Answer:
At a 500 mL volumetric ballon, it will be added a little of distilled water, then 1 mL of the pure detergent, and then it will be added water until the meniscus. The solution will be agitated by inverting the flask until it's homogeneous.
Explanation:
In its pure state, the detergent has a 100% concentration. Thus, knowing that the product of the concentration by volume must be constant, we can do:
C1V1 = C2V2
Where C is the concentration, V is the volume, 1 is the pure detergent, and 2 the solution. So, let's find the volume of pure detergent needed to prepare 500 mL of the solution:
100*V1 = 0.2*500
100V1 = 100
V1 = 1 mL
Thus, at a 500 mL volumetric ballon, it will be added a little of distilled water, then 1 mL of the pure detergent, and then it will be added water until the meniscus. The solution will be agitated by inverting the flask until it's homogeneous.
Hello, Lindaparker, a spit could form from a rocky headland where prevailing winds would
blow at an angle to the rocky headland, gradually depositing sand and
shingle at that place. A spit is a permanent land form resulting
from marine deposition and wind deposition. It is usually a long and
narrow accumulation of sand or shingle with one joined to the land and
the other end projecting at a narrow angle out into the sea. Salt marshes sometimes form on the sheltered side of a spit.
Answer:
0.4941, 0.5059
Explanation:
= Partial pressure of nitrogen = 417 mm Hg
= Partial pressure of xenon = 427 mm Hg
Total pressure in the system is given by
Mole fraction is given by
For xenon
or
So, mole fraction of nitrogen is 0.4941 and xenon is 0.5059.
