Electronic configuration Mg(12) = 1s22s22p63s2

Al(13) = 1s22s22p63s23p1

Mg has a more stable configuration and hence requires more energy to remove an electron from 3s. electron affinities become more negative from left to right across a row in the periodic table.

The complete electronic configuration of Mg is 1s22s22p63s2 whereas the complete electronic configuration of Al is 1s22s22p63s23p1

Removing an electron from the 3s orbital of Mg requires more energy than removing an electron from the 3p orbital of Al.

However, when adding an electron, the electron affinity for Mg is less negative than that of Al because the electron is being added to the 3p sublevel.

The symbols used to describe electron configurations begin with the shell number, followed by the orbital type, and finally, a superscript indicating the number of electrons in the orbital.

A. Liquid A has a higher boiling point.

The boiling point of the solution is usually higher than that of the pure solvent. This is due to the increase in vapor pressure required to overcome the attraction between the solute and solvent molecules.

This phenomenon, known as boiling point elevation, is more pronounced in solutions with high solute concentrations. Therefore, solution A is expected to have a higher boiling point than solution B, which has a higher concentration of water.

Alternatively, you can calculate the boiling points of two solutions using the boiling point elevation formula:

ΔTb = Kb x molarity

where ΔTb is the change in boiling point, Kb is the boiling point rise constant of the solvent, and molarity is the concentration of the solute in moles per kilogram of solvent. By substituting the corresponding values ​​for the two solutions, you can determine which solution has the higher boiling point.

The correct answer is b. P atoms introduce additional mobile positive charges.

Silicon crystals are semiconductors, which means that they have intermediate electrical conductivity compared to metals and insulators. When a small fraction of Si atoms is replaced with atoms of a different element, such as phosphorus (P), the conductivity of the Si crystal can increase.

This is because P atoms introduce additional mobile positive charges, or holes, into the crystal. Holes are areas where an electron is missing, and they can move through the crystal just like electrons. As a result, the presence of holes can increase the overall conductivity of the crystal.

a. P atoms introduce additional mobile negative charges is incorrect because P atoms actually introduce positive charges, or holes, into the crystal.

c. Ge atoms have more electrons than Si atoms is incorrect because this would actually decrease the conductivity of the crystal, as there would be more electrons available to fill the holes and reduce the overall mobility of charge carriers.

The inhibitors of Ca release by the ER, nitric oxide and guanylyl cyclase, interfere with smooth muscle cell relaxation. Correct answer: letter D.

All of these inhibitors interfere with smooth muscle cell relaxation, because they disrupt the calcium signaling pathway, which is responsible for the contraction and relaxation of smooth muscle cells. Nitric oxide inhibits the release of calcium from the endoplasmic reticulum, guanylyl cyclase decreases the production of cyclic GMP which is necessary for calcium release from the ER, and calcium channel blockers prevent calcium from entering the cell.

Nitric oxide works by binding to guanylyl cyclase, an enzyme found on the surface of smooth muscle cells. This binding triggers the enzyme to produce cyclic guanosine monophosphate (cGMP), which in turn causes the relaxation of smooth muscle cells.

However, when calcium is released from the endoplasmic reticulum (ER), it can interfere with the binding of nitric oxide to guanylyl cyclase, preventing the production of cGMP. As a result, the smooth muscle cells are unable to relax, leading to a decrease in smooth muscle cell dilation.

When nitric oxide is used in the dilation of smooth muscle cells, which of the following would interfere with the relaxation of the smooth muscle cells? Inhibitors of:

A) Ca release by ER.

B) Ntric oxide.

C) Guanylyl cyclase.

As for what eats the deer, there are many potential predators depending on the location and environment of the meadow. In some areas, predators of deer could include wolves, coyotes, cougars, or bears. In other areas, deer may be hunted by humans. In addition, some birds of prey, such as eagles or hawks, may also prey on deer, particularly fawns or other young deer.

Explanation:

Answer:

Explanation:

CH3-CH2-CH=CH-CH3 is a molecule with a long carbon chain containing a double bond between the third and fourth carbon atoms. In this molecule, the first three carbon atoms (CH3-CH2-CH) form a substructure known as a propyl group, while the last two carbon atoms (CH=CH-CH3) form a substructure known as an allyl group.

When applying Markovnikov's rule to this molecule, the double bond is treated as a functional group that can react with other molecules. In this case, the double bond will react with a molecule of hydrogen to form a new carbon-hydrogen bond, with the hydrogen atom attaching to the carbon atom that already has the most hydrogens. In this molecule, the carbon atom in the propyl group has three hydrogens, while the carbon atom in the allyl group has only two hydrogens. Therefore, according to Markovnikov's rule, the hydrogen atom will react with the carbon atom in the allyl group, forming a new molecule with the following structure: CH3-CH2-CH-CH2-CH3.

Alternatively, if the reaction follows anti-Markovnikov's rule, the hydrogen atom will react with the carbon atom in the propyl group, forming a new molecule with the following structure: CH3-CH2-CH2-CH=CH3. This is the opposite of what would happen under Markovnikov's rule, as the hydrogen atom attaches to the carbon atom with the fewest hydrogens instead of the most.

Overall, Markovnikov's rule and anti-Markovnikov's rule describe how double bonds in molecules can react with other molecules to form new bonds. These rules help predict the outcome of chemical reactions involving double bonds, and are important tools in organic chemistry.

If some hydrogen gas escapes during the reaction, it will affect the reported percentage of aluminum in the sample.

The hydrogen gas that escapes will reduce the total volume of gas in the apparatus, which will in turn reduce the number of moles of gas that are produced by the reaction. Since the number of moles of gas produced is used to calculate the percentage of aluminum in the sample, a reduction in the number of moles of gas will result in a lower reported percentage of aluminum in the sample. Therefore, if hydrogen gas escapes during the reaction, the reported percentage of aluminum in the sample will be less than its actual percentage.
