Initially, only A and B are present, each at 2.00 M . What is the final concentration of A once equilibrium is reached? What is the final concentration of D at equilibrium if the initial concentrations are [A] = 1.00M and [B] = 2.00 M?
The reversible chemical reaction A + B ↔ C + D has the following equilibrium constant: Kc = [C][D]/[A][B] = 4.7.

Match each object to its description: a. coma of a comet b. comet tail c. oort cloud haze surrounding a nucleus created by solar wind. hypothetical sphere around the solar system

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.)
