Answer:
The Cape Horn was one of the most important routes for maritime trade, leading to sailing vessels.
the difficulty of all this is that it presents great iceberg and climatic factors that do not help the boats. nowadays other commercial routes were created that made this channel only be transited by larger ships, or oil tankers.
Explanation:
Sailing in its waters is still considered one of the greatest nautical challenges, so there are various sporting and tourist events that use this route, some as part of the circumnavigation of the globe, among which are important yacht regattas, such as the Vendée Globe.
is used to test for the presence of starch. Starch turns into an intense "blue-black" colour upon addition of aqueous solutions of the triiodide anion, due to the formation of an intermolecular charge-transfer complex. In the absence of starch, the brown color of the aqueous solution remains.
Answer:
It forms a solution.
Explanation:
A pure substance is when only one type of atom or molecule is present. In this case the substance contains two different molecules; sugar and water, assuming sugar is all one type (e.g. glucose) and there are no contaminants in the water or sugar before combining the two.
Dissolving the sugar in the water makes a homogeneous mixture and once dissolved a solution is made by the combination of a solute (sugar) and solvent (water).

The organ known as the cemetery of the red blood cells is called “spleen”
An organic reaction between a substituted alkene and a conjugated diene to form a substituted cyclohexene derivative is said to be Diels-Alder reaction (specifically, [4+2 cycloaddition). The formation of new 
-bonds is the driving force of this reaction, which is energetically more stable than the 
-bonds.
The reaction that takes place due to the heating of dimethyl maleate in presence of 3-sulfolene is as shown in the image.
On heating 3-sulfolene the compound breaks down to give sulfur dioxide gas and butadiene. This diene then reacts with dimethyl maleate which acts as a dienophiles and then these two diene and dienophiles will undergo a Diels-Alder reaction to form a new 6-membered cyclohexene ring.
Thus, the product formed due to the heating of dimethyl maleate in presence of 3-sulfolene is dimethyl cyclohex-4-ene-1,2-dicarboxylate.
