Answer : It helps to control the levels of alertness.

Explanation : Neurotransmitters are endogenous chemicals which enables neuro-transmission. It is a type of a chemical messenger which allows to transmit signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell. It helps to maintain the level of alertness in the body by maintaining the chemical synapse when required.

Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as a hormone and neurotransmitter. The name "noradrenaline," derived from Latin roots meaning "at/alongside the kidneys," is more commonly used in the United Kingdom; in the United States, "norepinephrine," derived from Greek roots having that same meaning, is usually preferred. "Norepinephrine" is also the international nonproprietary name given to the drug.Regardless of which name is used for the substance itself, parts of the body that produce or are affected by it are referred to as noradrenergic.

Phosgene is formed from carbon monoxide and chlorine. At 611 oC, Kc is approximately 16.5 M-1 or L/mol. Calculate Kp (in atm-1)

defon

Answer:

Kp is 0.228/atm

Explanation:

This is the reaction:

CO + Cl₂ → CCl₂O

1 mol of carbon monoxide and 1 mol of chlorine produce 1 mol of phosgene.

Formula for Kp which derivates from Kc is:

Kp = Kc (R.T)ⁿᵇ ⁻ ⁿᵃ

Δп = nb (moles in the products) - nₐ(moles in the reactants)

Δп = 1 - 2 = -1

T is T° in K → T°C + 273 = 611°C +273 = 884K

R → Universal constant gas → 0.082 L.atm/mol.K

We replace the data: Kp = 16.5 L/mol (0.082 . 884K)⁻¹ → 0.228/atm

In chemistry class, a student conducted an investigation on the factors that affect the solubility of copper (II) sulfate (CUSO)

beks73 [17]

Answer:

See Explanation

Explanation:

The rate of a chemical reaction depends on certain factors. Some of these factors include; surface area, temperature, nature of reactants etc.

The trial that exhibits the slowest rate of dissolution of CuSO4 crystals is trial 2 because the crystals have a small surface area since the crystals were large. Also, the solution was not agitated or stirred to increase the rate of collision between the water and the CuSO4 crystals.

Increase in temperature, agitation of the reaction solution and high surface area increases the rate of collision between the water and CuSO4 crystals leading to a faster rate of dissolution. This occurs in trial 3.

Answer:

Throughout your job search, you’ll find that education is closely related to the career of your choosing. It’s important to take the time to find out what to expect now, so you can start developing the skill that you need to excel in that career.

Explanation:

At the time of attending our interview, we find that the question raised from an interviewer related to the choosing of the field and from our educational background. So, it clearly based on what we learn via our education and how we can get connected to the selected field but not based on our salary or an economy.

Similarly, it is essential to make a note about the requirement from the chosen field and have to prepare our skill accordingly. It means that required to develop the knowledge related to our selective field and should be presented in a connected way in front of an interviewer.
