How would you expect the solubility of silver fluoride (AgF) to compare to the halides measured in lab (AgBr, AgCl, AgI)? Explain your reasoning using atomic and ionic properties.
a 0.0450 m solution of para-aminobenzoic acid had an absorbance of 0.844 at 267 nm in a 1.00 cm cuvet and an absorbance
the experimental density of nickel under normal conditions of temperature and pressure is 8.908 cm^-3. Predict its crystal structure, and use the experimental density to obtain an experimentally-corrected atomic radius.
