It requires 496.0 kj/mol to break o2 molecules into atoms. calculate the maximum wavelength of light that will still break these molecules apart. enter in nm to 3 significant figures.

Substance x has a fixed volume, and the attraction between its particles is strong .substance y had widely spread out particles and can be compressed what can most likely be concluded about these substances

Why is nh3 classified as a polar molecule

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.
