What is overexcitability of CNS?

Answers

Answer 1

Overexcitability of the central nervous system (CNS) is a condition in which the CNS is overly sensitive and reactive to stimuli.

This can lead to a variety of symptoms, such as hyperactivity, restlessness, and difficulty concentrating. Overexcitability of the CNS can be caused by a number of factors, including genetic predisposition, neurological disorders, and exposure to certain medications or substances.

Treatment for overexcitability of the CNS typically involves addressing the underlying cause of the condition, as well as implementing behavioral strategies to help manage symptoms.

What is electron dot structure?

Electron dot structure is defined as the graphical representations of the chemical bonds that hold atoms in molecules together. Additionally, they show how many lone pairs there are in total among all the atoms that make up the molecule. The amount of electron pairs shared by two atoms determines how many bonds are created between them. Two electrons make up an electron pair.

Answer: 2.1 moles NH3

What periodic trend does the atomic radius follow? A. It decreases from top to bottom. B. It increases from left to right. C. It stays the same across the table. D. It decreases from left to right.

Answers

Answer and Explanation:

The correct answer is B. The atomic radius increases from left to right across the periodic table.

There are a few factors that contribute to this trend. As you move from left to right across a period (horizontal row), the atomic number increases, meaning there are more protons in the nucleus. The increase in positive charge in the nucleus exerts a stronger pull on the electrons present in the same energy level, causing the electron cloud to be pulled closer to the nucleus.

Additionally, as you move from left to right across a period, the number of energy levels or shells remains mostly constant, while the number of protons and electrons increases. The increase in electron-electron repulsion forces the electrons to spread out over the same energy levels, thus increasing the size of the electron cloud and atomic radius.

However, it is important to note that when moving down a group (vertical column), the atomic radius generally increases. This is because each subsequent row adds a new energy level or shell, increasing the average distance between the nucleus and the outermost electrons. The additional energy levels contribute to shielding the outer electrons from the pull of the nucleus, leading to a larger atomic radius.

So, the atomic radius trend in the periodic table is that it generally increases from left to right across a period and increases from top to bottom within a group.

Mercury poisoning is a debilitating disease that is often fatal. In the human body, mercury reacts with essential enzymes leading to irreversible inactivity of these enzymes. If the amount of mercury in a polluted lake is 0.4 Hg/mL, what is the total mass in kilograms of mercury in the lake

Answers

Answer:

The total mass of mercury in the lake is 631,542.7 kg

Explanation:

Question: The given dimensions of the lake as obtained from a similar question posted online are;

The surface area of the lake, A = 100 mi²

The lake's average depth, d = 20 ft.

The concentration of the mercury, C = 0.4 μg Hg/mL = 0.4 × 10⁻⁶ kg Hg/L

Therefore, we have;

The volume of water mixture in the lake, V = A × d

∴ V = 100 mi² × 20 ft. = 2,787,840,000 ft.² × 20 ft. = 55,756,800,000 ft.³

1 ft³ = 28.31685 L

∴ 55,756,800,000 ft.³ = 55,756,800,000 ft.³ × 28.31685 L/ft.³ = 1.57885675 × 10¹² L

The total mass of mercury in the lake, m = C × V

∴ m = 0.4 × 10⁻⁶ kg Hg/L × 1.57885675 × 10¹² L = 631,542.7 kg

The total mass of mercury in the lake, m = 631,542.7 kg.

which alkyl halide would you expect to react most slowly when heated in aqueous solution?
(I) (CH3)3C-f
(II) (CH3)3C-CI
(III) (CH3)3C-Br
(IV) all of these would react at the same rate
A. I
B. II
C. III
D, V

Answers

The correct answer is C. III, (CH3)3C-Br.

When alkyl halides are heated in aqueous solutions, they can undergo an elimination reaction in which the halogen atom is eliminated along with a proton from the adjacent carbon atom. The rate of this reaction depends on several factors, including the strength of the C-H bond and the strength of the C-X bond (where X is the halogen atom).

In general, the rate of elimination reactions increases as the size of the halogen atom decreases. This is because smaller halogens such as fluorine and chlorine have stronger C-X bonds than larger halogens such as bromine and iodine. Therefore, the alkyl halide with the weakest C-Br bond, (CH3)3C-Br, would be expected to react most slowly when heated in aqueous solution compared to (CH3)3C-F and (CH3)3C-Cl.

Additionally, the (CH3)3C-F and (CH3)3C-Cl alkyl halides have strong C-H bonds due to the electronegativity of fluorine and chlorine, respectively, which makes them less likely to undergo elimination reactions compared to (CH3)3C-Br.

Therefore, the correct answer is C. III, (CH3)3C-Br, which would react most slowly when heated in aqueous solution.

using the periodic table, determine the ion charges of the following elements if valence electrons were removed or added to reach the octet. barium

Answers

Given that the valence electrons were removed or added to the following elements to fulfill the octet, barium's charge would be +2

The octet rule generally refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have lesser than eight electrons, they tend to react and form more stable compounds.

This certainly means that the atom's valence shell has a resemblance with a noble gas. The octet rule states that the atoms like to have eight electrons only in their full outer shells.

In case of barium the valence electronic configuration is [Xe] $6s^{2}$. So here we can see that in order to reach the nobel gas configuration Barium needs to loose only 2 electrons and after that barium will attain Xenon configuration. Hence the charge on Barium would be 2+.

Find the boiling point of a solution of 2.00 m solution of sodium chloride, NaCl, in water (kb= 0.512°C, bp= 100.0°C)

Answers

Answer: Boiling point of the given solution is $102.048^{o}C$.

Explanation:

Given: Molality = 2.00 m

$k_{b} = 0.512^{o}C$

Now, equation for dissociation of water is as follows.

$H_{2}O \rightarrow H^{+} + OH^{-}$

As it is giving 2 ions upon dissociation. So, the value of i = 2.

Formula used to calculate change in temperature is as follows.

$\Delta T = i \times k_{b} \times m$

where,

i = Van't Hoff factor

$k_{b}$ = molal boiling point elevation constant

m = molality

Substitute the values into above formula as follows.

$\Delta T = i \times k_{b} \times m\\= 2 \times 0.512^{o}C \times 2.00 m\\= 2.048^{o}C$

As the boiling point of water is $100^{o}C$. Hence, the boiling point of solution will be as follows.

$\Delta T^{'}_{b} = 100^{o}C + 2.048^{o}C\\= 102.048^{o}C$

Thus, we can conclude that boiling point of the given solution is $102.048^{o}C$.

B. 0.55%(w/v)
C. 3.6 %(w/v)
D. 5.4%(w/v)

Answers

The 0.15% (w/v) solution of glucose (C₆H₁₂O₆) is isotonic with a 0.1 M NaCl solution. Therefore, the correct answer is A. 0.15%(w/v). A solution is isotonic with another solution if the solute concentrations of both solutions are the same.

The molarity of a 0.1 M NaCl solution is 0.1 M, which means that there are 0.1 moles of solute (NaCl) per liter of solution.

To find the molarity of a solution, you can use the formula:
