Ethanol melts at -114°C and boils at 78°C. The enthalpy of fusion of methanol is 5.02 kJ/mol, and is enthalpy of vaporization is 38.56 kJ/mol. The specific heat of solid and liquid ethanol are 0.97 and 2,3 J/g-K respectively. A) How much heat is required to convert 26.0 g of ethanol at 25°C to the vapor phase at 78°C. B) How much heat is required to convert the same amount of ethanol at -150°C to the vapor phase at 78°C.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
