A superconductor performs best at very cold temperatures.
Answer:
Evaporation is great for separating a mixture (solution) of a soluble solid and a solvent. The process involves heating the solution until the solvent evaporates (turns into gas) leaving behind the solid residue. ... This method is best for separating a liquid from a solution.
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )
Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. ... Due to the magnets, magnetic particles are being drifted by the movement of the drums. This can create a magnetic concentrate (e.g. an ore concentrate).
Explanation:
That's your answer.
There are several information's already given in the question. Based on those information's the answer can be easily determined.
M = <span>1.11 g CH4
C = </span>4.319 kJ g C⋅°
∆T = 35.65 - 24.85 degree centigrade
= 10.8 degree centigrade.
Then
∆H =−M ⋅ C ⋅∆T
= - 1.11 * 4.319 * 10.8
= - 51.776 kJ/<span>mol
I hope the procedure is clear enough for you to understand.</span>
The energy of the snack in calories per gram is 9983.3 Calories/gram.
<h3>What is the energy of a snack?</h3>
The energy that is contained in a snack is obtained from a calorimeter when the snack is burnt in a calorimeter. The mass of the snack that is burnt is measured in terms of energy output of the calorimeter.
If 1 calorie = 4.18J
x calorie = 41,800 J
x = 41,800 J * 1 calorie/4.18J
x = 9983.3 Calories/gram
