Write the balance equation that would give the following equilibrium. K= [NO2]2/ [NO]2 [O2]

The creation of shells by mollusk species is a fascinating process. By utilizing the Ca2+ in their food and aqueous environment, as well as some complex equilibrium processes, a hard calcium carbonate shell can be produced. One important equilibrium reaction in this complex process is HCO3(aq)H+(aq)+CO32(aq)K=5.61011 If 0.16 mole of HCO3 is placed into 1.00 L of solution, what will be the equilibrium concentration of CO32?

Calculate the value of the equilibrium constant for the reaction N2(g)+2O2(g)2NO2(g) if the concentrations of the species at equilibrium are [N2] = 0.0013, [O2] = 0.0024, and [NO2] = 0.00065.

According to the Resource Conservation and Recovery Act (RCRA), waste material is classified as toxic and must be handled as hazardous if the lead concentration exceeds 5 mg/L. By adding chloride ion, the lead ion will precipitate as PbCl2, which can be separated from the liquid portion. Once the lead has been removed, the rest of the waste can be sent to a conventional waste treatment facility. How many grams of sodium chloride must be added to 500 L of a waste solution to reduce the concentration of the Pb2+ ion from 10 to 5 mg/L?

Write the balanced chemical reaction for this equilibrium expression: K= [H2O]P[O2] [H2O2]?

B. Write the balance equation that would give the following equilibrium. [NO2]2 Kc = [NO]2 [O2]

Calculate the equilibrium constant (Keq) for the following reaction. At equilibrium the [N2O4 ] = 0.0435 M [ NO2 ] = 0.0125 M   N2O4 (g) ⇆ 2 NO2 (g)

Which is the correct equilibrium expression for the following reaction? Assume <--> is the equilibrium arrow, even though it doesn't really look like it!   2 PbO (s)  +  O2 (aq)  <––>   PbO2 (s)

The equilibrium between carbon dioxide gas and carbonic acid is very important in biology and environmental science.                      CO2 (aq) + H2O (l) <--> H2CO3 (aq)            What would be the equilibrium constant expression (Kc) for this reaction?
