Amount of carbon dioxide present will decrease C.) the amount of carbon dioxide will be unchanged D.) the equilibrium constant will have to decrease to compensate E.) More info is needed - Answer -A.) Amount of carbon dioxide present will increase 2NaHCO3 (s) <---> Na2CO3(s) + H20(g) + Co2 (g) what happens to the system when sodium carbonate is added? A.) the concentration of carbon dioxide will increase B.) the concentration of carbon dioxide will decrease C.) the concentration of carbon dioxide will be unchanged D.) the amounts of all the products will be greater once equilibrium is reattained E.) need more info - Answer -C.) the concentration of carbon dioxide will be unchanged 3A(g) + 2B(g) --> 2C(g) at 100 degrees celcius, a mixture of these gases at equilibrium showed that [A]=.855 M [B]=1.23 [c]=1.75 M. What is the value of Kc for this reaction? - Answer -3.24 write the Qc for the following chemical reaction Fe3+ (aq) + 3OH- (aq) <---> Fe(OH)3(s) - Answer -1/[fe3+][OH-]^3 The reaction system POcl3 (g)<---> Pocl (g) + cl2 (g) Need assistance on Online classes, Exams & Assignments?
