Consider the reaction 4NO2(g) + O2(g) -- 2N2O(g) Suppose that, at the a particular moment during the reaction, molecular oxygen is reacting at the rate of 0.024M/s a)At what rate is NO2 begin formed?b)At what rate is NO2 reacting?

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
