Answer:

Describe the scientific method/process and list its steps:

The scientific method consists of six steps:

1. Define purpose

2. Construct hypothesis

3. Test the hypothesis and collect data

4. Analyze data

5. Draw conclusion

6. Communicate results

But what is it?

The scientific method is a process with the help of which scientists try to investigate, verify, or construct an accurate and reliable version of any natural phenomena.

Define speed and velocity:

Speed is the quantitative measure of how quickly something is moving. Velocity defines the direction of the movement of the body or the object. Speed is primarily a scalar quantity. Velocity is essentially a vector quantity. It is the rate of change of distance.

List the three Laws of Isaac Newton and provide an example for each law.

1 -  An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.

(example: A coin put on top of a paper on the table will stay in place when the paper is pulled.)

2 - That force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration, i.e. F = m*a.

(example: A truck which carries less mass will have a bigger acceleration that a truck which carries more mass)

3 - States that for every action there is an equal and opposite reaction.

(example: Our hand feels pain when we hit the table because the table gives force as a reaction to our hand)

List the two types of waves.

1. Mechanical Wave -->  A mechanical wave is a wave that is an oscillation of matter and is responsible for the transfer of energy through a medium.

2. Electromagnetic Wave -->  Electromagnetic waves are created by a fusion of electric and magnetic fields. The light you see, the colours around you are visible because of electromagnetic waves.

-

What is electricity?

Electricity is the flow of electrical power or charge.

-

Discuss what is electromagnetism.

Electromagnetism is a branch of physics that is about the electromagnetic force that is between electrically charged particles. Electromagnetism is the basic reason why the electrons are bound to the nucleus and responsible for the complete structure of the nucleus!

Draw the structure of the neutral product formed in the reaction of dimethyl malonate and methyl vinyl ketone.
Dmitriy789 [7]

Answer:

Explanation:

The reaction between dimethyl malonate which is an active methylene group with an (∝, β-unsaturated carbonyl compound) i.e methyl vinyl ketone is known as a Micheal Addition reaction. The reaction mechanism starts with the base attack on the β-carbon to remove the acidic ∝-hydrogens and form a carbanion. The carbanion formed(enolate ion) attacks the methyl vinyl ketone(i.e. a nucleophilic attack at the β-carbon) to give a Micheal addition product, this is followed by the protonation to give the neutral product.

The electron configuration of bromine is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5 classify electrons in each.
bulgar [2K]

Bromine has the following electron configuration: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5. categorize the electrons in each. Answer for video: The video player is loaded.

On the periodic chart, row 5, column 7, is where you can find a chemical element that was identified in 1811. It has a proton count of 53 and an atomic mass of 126.9. Iodine's atom, then, contains 53 electrons in the following configuration: 1s2, 2s2, 2p6, 3s2, 3d10, 4p6, 5s2, 4d10, 5p5 (Kr 4d10 5s2 5p5). Cu Z = 29 has an electrical arrangement of 1s2 2s2 2p6 3s2 3p6 3d10 4s1. Copper (Co) has the following electron configuration: 1s2 2s2 2p6 3s3 3p6 4s2 3d7. If a chemist were to refer to Copper by its subshell, they would abbreviate this notation to "3d7."

Draw the major organic substitution product(s) for (2R,3S)-2-bromo-3-methylpentane reacting with the given nucleophile. Indicate
Ede4ka [16]

Answer:

The final product of the reaction is (<em>2S,3S</em>)-2-ethoxy-3-methylpentane.

Explanation:

The given reaction undergoes S_{N}2  mechanism in which the nucleophile attacks the backside and it is substituted by the elimination of bromine.

Due to the backside attack of nucleophile , the inverse in stereo-chemistry is observed.

After the substitution of ethoxy group, the configuration is assigned according to the priority it shows clock wise direction(R) - configuration.

When hydrogen faces the front side , it results shows inverse configuration i.e, S- configuration.

The chemical reaction is as follows.
