Answer:What is the volume of 37% HCl?

If however you meant to say 0.025M and assuming you want to prepare 1L solution then the volume of 37% HCl needed should be= (1000 X 0.025X 36.5)/ (37X1.19X10)=2.07 mL diluted to 1 L using DI water. Good day. If you want 0.025 mole HCl solution, you should take a 2.09 ml of your acid.

Explanation:To prepare 5% solution from this acid; simply take 5 ml. of the acid and add it to 95 ml of distilled water.You get a 5%HCl solution. By the way, Hydrogen Chloride is the name designated to the gas evolved from HCl acid

stearic acid and linoleic acid stearic acid and linoleic acid stearic acid has the higher melting point, because it has two more
elena55 [62]

Acid palmitic acid has higher melting point, because it has two more methylene groups.

\text { Myristic acid } \rightarrow \mathrm{CH}_3\left(\mathrm{CH}_2\right)_{12} \mathrm{COOH} \\& \text { Palmitic acid } \rightarrow \mathrm{CH}_3\left(\mathrm{CH}_2\right)_{14} \mathrm{COOH} \\

Acid palmitic acid has higher melting point, because it has two more methylene groups.

Giving it a greater surface area and therefore more intermolecular  van der waals interact than the myristic acid.

stearic arid \mathrm{CH}_3\left(\mathrm{CH}_2\right)_{16} \mathrm{COOH}

linoleic acid \mathrm{C}_{18} \mathrm{H}_{32} \mathrm{O}_2 (two double bond)

Stearic acid has higher Melting point, because it does not have any Carbon-Carbon double bonds, whereas linoleic acid has two cis double bonds which prevent the molecules from packing closely together.

Oleic Acid and Linoleic acid.

\mathrm{C}_{18} \mathrm{H}_{34} \mathrm{O}_2-one double bond (cis)

Acid palmitic acid has higher melting point, because it has two more methylene groups.

Crystals are made using supersaturated solutions of solids in water. These solutions hold more of the solute than they would at
Rudik [331]

Solubility controls the formation of crystals by the mechanism of oversaturation, therefore the correct answer is:

4. The water polo would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.

Crystals are solid structures where there is a fixed spatial arrangement of the molecules, there are many preparation methods, a very practical method and obtaining good crystals is from supersaturated solutions.

Solubility is the mechanism by which a supersaturated solution is formed, for this it is used that the water when heated has more energy and manages to dissolve a greater amount of solute, therefore by decreasing the temperature and consequently reducing the solubility the solution is over saturated.

When introducing some means of disturbance in the solution, the excess of solute is deposited in the form of crystals of excellent quality, this growth method is called hydrothermal synthesis

To achieve controlled supersaturation and crystals the temperature must be controlled precisely, to allow the formation of the crystals.

In conclusion, solubility controls the formation of crystals by the mechanism of over saturation, therefore the correct answer is:

4. The water polo would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.
