Answer:
Osmosis.
Explanation:
If there is a selectively permeable membrane which is separating two liquids of different osmolarity or solute concentration then the process by which the solvent will move from one solution to another so as to attain equilibrium is known as osmosis. The existence of a selectively permeable membrane is the basic difference between diffusion and osmosis. Osmosis is characterized by the presence of such membrane which allows the movement of solvent only and restricts the movement of solute. In contrast to this, in diffusion there is no such restriction on the movement of particles from a region of high concentration to a region of low concentration.
In view of above in the given example, the solvent i.e. water will tend to move from pure water side towards the 4% NaCl solution side and the movement will continue until the osmolarity becomes equal on both the sides.
Answer: Neon
Explanation: The second period involves elements with n =2 i.e. the elements have electrons in second shell. The element with filled s and p orbitals will have outer electronic configuration
Thus the element with filled orbital will be a noble gas. It will have total of 10 electrons and the element will be neon with complete outer electronic configuration will be:
Answer:
26.25 mL
Explanation:
This is a dilution problem. First, let us calculate the volume of final solution needed:
The dog weighs 50 pounds and the sedative is administered at 0/7 ml per pound. Hence:
50 x 0.7 = 35 mL
A total volume of 35 mL, 2.5% solution of the sedative will be needed.
But 10% solution is available. There needs to be a dilution with saline water, but what volume of the 10% solution would be diluted?
initial volume = ?
final volume = 35 mL
initial concentration = 10%
final concentration = 2.5%
Using dilution equation:
initial concentration x initial volume = final concentration x final volume
initial volume =
= 2.5 x 35/10 = 8.75 mL
Hence, 8.75 mL of the 10% pre-mixed sedative will be required.
But 35 mL is needed? The 8.75 mL is marked up to 35 mL with saline water.
35 - 8.75 = 26.25 mL
<em>Therefore, 26.25 mL of saline water will be added to 8.75 mL of the 10% pre-mixed sedative to give 2.5%, 35 mL needed for the dog.</em>
Salutations!
A large gently sloping volcano with a fluid eruption is called shield volcano. The fluid is basaltic lava and the slops are gently sliding.
Hope I helped (:
Have a great day!
