The specific heat of fat is 0.45 cal/(g C) and the density of fat is 0.94g/cm^3 . How much energy (in calories) is needed to heat 10cm^3 of fat from room temperature (25 C) to its melting point (35 C).
What is the energy of a violet photon with wavelength 4.0 x 10^-7 m?
Compare the orbital electronic configuration for K and Rb (s block), Hf and Zr (d block), F and Cl (p block). For each element, which ionic configuration should be the most stable?
Many drugs are high-molecular-weight amines that are weak bases. Such amines are not soluble in water, which limits the ways they can be administered and means that they are not soluble in body fluids such as blood plasma and cerebrospinal fluid
