draw the product of the sn2 reaction and indicate stereochemistry. write the inorganic product in the answer palette.
SN2 reaction proceeds with inversion of configuration at the reacting carbon atom. The product has a different configuration at this carbon atom from the product.
SN2 reaction is a short form for substitution nucleophilic bimolecular reaction. It is a synchronous reaction in which the leaving group departs at the same time as the nucleophile attacks in a single transition state.
Recall that SN2 reaction proceeds with inversion of configuration hence the product has a different configuration at the reacting carbon atom from the product. The inorganic product in this reaction is HI. The organic product is shown in the image attached to this answer.

3) The compound is soluble in water.
A) 1 2 and 3
B) 1 and 2 only.
C) 1 and 3 only
D) 2 and 3 only
Answer:

Explanation:
1 ) is correct because,
K donates 1 electron
F gain 1 electron from K.
If donating and gaining of electrons takes place between two electron, then type of compound formed is ionic.
2 ) is correct because,
K + F -----> KF
3 ) is correct because,
KF is soluble in cold water; very soluble in hot water.

Answer:
protons and neutrons
Explanation:
Neutrons and protons are the particles that are found in the nucleus of an atom.
What are protons and neutrons?Protons and neutrons are subatomic particles. They are present in the nucleus of an atom and constitute most of the mass of the atom. There are three kinds of subatomic particles that are present in an atom.
These are -
Electrons: Electrons are negatively charged particles. These are present in the atomic shells of the atom. The number of electrons in the last shell of the atom constitutes the valency of the atom. Protons: Protons are positively charged particles. These are present in the nucleus of the atom.Neutrons: Neutrons are neutral molecules with no charge. These are also present in the nucleus of the atom.Since most of the mass of the atom, in the form of protons and neutrons, is present in the nucleus, the mass number is denoted as the sum of the number of protons and neutrons. Protons and neutrons together are sometimes also called nucleons.
Therefore, neutrons and protons are present in the nucleus of an atom.

calculate the kinetic energy of a baseball (mass = 5.25 oz) with a velocity of 1.0 x 10^2 mi/h
Answer:
262.5 Joules
Explanation:
You find the kinetic energy of multiplying half of the mass by the velocity. In this word problem it tells you the mass so you divide it by 2. That answer is 2.625, you then multiply that by the velocity, in this instance it's 1.0 x 10^2 mi/h.
The unit in kinetic energy is Joules. This is actually a really important part in chemistry and physics.
The kinetic energy of a baseball (mass = 5.25 oz) with a velocity of 1.0×10² mi/h is 147.88 joules.
How do we calculate kinetic energy?Kinetic energy of any object will be calculated by using the below equation:
K.E. = 1/2(mv)², where
m = mass of object in kg = 5.25 oz = 0.148 kg
v = velocity in m/sec = 1.0×10² mi/h = 160934 m/h = 44.704 m/s
On putting values on the above equation, we get
K.E. =1/2(0.148)(44.704)²
K.E. = 147.88 joules
Hence required kinetic enrgy is 147.88 joules.

Atomic # 6 6
Atomic mass 12 13
protons 6 6
neutrons 6 7
electrons 6 5

the atomic # of both is 6, so they are both carbon with 6 protons
element 1 has a total of protons plus neutrons of 12, element 2 of 13
so element 1 has 6 neutrons,element 2 has 7
element 2 has a +1 charge with 6 protons, so it has only 5 negative electrons
element 1 with 6 protons has 6 electrons, so it has a 0 charge
6. Haydee prepared a solution with 3mL of potassium chloride (KCl) in 200 mL of water is prepared. Calculate the percent by volume concentration of the solution.
A. 1.46% B.1.48 %
C. 1.49 % D. 1.50%
Considering the definition of percent by volume concentration, the correct answer is option D: the percent by volume concentration of the solution is 1.50%
Percent by volume concentration is a measure of concentration that indicates the volume of solute per 100 volume units of the solution. This value is calculated by dividing the volume of the solute by the total volume of the solution, and multiplying by 100 to express it as a percentage:
[tex]percent by volume concentration=\frac{volume of solute}{total volume of the solution}x100[/tex]
In this case, you know:
volume of solute= 3 mLtotal volume of the solution= 200 mLReplacing in the definition of percent by volume concentration:
[tex]percent by volume concentration=\frac{3 mL}{200 mL}x100[/tex]
Solving:
percent by volume concentration=0.015×100
percent by volume concentration=1.50
Finally, the correct answer is option D: the percent by volume concentration of the solution is 1.50%

Assume that wave B has a wavelength of 415 nm. Calculate the frequency of the wave. The value for c is 3.00 x 10 8 m/s. The wavelength of wave A is [__________]Hz.
The wave B has wavelength of 415 nm. The value for c is 3.00 x 10 8 m/s. The frequency is 7.22 x 10¹¹ Hz.
What is frequency?Frequency is defined as the number of waves passing through a fixed point in a given amount of time.
The frequency can also be defined as a repeated event is the number of occurrences per unit of time.
Frequency can be expressed as
f = c / ∧
Where c = 3.00 x 10⁸ m/s
∧ = 415 nm
So, f = 3.00 x 10⁸ m/s x 415 nm
f = 7.22 x 10¹¹ Hz.
Thus, the wave B has wavelength of 415 nm. The value for c is 3.00 x 10 8 m/s. The frequency is 7.22 x 10¹¹ Hz.

1. Imagine doing the same virtual experiment using wood as the bottom material, instead of glass or water. Predict how the light would interact with the wood.
The wood can't do the same function as done by the water and glass in the same virtual experiment due to its different chemical composition.
The light will not pass through the wood due to its translucent behaviour that prevents light to pass through it as compared to water and glass which are transparent materials and light can easily pass through it.
So using wood as a bottom material instead of glass and water will not perform the same function as perform by water and glass in the same virtual experiment so we can conclude that wood can't perform the same function in the experiment.
