<span>The two techniques for separating an insoluble solid from a liquid are filtration and centrifuging. Filtration relies on the fact that the solid particles are smaller than the filter paper pores which allow the tiny molecules of liquid to pass through. With solids which dissolve in a liquid solvent, evaporation is commonly used to recover the solid and distillation is used to recover the solvent.</span>
Answer:
There is no percent left for other foods
Explanation:
The total energy consumed was:
E = 2x1.2x10⁶ + 3x6.7x10⁵ =
E = 4.41x10⁶ J
Knowing that 1 cal = 4.184 J
1 cal --------- 4.184 J
y ---------------- 4.41x10⁶ J
By a simple direct three rule:
4.184y = 4.41x10⁶
y = 1.05x10⁶ cal
Which is higher than the 2000 calorie daily food intake, so there is no percent left for other foods.
Answer : The correct option is (B).
Explanation :
Body-centered cubic structure (bcc) :
Crystal structure : The manner in which the atoms or ions are spatially arranged.
In bcc arrangement, the atoms are present at eight corners of the cube and at the center of the cube. And the coordination number is 8.
Each unit cell has atoms at the corner and 1 full atom at the center of the cube.
Therefore, the each unit cell has atoms.
Image of bcc structure is shown below.
