Answer: Water and acetone
Explanation: you will find that the water and the soil are polar opposite, while the principal component of the water are Hydrogen and Oxygen, in the acetone you will find a change of carbon, the components from each molecule confer to each one specific physical properties for example the boiling point, and the distillation is a physical separation based on the boiling point.
then you can find the boiling point of the water in 100 °C, and the boiling point of the acetone is 56 °C, this give as a difference of 44 °C,
then while the acetone is boiling the water is liquid state, and this give us the opportunity to the separate the acetone in gas state by condensation after the boiling.
Answer:
665 kJ
Explanation:
We assume that carbohydrates and protein each have 4 kilocalories per gram, and that fat has 9 kilocalories per gram. Then the number of kilocalories in the peanut butter is ...
4(6 +9) +9(11) = 159 . . . . kilocalories
Each kilocalorie translates to 4.184 kilojoules, so the total is ...
(159 kCal)(4.184 kJ/kCal) = 665.256 kJ
2 Tbsp of crunchy peanut butter contains about 665 kJ of energy.
