Calculate the surface area of the egg (in μm2). the formula for calculating the surface area (sa) of a sphere is given below. sa = 4πr2 use 3.14 as the value for π . d=100

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.
