Agas stream containing n-hexane in nitrogen with a relative saturation of 90% is fed to a condenser at 75°c and 3.0 atm absolute. the product gas emerges at 0°c and 3.0 atm at a rate of 746.7m3/h. calculate the percentage condensation of hexane (moles condensed/mole fed) and the rate (kw) at which heat must be transferred from the condenser

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
