Consider the reactionn2o4(g)→2no2(g) where n2o4 is colorless and no2 is brown. at a temperature of 5∘c, the reaction is colorless at equilibrium. this indicates that the equilibrium constant for this reaction at this temperature is consider the reactionwhere is colorless and is brown. at a temperature of 5, the reaction is colorless at equilibrium. this indicates that the equilibrium constant for this reaction at this temperature . negative. b. large. c. small (less than 1).d. zero, because equilibrium can only be obtained at room temperature.

The reaction q+r2=r2q is found to be first order in r2 and

What is the atomic number of an atom that has 6 protons

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
