A2-m-diameter, thin-walled stainless steel spherical tank is filled with chemicals undergoing a reaction. the reaction releases heat through the tank, where the tank outer surface temperature is 50°c and is exposed to air at 20°c. the stainless steel surface of the tank has an emissivity of 0.35. determine the rate of heat release from the chemical reaction inside the tank. is the given emissivity value reasonable for a stainless steel surface? what is the contribution of natural convection to the overall rate of heat loss at the tank surface?

Rank substituents in order of their priority when assigning the e or z label to an alkene. i, ch2i , h, ch2ch2cl, f

The bohr model of the atom explained why emission spectra are discrete. it could also be used to explain the photoelectric effect. which is a correct explanation of the photoelectric effect according to the model?

What is the difference between covalent bonds and ionic bonds? covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the electrical attraction between charged atoms. covalent bonds involve the transfer of electrons between charged atoms; ionic bonds involve the sharing of electrons between atoms. covalent bonds involve the sharing of pairs of electrons between atoms; ionic bonds involve the sharing of single electrons between atoms. covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the sharing of protons between charged atoms.
