Select the correct name for the following compound, including the correct (E) or (Z) designation where appropriate. A) (E)-5-ethyl-2-methyl-5-heptene
B) (Z)-5-ethyl-2-methyl-5-heptene
C) (E)-3-ethyl-6-methyl-2-heptene
D) (Z)-3-ethyl-6-methyl-2-heptene
Answers
Correct name for the compound is (Z)-3-ethyl-6-methyl-2-heptene, which corresponds to option D.
Let's discuss it further below.
To determine the correct name for the compound, follow these steps:
1. look for longest carbon chain containing the double bond. In this case, it is a 7-carbon chain, making it a heptene.
2. Count the carbon atoms in the chain, starting from the end closest to the double bond. The double bond is between carbons 2 and 3.
3. Look for the substituents and their positions on the carbon chain. There is an ethyl group on carbon 3 and a methyl group on carbon 6.
4. Determine the (E) or (Z) designation of the double bond. If the two higher priority groups are on the same side of the double bond, it is (Z). If they are on opposite sides, it is (E). In this case, the ethyl and methyl groups are on the same side, so it is (Z).
Putting it all together, the correct name for the compound is (Z)-3-ethyl-6-methyl-2-heptene, which corresponds to option D.

Wood is made mostly of cellulose and has a chemical formula of C.H.00. Which of the following equations
represents the cellulose combustion reaction?
Answers
Answer:
Option B.
C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O
Explanation:
To know which option is correct, we shall write the balanced equation for the combustion of cellulose. This is illustrated below:
C₆H₁₀O₅ + O₂ —> CO₂ + H₂O
There are 6 atoms of C on the left side and 1 atom on the right side. It can be balance by writing 6 before CO₂ as shown below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + H₂O
There are 10 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 5 before H₂O as shown below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + 5H₂O
There are a total of 7 atoms of O on the left side and a total of 17 atoms on the right side. It can be balance by writing 6 before O₂ as shown below:
C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O
Now, the equation is balanced.
Thus, option B gives the correct answer to the question.

Answers
Explanation:
People also ask
What is the importance of nitrogen for plants?
Nitrogen is an essential macronutrient for plant function and is a key component of amino acids, which form the building blocks of plant proteins and enzymes. Proteins make up the structural materials of all living matters and enzymes facilitate the vast array of biochemical reactions within a plant.
Answer:
Nitrogen is vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide(i.e.,photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.

Convert particles to moles: 8.3 x 10^20 atoms Cu
Answers
Answer:
\(\boxed {\boxed {\sf 0.0014 \ mol \ Cu}}\)
Explanation:
We are asked to convert particles to moles.
1. Avogadro's Number1 mole of any substance contains the same number of particles (atoms, molecules, formula units). This is Avogadro's Number or 6.022*10²³.
In this problem, the particles are atoms of copper. So, 1 mole of copper contains 6.022*10²³ atoms of copper
2. Convert Atoms to MolesUse Avogadro's Number to make a ratio.
\(\frac{ 1 \ mol \ Cu}{ 6.022*10^{23} \ atoms \ Cu}\)
We are trying to convert 8.3*10²⁰ atoms of copper to moles, so we multiply that value by the ratio.
\(8.3*10^{20} \ atoms \ Cu*\frac{ 1 \ mol \ Cu}{ 6.022*10^{23} \ atoms \ Cu}\)
The units of "atoms Cu" will cancel.
\(8.3*10^{20}\frac{ 1 \ mol \ Cu}{ 6.022*10^{23} }\)
Condense the expression into 1 fraction.
\(\frac{8.3 *10^{20}}{ 6.022*10^{23} } \ mol \ Cu\)
\(0.001378279641 \ mol \ Cu\)
3. RoundThe original measurement of atoms has 2 significant figures, so our answer must have the same. For the number we calculated that is the ten-thousandths place.
0.001378279641The 7 in the hundredth thousandth place tells us to round the 3 up to a 4.
\(0.0014 \ mol \ Cu\)
8.3*10²⁰ atoms of copper are equal to 0.0014 moles of copper.

are there few or many nuclei at the end plate
Answers
Answer:
There is a cluster of nuclei.
Explanation:
it allows for production of the large amounts of proteins and enzymes needed for maintaining normal function of these large protein dense cells.
At the end plate of a capacitor, there are usually few nuclei. This is because the end plate is a conductor and its purpose is to store and disburse electric charge.
The nuclei that are present at the end plate are usually the result of impurities that may be present in the conductor material. These impurities can be from the manufacturing process or from environmental exposure to elements that can cause particles to adhere to the end plate.
In order for the capacitor to work correctly, these nuclei should be kept to a minimum. This can be done by using a high-quality conductor material and by treating the end plate with a special coating or sealant. This helps to prevent the accumulation of impurities that can interfere with the capacitor’s performance.

For each pair of newman projections, select the conformer with higher energy
Answers
The conformer with the highest energy should be chosen for each pair of Newman projections. A Newman projection, which is helpful in alkane stereochemistry.
shows how a chemical bond will behave from front to back, with a line denoting the front atom and a circle denoting the back carbon. Newman projection is a type of representation used in organic chemistry to visualize the conformations of molecules, particularly those with multiple carbon-carbon bonds. It shows a "bird's eye view" of the molecule along a chosen carbon-carbon bond, with one carbon atom represented as a dot and the other carbon atom represented as a circle. The projection also shows the relative positions of the substituent groups attached to the carbons in the molecule, allowing for the visualization of different conformations of the molecule.
Newman projections are often used to study the potential energy of different conformations of a molecule, as the torsional strain caused by the interaction between the substituent groups can affect the stability and reactivity of the molecule. By rotating the molecule around the carbon-carbon bond axis, one can visualize and compare different conformations and predict which ones are most stable or reactive.

the movement of which ion through leakage channels establishes the negative membrane potential?
Answers
The movement of potassium ions through leakage channels is responsible for establishing the negative membrane potential. These leakage channels are present in the cell membrane of most cells and allow a slow and constant movement of ions across the membrane.
As potassium ions have a higher concentration inside the cell than outside, they tend to move out of the cell through these channels, causing a slight negative charge to develop inside the cell. This negative charge, or membrane potential, is essential for many cellular processes, including the transmission of nerve impulses and the contraction of muscle fibers.
Other ions, such as sodium and calcium, also contribute to the membrane potential, but their movements are regulated by ion channels and pumps. In summary, the movement of potassium ions through leakage channels establishes the negative membrane potential, which is critical for the proper functioning of cells.

the term used for the space between two metal pieces at the bottom of the joint to be welded is ____ opening.
Answers
The term used for the space between two metal pieces at the bottom of the joint to be welded is "root opening."
The root opening in welding plays a crucial role in achieving a successful and strong weld joint. It refers to the gap or space intentionally created between the two metal pieces that are to be joined together. This gap is typically located at the root of the joint, which is the junction between the two base metals.
The root opening is the gap or space intentionally left between the metal pieces to allow for proper fusion and penetration of the weld bead.
