Covalent Bonds are formed by mutual sharing of electrons
Alexus [3.1K]3 years ago

Answer:

covalent and metallic bonds

Explanation:

Electrons are shared among atoms in both covalent bonds and metallic bonds, but not ionic bonds. Covalent bonds hold atoms together in molecules. Metallic bonds hold together a sample of pure metal or a mixture of metals.

Draw the structure of the major organic product isolated from the reaction of 3-hexyne with hydrogen (1 mol), Lindlar palladium.
ohaa [14]

Answer:

See explanation and image attached

Explanation:

When 1 mole of hydrogen is added to 3-hexyne, the addition occurs on the same face or side of the triple bond to yield cis-2-hexene in the presence of lindlar catalyst which prevents further hydrogenation. This is known as syn addition.

The syn addition is achieved because the hydrogen molecule is first adsorbed on the surface of the palladium metal and is subsequently attached to the same face of the triple bond in 3-hexyne as shown in the image attached to this answer.

PLEASE HELP <br> describe the process of paper chromatography????????????
irinina [24]

Answer:Chromatography technique that uses paper sheets or strips as the adsorbent being the stationary phase through which a solution is made to pass is called paper chromatography. It is an inexpensive method of separating dissolved chemical substances by their different migration rates across the sheets of paper.

You're welcome :)

What is the concentration (M) of a solution with a pH of 9.52 ?
masya89 [10]

Answer:

[H⁺] = 3.02 x 10⁻¹⁰M

Explanation:

Given parameters:

pH of the solution = 9.52

Unknown:

Concentration of the solution

Solution

There is a relationship between the pH and concentration of a solution.

                     pH = -log₁₀[H⁺]

The unknown here is [H⁺],

Now making it the subject of the formula

           [H⁺] = Inverse log₁₀(-pH)

           [H⁺] = Inverse log₁₀(-9.52)

              [H⁺] = 3.02 x 10⁻¹⁰M
