Draw the bridged bromonium ion that is formed as an intermediate during the bromination of this alkene. Include hydrogen atoms, nonbonding electrons, and formal charge(s) in your structure. The starting alkene is a 4 carbon chain with a double bond between carbons 2 and 3. The substituents on the alkene are on opposite sides of the alkene. This reacts with B r 2 to give the intermediate ion.

Answer:

Which atom is oxidized in the reaction of benzhydrol with bleach?

Explanation:

n this experiment, students will perform a simple oxidation reaction of a secondary

alcohol. Recall that Oxidation Is a Loss of electrons while Reduction Is a Gain of electrons (OIL

RIG). In order to apply this mnemonic, you must know the oxidation states of each atom within

the compound, with particular interest on carbon. Carbon can carry oxidation states ranging

from -4 to +4. A few examples are shown in Figure 1 below. It is also common for carbon to

carry an oxidation state of -3, -1, +1, and +3.

Figure 1. Examples of carbon’s oxidation levels.

You may have noticed that all of the compounds in Figure 1 are neutral and carbon has

zero formal charge in each example. The concept of oxidation state and formal charge are

similar with one important difference in the calculation. Both are calculated by taking the

difference between the valence electrons (from the periodic table) and the number of electrons

belonging to that atom within the molecule. For a given atom, the valence electrons will never

change but the electrons ‘belonging’ the atom in the molecule will vary depending on number of

lone pairs and attachments to more or less electronegative atoms. The important difference in

the calculation of oxidation states and formal charge is based on the following assignment of

bonding electrons (Figure 2). This is how the highlighted carbon in ethanol can have an

oxidation state of -1 but a formal charge of zero.

- Oxidation states assign bonding electrons to the more electronegative atom in a bond,

except when the two atoms are the same and the bonding electrons are split equally.

Answer:

so the reaction would probably would be a chemical reaction

"When benzophenone reduces to diphenylmethanol, leftover products include the CH2OH and NaBH3 species. The energetic CH2OH and NaBH3 quickly bond to give (CH2OH)H3B-Na+. This complex is the main second product of benzophenone reduction."

Reactant Ratios

"In life, four benzophenone molecules react with each BH4 complex. Since four benzophenone molecules each attract a hydrogen atom from the “BH4” hydrogen donor, four “CH2OH”s bond with each boron (B) atom. Realistically, the secondary product is (CH2OH)4B-Na+ and four diphenylmethanol molecules. Focusing on one benzophenone molecule at a time is helpful for explaining and understanding reaction steps."

The characteristics of electromagnetic waves  are that they  travel in straight lines and can bounce off surfaces,travel through space at  speed of light,can bend around objects,move by interaction between electric field and magnetic field.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Hello!

In this case, these three equations show how the molecule behaves in terms aqueous and solid species; thus, we first write balanced conventional equation:

[tex]Ca I_2 (aq) + K_2 C_2 O_4 (aq)\rightarrow CaC_2O_4(s)+2KI(aq)[/tex]

Whereas the solid product is CaC₂O₄ based off its low solubility. Next, we ionize the aqueous species to obtain the total ionic equation:

[tex]Ca^{2+} +2I^- + 2K^+ +(C_2 O_4)^{2-} \rightarrow CaC_2O_4(s)+2I^- + 2K^+[/tex]

Finally, we cancel out potassium and iodide ions as they are the spectator ions due to their presence at both reactants and products in order to obtain the net ionic equation:

[tex]Ca^{2+} (aq) +(C_2 O_4)^{2-}(aq) \rightarrow CaC_2O_4(s)[/tex]

tin nitrite Formula:Sn(NO2)2

The formula for tin (II) nitrite Sn(NO2)2.

Two atoms together chemically form a molecule. The chemical formula for a molecular compound's molecular formula lists the variety of atoms that make up the molecule.

A subscript under oxygen in CO2, for instance, indicates that there are two oxygen atoms present, but a subscript under carbon indicates that there is just one carbon atom present.

A nitronium salt is produced when tin(IV) nitrate and trifluoroacetic acid anhydride combine. Trifluoroacetic acid produces a similar molecule when it is solvated with it.

The number of each atom contained in a given molecule is indicated by the molecule's molecular formula. In essence, it is a list of the elements that are present in a molecule and how many of each there are.

Therefore, The formula for tin (II) nitrite Sn(NO2)2.

Explanation:

1) the formula of the energy is:

E=cm*Δt, where E - the value of the energy (5480 J.), c - the specific heat capacity (4200 J/(kg*C)), Δt - the difference between initial temperature and the final one (it is unknown);

2) if to perform the substitution of the values 'E', 'm' and 'c' into the formula above, then

5480=4200*0.65*Δt;

3) to calculate Δt:

Δt=5480/4200/0.65≈2 (°C).

note: the initial temperature is higher than the final.

The reaction that takes place is:

We convert the given reactant masses to moles, using their respective molar masses:

0.83 moles of ethane would react completely with (0.83*7/2) 2.9 moles of O₂. There are more O₂ moles than that, so O₂ is the reactant in excess and ethane is the limiting reactant.

We calculate the produced moles of CO₂ using the moles of the limiting reactant:

Finally we convert CO₂ moles to grams, using its molar mass:

The destruction of ozone is a non-elementary reaction. This means that it does not take place in a single reactive encounter. The reaction rather takes place is a sequence of steps called the reaction mechanism.

We can see that in the overall reaction, ozone is reduced to ordinary oxygen thus the ozone layer is depleted by this reaction. It is a two step reaction as shown.

Both steps (1) and (2) are bimolecular. The equation of the net reaction is shown in the image attached.

In this case, we can do this by thinking a little.

Both ways use a grignard reagent, the difference between both ways is that one use an electrophile ketone with a low molecular mass, and the other has a high molecular mass.

The grignard reagent is commonly used to reduce carbonyle groups to alcohols. In the first step, a complex with the reagent is formed in the carbonile, and in the second step, the oxygen atom is hidrated in acid or basic medium and form the respective alcohol.

For the first way, we will use a high molecular mass ketone. In this case the 2-pentanone reacting with CH₃MgBr as a grignard reagent.

For the second way, we will use a low molecular mass ketone, in this case Acetone, reacting with CH₃CH₂CH₂MgBr. Both of them, will give the same product of 2 methyl-2-pentanol. See picture below for that

Everything in the universe that we can detect is either matter or energy.

Everything in the universe that we can detect is either matter or energy.

Energy exists in the capacity of a physical system to do work. The common symbol for energy exists in the uppercase letter E. The standard unit stands for the joule, symbolized by J. One joule (1 J) exists as the energy resulting from the equivalent of one newton (1 N) of force operating over one meter (1 m) of displacement.

A matter is referred as a substance having a certain mass and  can take up a certain volume in the space. For example pen, pencil, toothbrush, water, milk are matters as well as car, bus, bicycle is also a matter. So matter is considered as a living thing and a non-living thing.

Energy, is the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms.
