Identify arrows pointing to structures containing pi bonds.

Answers

Answer 1

I believe the question is asking you to draw arrows pointing to all of the pi bonds in the chemical structure. The first bond between two atoms is referred to as a sigma bond while additional bonds (double or triple bonds) are referred to as pi bonds.

Answer 2

The arrows pointing to the structures containing pi bonds can be seen in the image attached below. From the assumed example Butan-1,3-diene , there are two pi bonds.

A bond is an attractive force designated by a dash (---) that holds atoms or ions mutually in a chemical bonding.

Covalent bonds exist in organic chemistry and they are of two types:

sigma bond σ -bondpi bond π-bond

The sigma bond (σ) exists as a single bond that occurs by the overlapping of an s-s atomic orbital or s-p atomic orbital. They can be seen in unsaturated straight chains such as alkane.

The pi bond (π) exists as a double bond or a triple bond that occurs by the overlapping of two unhybridized p-orbitals.

Since the diagram is not given, we use Butan-1,3-diene as an example of the required structure.

From the structure which is attached in the diagram below, we can see that there are two double bonds indicating the presence of pi-bonds.

Therefore, we can conclude that from the assumed example Butan-1,3-diene, there are two pi bonds.

Which condition must be met for conduction to occur?

particles must be large
particles must be small
particles must be in contact
particles must be spread apart

Answers

Yeah she will be particles must be in contact

The condition that must be met for conduction to occur is particles must be in contact. Therefore, the correct option is option C.

What is conduction flow of heat?

A pan heats up when you place it on the flame. It's because heat is transferred from the burner to the pan. Also, it allows any other utensil or pan to heat up. Yet after a while, the vessel cools down when you remove it from the heat. That happens because the vessel's heat is dissipated onto the surrounding area.

It enables the vessel to cool. Heat is passed from a warm object towards the cold object in both situations. Typically, it occurs in every situation. Conduction is the process through which heat is transported from one object's hot end to its cool end. The condition that must be met for conduction to occur is particles must be in contact.

Therefore, the correct option is option C.

Answers

Answer:

V₂ = 8.8 L

Explanation:

Given data:

Initial volume = 8.5 L

Initial temperature = 294 K

Final temperature = 305 K

Final volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁

V₂ = 8.5 L × 305 K / 294 k

V₂ = 2592.5 L.K / 294 K

V₂ = 8.8 L

What is S for ClO3, the
chlorate ion?

Answers

Answer:

The chlorate anion has the formula ClO⁻ ₃. In this case, the chlorine atom is in the +5 oxidation state. "Chlorate" can also refer to chemical compounds containing this anion; chlorates are the salts of chloric acid.

"S" typically represents the oxidation state or oxidation number of an element in a chemical compound. For the chlorate ion (ClO₃⁻), the oxidation state of chlorine (Cl) is +5.

The oxidation number, also known as the oxidation state, of an element in a chemical compound is a numerical value that indicates the electron distribution and the degree of electron loss or gain by an atom in a chemical reaction. It helps to identify the type of chemical bonding and the role of each element in the compound.

The chlorate ion (ClO₃⁻) has a chemical formula of ClO₃⁻ where:

Cl: Chlorine has an oxidation state of +5 since oxygen (O) is known to have an oxidation state of -2 and the overall charge of the ion is -1.

O: Oxygen has an oxidation state of -2.

So, the oxidation state of chlorine in the chlorate ion is +5.

Ava observes that a certain species of bird follows behind a herd of cattle. The bird species primarily eats insects. The birds stay with the herd of cattle as they graze. What is a scientific hypothesis that Ava could formulate based on her observations?

Answers

Answer:

There are insects associated with the cattle herd that serve as food for Ava.

Explanation:

The most logical hypothesis to deduce from the observation would be that the cattle herd has a kind of association with insects that happen to serve as food for the birds.

Usually, the body of cattle is plagued with different species of parasitic insects which obtain their foods and shelters from the animal. These parasitic insects will definitely be a food source for insect-predating birds. Hence, it follows logically that the Ava birds lurk behind the herd of cattle scouting for insects on the body of the cattle.

If Chicago had experienced its average highest temperature
in August, which month would have had the longest day? Explain your
reasoning.

Answers

I think there is a trick in the question because the most know day as longest is in June 21 before August. So I think it must be “ Chicago had experienced its average highest temperature in August, so in June 21 would be a longest day, because its during summer and there is cold weather from August, this mean the days are more short.” I hope is right :).

If Chicago had experienced its average highest temperature in August, the longest day remains the same and that is the 21st of June.

What is the effect of temperature on the length of the day?

The effect of temperature induces the combination of more direct rays of the sunlight as the result of the tilting of the earth's hemisphere towards the sun to receive more solar energy and possess a warmer temperature.

But the temperature of a particular region also depends on the humidity and other abiotic parameters. So, if Chicago had experienced its average highest temperature in August, it does not mean that the longest day is in the month of August. It will remain, as usual, i.e 21 June.

Therefore, if Chicago experienced its average highest temperature in August, the longest day remains the same and that is the 21st of June.

Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave.

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
