
