The volume of copper : 3.24 ml

<h3>Further explanation </h3>

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of mass

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

\large{\boxed {\bold {\rho~=~ \frac {m} {V}}}}

ρ = density , g/cm³ or kg/m³

m = mass , g or kg

v = volume , cm³  or m³

A common example is the water density of 1 gr / cm³

The density of copper : 8.96 gr/ml

mass of copper : 29 g

then the volume :

\tt V=\dfrac{m}{\rho}\\\\V=\dfrac{29~g}{8.96~g/ml}\\\\V=\boxed{\bold{3.24~ml~or~3.24~cm^3}}

The answer is "filtration"
Filtration is used to separate solids from liquids or liquids from gases by adding a medium through which only the liquid can pass. The fluid that passes through is called filtrate.

I hope this helps.

Complete the mechanism for the electrophilic addition when the alkene is treated with water in acid.
s344n2d4d5 [400]

Answer:

CH₃CH == CH₂  +  H₂O → H⁺ →  CH₃CH(OH)CH₃  +  H⁺

The reaction of propene and water in acidic medium produces isopropyl alcohol.

Explanation:

Let's propose the following reaction:

Propene + H₂O in H⁺ medium  →  Alcohol

CH₃CH == CH₂  +  H⁺ →  CH₃C⁺CH₂

Electrons from the double bond attack the proton. So the double bond is broken and you form a carbocation.

Carbocation will be attacked by the electrons from the oxygen on the molecule of water.

CH₃C⁺CH₂  + H₂O: :  →  CH₃ _CH _ CH₃  

                                                   |

                                                ⁺OHH

It is called electrophilic addition cause the proton which is the electrophile is added to the sp₂ carbon in the alkene (where many H are bonded),  and the nucleophile, water is added to the other sp₂ carbon.

This last attack is so fast that the carbocation is combined with any nucleophile which it collides first. In the hydration reaction, there are two nucleophiles: water and the anion from the acid (let's think Cl⁻, cause our medium can be HCl).    The product of this collision is a protonated alcohol. Since we know that protonated alcohols are very strong acids, this protonated alcohol loses a proton, and the end product of the addition reaction is an alcohol.

In the first step, a proton adds to the alkene, but is returned to the reaction mixture during the final step, when the alcohol is deprotonated.

 CH₃ _CH _ CH₃   →   CH₃ _CH _ CH₃   + H⁺

             |                                 |

          ⁺OHH                          OH

Which has the larger radius, F or F− ?
vlabodo [156]

Answer is B-  F has a smaller radius than F− because an additional electron causes greater repulsion in F− is the correct choice and the nuclear charge the radius of the anion increases.
