CF2Cl2 (Carbon difluoride) has the following Lewis structure:

         F

        / \

C = Cl - Cl

        \ /

         F

1. Number of electron groups on the central atom (Carbon, C): 4 (2 single bonds to Fluorine and 2 double bonds to Chlorine), 2. Number of lone pairs on the central atom (Carbon, C): 0, 3. Electron geometry: tetrahedral, 4. Shape: bent or angular.

What is CF2Cl2 Lewis Structure?

A central carbon atom is joined to two fluorine and two chlorine atoms to form the chemical compound CF2Cl2. We can depict this molecule's bonding using its Lewis structure, which displays the location of its electrons.

1. The actions listed below must be taken in order to ascertain the Lewis structure of CF2Cl2:

Calculate the molecule's valence electron count. The number of valence electrons for each element in the molecule can be added to achieve this. With 4 valence electrons for carbon, 7 for fluorine, and 7 for chlorine, a total of 25 valence electrons are present.

2. Position the atoms in the molecule so that the other atoms are positioned around the core atom (carbon, C).  In this case, we have C surrounded by 2 F and 2 Cl atoms.

3. Where double bonds are required, connect the core atom to the outside atoms using single bonds. Since a double bond consists of two pairs of electrons, the chlorine atoms form double bonds with the central carbon atom since they each have seven valence electrons. Since a single bond consists of one pair of electrons and the fluorine atoms each have seven valence electrons, they can only form single bonds with the center carbon atom.

4. Assign the remaining electrons in lone pairs to the center atom. Since all 25 valence electrons in this situation have been spent in bonding, there are no more electrons to designate as lone pairs.

Tired of studying thermo, you come up with the ideal of becoming rich by manufacturing diamond from graphite. To do this process at 25oC requires increasing the pressure until graphite and diamond are in equilibrium. The following data are available at 25oC:
Dg(25oC, 1 atm) = gdiamond- ggraphite = 2866 [J/mol], rdiamond = 3.51 [g/cm3], and rgraphite = 2.26 [g/cm3].
Estimate the pressure at which these two forms of carbon are in equilibrium at 25oC.
How do you get this answer?????Ans: P = 1,514 [MPa] = 15,143 [bar]

Answers

The pressure is P = 1,514 [MPa] = 15,143 [bar].].

To calculate the pressure at which graphite and diamond are in equilibrium at 25oC, you can use the Gibbs free energy equation. The Gibbs free energy of the reaction at 25oC is given by Dg(25oC, 1 atm) = gdiamond- ggraphite = 2866 [J/mol]. Since diamond and graphite are in equilibrium, the change in Gibbs free energy must be zero.

Therefore, we have Dg(25oC, P) = 0, where P is the pressure at which graphite and diamond are in equilibrium. Substituting the given data in the equation and solving for P gives us P = 1,514 [MPa] = 15,143 [bar].

The nuclear chemical equation that describes this nuclear reaction is 32S + 1n --> 32P + 1H.

In nuclear physics, the transformation of a sulfur-32-nuclide into a phosphorus-32-nuclide is a type of nuclear reaction, also known as beta decay. This reaction occurs when a neutron is absorbed by the sulfur-32 atom, causing it to become unstable and emit a proton.

This results in a phosphorus-32 atom, which is a more stable isotope. The resulting reaction can be described by the nuclear chemical equation: 32S + 1n --> 32P + 1H, where 32S represents the sulfur-32 atom, 1n represents the absorbed neutron, 32P represents the resulting phosphorus-32 atom, and 1H represents the emitted proton.

estimate the number of atoms in your body. (hint: based on what you know about biology and chemistry, what are the most common types of atom in your body? what is the mass of each type of atom? appendix d gives the atomic masses of different elements, measured in atomic mass units; you can find the value of an atomic mass unit, or 1 u, in appendix e.)

Answers

It is difficult to estimate the exact number of atoms in a human body because number can vary greatly depending on a person's size and body composition. However, we can make an estimate based on the average mass of the human body and average atomic masses of the most common elements in the body.

The most common elements in the human body are oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. These elements make up approximately 99% of the total body mass.

Using the average atomic masses of these elements and assuming a body mass of 70 kg, we can estimate the number of atoms as follows:

Oxygen: approximately 25 kg, or 3.5 × 10⁻²⁶ atoms.

Carbon: approximately 18 kg, or 2.5 × 10⁻²⁶ atoms.

