This molecule can be synthesized from an alkyne anion and an alkyl bromide. However, there are two ways in which this molecule can be formed. One way uses a higher molecular weight alkyne anion (Part 1) and the other uses a lower molecular weight anion (Part 2). Draw the two versions in the boxes below. Omit spectator ions.
For Part 1: Draw the reactants (i.e., alkyne anion and alkyl bromide) needed for the pathway that uses a higher molecular weight alkyne anion:
For Part 2: Draw the reactants (i.e., alkyne anion and alkyl bromide) needed for the pathway that uses a lower molecular weight alkyne anion:
Answers
Answer:
See explanation below
Explanation:
First of all, we need to know the molecule that need to be synthesized. In the first picture attached, we have the molecule.
Now, according to that, the molecule can be formed in two ways. Both ways are rather different but we have one thing in common in both ways, and it's the fact that both ways requires the reaction with an alkyne. In one way, with the higher MW and the other with the lowest.
For the first way, when we need to use the higher MW, all we need to do is to put the triple bond in the highest molecule, in this case, a molecule that include the benzene ring, and the other reactant will be the alkyl bromide. You can see the picture of this product below, (Picture 2).
For the second way, the triple bond should be located in the lowest MW, in this case an ethyl group, instead of the benzene ring, and the molecule with the benzene ring would have the bromide. In both cases we will have the same product. See picture 2 for this.

Perform each conversion
5.88 dL to liters
Answers
Answer:
5.88 dL = 0.588 litre
Explanation:
We need to find a conversion from 5.88 dL to liters.
We know that the conversion is as follows :
1 deciliter = 0.1 litre
To find 5.88 dL to liters, we use the unitary method. So,
5.88 dL= (0.1×5.88) litre
5.88 dL = 0.588 litre
So, there are 0.588 liters in 5.88 dL.

Rotation about C-C single bonds allows a compound to adopt a variety of _____________. conformations configurations formations isomers projections are often used to draw the various conformations of a compound. conformations are lower in energy, while conformations are higher in energy. The difference in energy between staggered and eclipsed conformations of ethane is referred to as strain. strain occurs in cycloalkanes when bond angles deviate from the preferred °. The conformation of cyclohexane has no torsional strain and very little angle strain. The term "ring flip" is used to describe the conversion of one conformation into the other. When a ring has one substituent the equilibrium will favor the chair conformation with the substituent in the position.
Answers
Answer:
Conformation
Explanation:
Conformation refers to "any of the spatial arrangements which the atoms in a molecule may adopt and freely convert between, especially by rotation about individual single bonds"(Oxford dictionary).
Carbon-Carbon single bonds are known to undergo rotations about its axis. These rotations leads to various conformations. The energy difference between conformations may be low or high depending on the structure of the molecule. The difference in energy between conformations determines a molecules's preferred conformation.

54.1miles/gallons how many liters of gas will be consumed traveling 132 km
Answers
Answer:
5.75 L.
Explanation:
From the question given above, the following data were obtained:
Rate = 54.1 miles/gallons
Distance = 132 km
Volume (in L) consumed =?
Next, we shall convert 132 km to mile. This can be obtained as follow:
1 km = 0.621 mile
Therefore,
132 km = 132 km × 0.621 mile / 1 km
132 km = 81.972 mile
Next, we shall determine the volume (in gallons) of the gas needed. This can be obtained as follow:
Rate = 54.1 miles/gallons
Distance = 81.972 mile
Volume (in gallon) =?
Rate = Distance / volume
54.1 = 81.972 / volume
Cross multiply
54.1 × volume = 81.972
Divide both side by 54.1
Volume = 81.972 / 54.1
Volume = 1.52 gallon.
Finally, we shall convert 1.52 gallon to litre (L). This can be obtained as follow:
1 gallon = 3.785 L
Therefore,
1.52 gallon = 1.52 gallon × 3.785 L / 1 gallon
1.52 gallon = 5.75 L
Therefore, 5.75 L of the gas will be consumed.

Use the Henderson-Hasselbalch equation, eq. (3), to calculate the pH expected for a buffer solution prepared from this acid and its conjugate base, assuming: the mass of the weak acid is 0.2 g and the mass of the conjugate base is 0.2 g will be added to 25 mL of water. Also assume the molar mass of the weak acid is 234 and its conjugate base is the sodium salt.
Answers
Answer:
[tex]pH=4.56[/tex]
Explanation:
Hello there!
In this case, given the Henderson-Hasselbach equation, it is possible for us to compute the pH by firstly computing the concentration of the acid and the conjugate base; for this purpose we assume that the volume of the total solution is 0.025 L and the molar mass of the sodium base is 234 - 1 + 23 = 256 g/mol as one H is replaced by the Na:
[tex]n_{acid}=\frac{0.2g}{234g/mol}=0.000855mol\\\\n_{base}= \frac{0.2g}{256g/mol}=0.000781mol[/tex]
And the concentrations are:
[tex][acid]=0.000855mol/0.025L=0.0342M[/tex]
[tex][base]=0.000781mol/0.025L=0.0312M[/tex]
Then, considering that the Ka of this acid is 2.5x10⁻⁵, we obtain for the pH:
[tex]pH=-log(2.5x10^{-5})+log(\frac{0.0312M}{0.0342M} )\\\\pH=4.60-0.04\\\\pH=4.56[/tex]

Which hand is negatively charged?

Option B is the correct answer .
What is Charge ?
Charge is a basic property of matter that is associated with the presence or absence of electrons. Objects can have positive or negative charge, or they can be neutral, which means they have an equal number of positive and negative charges. In physics, charge is one of the fundamental concepts used to explain the behavior of matter and energy in the universe. The interaction between charges is described by Coulomb's law, which states that the force between two charges is proportional to the product of their charges and inversely proportional to the square of the distance between them.

Which element has a larger atomic size? Nitrogen or phosphorus, explain how you know.
Answers
Explanation:
The elements nitrogen and phosphorus are in the same Group 15 with nitrogen being higher, so for the neutral atoms, N with its outer electrons in the n = 2 level would have a smaller radius than P with its outer electrons in the n = 3 level. ... (a) N3- has the largest radius.
On the periodic table, nitrogen and phosphorus can both be found in group 15, with nitrogen in period two and phosphorous in period three. This indicates that phosphorus has more electron shells occupied than nitrogen. Thus, nitrogen's atomic size will be lowered.
What is atomic size ?A chemical element's atomic radius, which is typically the average or typical distance between the nucleus's core and the outermost isolated electron, serves as a gauge for the size of an atom. Considering that the boundary is not a clearly defined physical object.
Atomic radii in the periodic table decrease across a row from left to right and increase across a column from top to bottom. Due to these two patterns, the periodic table's lower left and upper right corners, respectively, contain the largest and smallest atoms.
The size of the atom or ion is determined by the size of the largest filled orbital because electrons are what occupy space in atoms.
Thus, nitrogen's atomic size will be lowered.
