How you would go about separating a mixture of salt and sand. Knowing that salt will dissolve in water. Device a method to separ
DanielleElmas [232]

Separating a mixture of salt and sand will involve two main techniques such as filtration and evaporation.

<h3>What is Filtration?</h3>

This is a technique which is used to separate a fluid from a solid matter such as sand etc.

Since salt dissolves in the water, the fluid is collected using the filter paper placed inside the funnel. After which it enters the Erlenmeyer flask and is heated to allow for evaporation of water and collection of the salt.

Select the single best answer. When 2-heptyne was treated with aqueous sulfuric acid containing mercury(II) sulfate, two product
Mamont248 [21]

Answer:

heptan-3-one and heptan-2-one

Explanation:

In this case, we must remember what the products of this reaction are. An alkyne in the presence of HgSO4 and H2SO4 will produce a ketone. But, in the triple bond, we have two carbons, therefore the carbonyl group can be placed on any of the carbons of the triple bond.

In figure 1 we have the general reaction. At C = O it can be added to the carbon on the left (red carbon) or the carbon on the right (blue carbon).

Following this logic, for 2-heptyne the carbonyl group can be added to carbon 2 producing <u>heptan-2-one</u>. Similarly, the carbonyl group can be added to carbon 3 producing <u>heptan-3-one</u>. (See figure 2)
