Amixture of mole fraction 0.500 ethanol and 0.500 water at 25°c is fed continuously to a vessel at a rate of 500 kg/hr. the liquid is partially vaporized to a vapor with mole composition of 0.832 ethanol, with the remaining liquid 0.127 ethanol. both the liquid and vapor exiting streams have a temperature of 71 °c. (a) draw pfd for the process. (b) write the appropriate energy balance, with cancelled terms. (c) how much heat must be transferred to the mixture?

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
