Calculate the ph of 100 ml of a buffer solution that is 0.063 M in phenol C6H5OH (Ka =1.3x 10^-10) and 0.13 M in NaC6H5 after (a) 0 ml and (b) 10 ml of 0.75M HCL is added

A100-watt light bulb radiates energy at a rate of 100 j/s. (the watt, a unit of power or energy over time, is defined as 1 j/s.) if all of the light emitted has a wavelength of 525 nm , how many photons are emitted per second?

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

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