Would you date me?? Nevermind I know it is going to be a no I am ugly. Anyways I am 13

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

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.

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?
