Answer:
d. is the hydrostatic pressure produced on the surface of a semi-permeable membrane by osmosis.
Explanation:
Osmosis -
It is the flow of the molecules of solvent from a region of higher concentration towards the region of lower concentration via a semipermeable membrane , is known as osmosis.
Osmotic pressure -
It refers to the minimum amount of pressure , which is required to be applied to the solution in order to avoid the flow of pure solvent via the semipermeable membrane , is referred to as osmotic pressure.
Or in simple terms ,
Osmotic pressure is the pressure applied to resists the process of osmosis.
Hence ,
From the given options in the question,
The correct option regarding osmotic pressure is d.
Answer is: Not all mixtures have solutes and solvents.
Solution is homogeneous mixture composed of two or more substances.
In aqueous solution, solvent is water and solute (for example salt) is a substance dissolved in water.
Homogeneous solution of salt and water can be separated with heating (evaporating the water).
Hydrocarbons which contain only single bonds are called alkanes. <span>This gives them a general </span><span>formula CnH2n</span>+<span>2. Given we are given eight carbon atoms then it should be that it would have 2(8)+2 = 18 hydrogen atoms. Therefore, the statement is true.</span>
The volume of the radiator solution formed with the 197 mL of antifreeze is 788 mL.
<h3>What is a percentage?</h3>
A percentage is given as the respective ratio of the quantity present with respect to others.
The solution of 25% v/v can be depicting the presence of a 25% volume of antifreeze in the radiator solution.
The volume of the radiator solution has 197 mL of antifreeze. The total volume of the solution suppose is x.
25% of x = 197 mL
25/100 * x = 197
x = 788 mL
The volume of the radiator solution formed with 25% v/v antifreeze is 788 mL.
