Which molecule undergoes e1 fastest in concentrated h2so4

Predict the products butane (c4h10) + oxygen —>

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.

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
