Which class of organic compound is most likely to be used in anesthetics?

2 answers:

8 0

The class of organic compound is most likely to be used in anesthetics is ethers. The first ether that is used in anesthetics is diethyl ether .

In general anesthetic works on brain, and produce unconsciousness and insensitivity to feel pain or anything. Generally it lowers the sensitivity of the organs. Diethyl ether is the first ether that is used as anesthetics.

Calculate the final temperature of 35 mL of ethanol initially at 20 ∘C upon absorption of 720 J of heat. (density of ethanol =0.

Natalija [7]

The specific heat capacity of ethanol is 2.46 joules per gram.
Now, we may use the equation:
Energy = mass * specific heat capacity * change in temperature

Here we may substitute:
mass = density * volume

Energy = density * volume * specific heat capacity * change in temperature
720 = 0.789 * 35 * 2.46 * ΔT
ΔT = 10.6

The final temperature will be
20 + 10.6
= 30.6 °C

Based on the information given, classify each of the pure substances as elements or compounds, or indicate that no such classifi

Olenka [21]

Answer:

Analysis with an elaborate instrument indicates that:

Substance A contains two elements.

Compound

Substance B and substance C react to give a new substance D.

Insufficient information

Substance E decomposes upon heating to give substance F and substance G.

Compound

Heating substance H to 1000 °C causes no change.

Insufficient information

Substance I cannot be broken down into simpler substances by chemical means.

Element

Substance J cannot be broken down into simpler substances by physical means

Insufficient information

Explanation:

Important background:

Pure substances are elements or compounds.

Elements are formed by only one kind of atoms. They cannot be broken down into another substance by chemical or physical means. There are only 118 known elements; they are all listed in the periodic table.

Compounds have fixed chemical composition and are formed by two or more kind of atoms, chemically bonded. They can be broken down into different pure substances, either elements or other substances, only by chemical changes.

With tha information let's see every statement about the pure substances that should be classified as elements or compounds.

Substance A contains two elements: compound

Since, the pure substance contains two elements, it is not just and element by a compound. This is because a compound is a pure substance composed of two or more elements.

Substance B and substance C react to give a new substance D.: Insufficient information

Either two elements, one element and one compound, or two compounds may react to give a new substance, so you cannot assure what kind of pure substance B and C are.

For instance:

- two elements like hydrogen and oxygen reacto to give water (a compound)

- a compound like CH₂=CH₂ react with an element like Cl₂ to give CH₂Cl-CH₂Cl

Substance E decomposes upon heating to give substance F and substance G. : Compound

An element cannot be decomposed into two different substances, since the elements are composed by just one kind of atoms.

So, if the substance E decomposes into two different substances, F and G, E necessarily has to be a compound.

Heating substance H to 1000 ∘C causes no change. Insufficient information

The mere fact that a substance has not changed by heating at such extreme temperature cannot assure whether the substance is a compound or an element.

Some compounds are stable at very high temperatures. For instace, magnesium oxide, MgO, has a melting point of 2852°C, meaning that it will remain a a solid substance way beyond 1,000°C

Substance I cannot be broken down into simpler substances by chemical means. Element

Since an element is formed by one single kind of atoms, it cannot be broken down into simpler substances by chemical means; but a compose does, because it is formed by two or more different elements chemically bonded.

Substance J cannot be broken down into simpler substances by physical means: Insufficient information

The distintion between compounds and elements is based on chemical changes; the fact that physical changes do not change the substance does not tell anything about the fact that the substance is composed by one kind of elements or several elements chemical boonded.

Hence, physical means do not provide sufficient information to conclude about whether a substance is an element or a compound.

Which species is oxidized in the reaction below? al2o3(s) 3 co(g) → 2 al(s) 3 co2(g)

Elza [17]

Al species is oxidized in the reaction below al2o3(s) 3 co(g) → 2 al(s) 3 co2(g by oxidation

The reaction brought on by coming into touch with oxygen molecules is known as oxidation. These materials can be non-metals like live tissues or metals. Technically speaking, oxidation is the loss of one electron during the phase of interaction between two or more atoms.

Initially, the word "oxidation" was used to refer to chemical processes in which an element reacts with oxygen. An illustration of this is the oxidation of magnesium in the formation of magnesium oxide when magnesium metal and oxygen react.

The biological oxygen demand (BOD) of wastewater is decreased after oxidation, which also lessens some contaminants' toxicity. Some contaminants undergo this treatment and are transformed into carbon dioxide, water, and biosolids. Disinfection is commonly accomplished using chemical oxidation.

In what orbital would to valence electrons of strontium be found? a.) 5s b.) 4s c.) none d.) 5p

KonstantinChe [14]

Answer:

The correct answer is 5s

Explanation:

Strontium atomic number = 38

Electronic configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 3d^{10} 4s^{2} 4p^{6} 5s^{2}$

As $5s$ orbital is valence orbital in strontium, the outer electrons exists in that orbital only.