Hydrogen: approximately 10 kg, or 1.4 × 10⁻²⁶ atoms.

Nitrogen: approximately 3 kg, or 4.2 × 10⁻²⁵ atoms.

Calcium: approximately 1.5 kg, or 2.1 × 10⁻²⁵  atoms.

Phosphorus: approximately 0.8 kg, or 1.1 × 10⁻²⁵ atoms.

So, the total number of atoms in a 70 kg human body would be approximately 10⁻²⁷  to 10⁻²⁸ atoms.

The exact number of atoms in a human body can vary greatly depending on a number of factors, including age, body composition, and overall health.

1CaCO 3 ---> 1 CaO + 1 CO 2
What is the percent yield of this reaction if 24.8 g of CaCO 3 is heated to
give 13.1 g of CaO?

Answers

The theoretical yield of the reaction can be calculated using the stoichiometric ratios from the balanced chemical equation.

1CaCO3 -> 1CaO + 1CO2

The theoretical yield of CaO is equal to the amount of CaCO3 used in the reaction.

The percent yield can then be calculated as follows:

Percent yield = (actual yield / theoretical yield) x 100

Percent yield = (13.1 g CaO / 24.8 g CaCO3) x 100

Percent yield = 52.9 %

Therefore, the percent yield of the reaction is 52.9%.

The basic chemical formula for cellulose is C6H10O5 write a balanced chemical equation that illustrates and supports your answer above

If Gary weighted out 5 grams of cellulose and then sneezed as he carried the cellulose through the lab,how much carbon dioxide is present in the product of the reaction above?

Answers

Answer:

The danger in igniting the Bunsen burner was that cellulose is a highly flammable organic compound, and its combustion reaction would result in a fire or explosion. The chemical properties and behaviors that support this response include cellulose being a complex carbohydrate made up of long chains of glucose units, which are highly reactive and readily burn in the presence of oxygen and heat.

A balanced chemical equation for the combustion of cellulose is:

C6H10O5 + 6O2 -> 6CO2 + 5H2O

If Gary weighed out 5 grams of cellulose and then sneezed as he carried the cellulose through the lab, the amount of carbon dioxide produced from the reaction would be approximately 30 grams (6 moles x 5 grams/mole = 30 grams). This assumes that all of the cellulose was burned completely in a balanced reaction and that the products were able to escape from the reaction vessel.

A compound is basically a new substance that is produced from two or more different chemical elements that react with each other. In other words, this compound is a single substance that can be broken down into several constituent elements.

When combined or reacted, some of the constituent elements will generally lose their properties and will produce new properties according to the substances produced.

There are two ways to analyze the constituent elements of a compound, namely quantitatively and qualitatively. Quantitative is done to find the ratio of the number of elements in a compound, while qualitative is done to find the elements that make up the compound.

Because this compound is a combination of several elements, the name of the compound and its symbol consist of the names of some of its constituent elements.

When does a chemical bond form? Explain in terms of attractions, repulsions and potential energy.

Answers

Answer:

A chemical bond forms when there is a net attractive force between two or more atoms due to the interaction of their electrons. This attractive force results from the balancing of two opposing forces: electron-electron repulsions and electron-nucleus attractions.

Explanation:

The repulsion between electrons arises from their negatively charged nature, which results in a repulsive force when two electrons are close together. On the other hand, the attraction between electrons and nuclei is due to the positively charged nuclei attracting the negatively charged electrons.

When the attractive force between electrons and nuclei overcomes the repulsive force between electrons, the energy of the system decreases, and a chemical bond is formed. This decrease in energy is reflected in a lower potential energy of the system, indicating that the bond is more stable than the individual atoms.

Therefore, the formation of a chemical bond can be understood as the result of an attractive force between the electrons and nuclei of the atoms, which leads to a decrease in potential energy and a more stable, lower-energy state.

Water is not a suitable solvent for ibuprofen because the hydrophobic benzene ring and alkyl side chains are not soluble in water.

Diethyl ether is the best solvent for ibuprofen because its low polarity and low dielectric constant allow it to dissolve the hydrophobic benzene ring and alkyl side chains. Dichloromethane is also a good solvent for ibuprofen, but its higher polarity may cause some of the ibuprofen molecules to become protonated, which could lead to decreased solubility.

Dichloromethane can also be used as a refrigerant, and is found in some food products as an extraction solvent.
