Answer:

See explanation.

Explanation:

Hello,

In the attached picture you will find the required mechanism.

1. The first step is the dissociation of chlorine by the effect of hear or light.

2. Then, the chlorine is able to "steal" a hydrogen from the 2-methylbutane based on Markovnikov's rules so a free radical is formed as well as hydrogen chloride.

3. Then, the previously formed free radical is attacked by the remaining chlorine to yield the 3-chloro-2-methylbutane.

At the end the overall reaction is shown.

Regards.

Answer:

See explanation below

Explanation:

First, we need to understand that the monochlorination of an alkane like this one, involves substitution of one of the atoms of hydrogen of the molecule for an atom of chlorine.

This reaction takes place when the alkane reacts with Cl₂ in presence of light or heat.

When this happens, the first step involves the breaking of the double bond of the chlorine to form the ion Cl⁻.

The next step involves the substraction of the hydrogen of the molecule by the Chlorine. This will leave the alkane with a lone pair available for reaction.

The third step, the alkane with the lone pair of electron substract a chlorine for the beggining and form the mono chlorinated product.

The final step involves forming the remaining products with the remaining reagents there.

In the picture attached you have the mechanism and product for this reaction:

Which models of the atom in task 1 are not supported by the results of the hydrogen gas experiment? For each of these models, ex

kramer

Answer:

Thomson placed two magnets on either side of the tube, and observed that this magnetic field also deflected the cathode ray. The results of these experiments helped Thomson determine the mass-to-charge ratio of the cathode ray particles, which led to a fascinating discovery, minus the mass of each particle was much, much smaller than that of any known atom. Thomson repeated his experiments using different metals as electrode materials, and found that the properties of the cathode ray remained constant no matter what cathode material they originated from. From this evidence, Thomson made the following conclusions:

The cathode ray is composed of negatively-charged particles.

The particles must exist as part of the atom, since the mass of each particle is only ~1/2000 the mass of a hydrogen atom.

These subatomic particles can be found within atoms of all elements.

While controversial at first, Thomson's discoveries were gradually accepted by scientists. Eventually, his cathode ray particles were given a more familiar name: electrons. The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms were indivisible. In order to account for the existence of the electrons, an entirely new atomic model was needed.

How do you calculate net force?

bogdanovich [222]

How to find net force

The net force is the vector sum of all forces act upon an object.

The formula to calculate net force is Fnet = ma
where the net force is equal to the mass of an object (in Kg) multiplied by the acceleration of the object (in meters per second squared)

You may also calculate the net force acting upon an object with Fnet = Fa + Ff
where the net force is equal to the sum of the applied force and the force of friction.
