Draw all Newman projections of 1-chloro-3-methylbutane as they rotate about the point of view indicated in the following drawing. Label them (anti, gauche, edlipsada) and place them in descending order of energy.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

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.

Measurements that have similar values are: a. usually accurate b. sometimes accurate c. always accurate d. never accurate
