why can a molecule with the strucure of nbr5 not exist
Answers
The molecule with the structure of NBr5 cannot exist because nitrogen does not have a low enough electronegativity to be the central atom of this molecule. The correct option is (D).
In the given molecule, nitrogen is the central atom and is bonded with three bromine atoms. Nitrogen has five valence electrons, and each bromine has seven valence electrons. To complete the octet of each atom, a total of 32 valence electrons are required.
However, if we try to draw the Lewis structure for this molecule, we find that it is not possible to complete the octets for all six atoms using only valence electrons.
Additionally, nitrogen is more electronegative than bromine, meaning it attracts electrons more strongly. Thus, it is unlikely for nitrogen to be a terminal atom in a molecule with a halogen like bromine. Therefore, nitrogen cannot be the central atom in a molecule with three bromine atoms, and such a molecule cannot exist. Option (D) is the correct answer.

give the formula for a potassium solution that could be mixed with a solution of silver nitrate to form silver chromate (as shown below). be sure to include a phase label with your formula.
Answers
Silver chromate (Ag2CrO4) is a solid precipitate that is created when potassium dichromate and silver nitrate combine. Silver chromate is a substance that is solid, as indicated by the phase label "(s)".
The formation of silver chromate from a potassium solution and a solution of silver nitrate involves a double displacement reaction. The balanced chemical equation for this reaction is:
2KNO₃(aq) + Ag₂CrO₄(aq) → 2AgNO₃(aq) + K₂CrO₄(aq)
In this equation, the phase labels indicate that the compounds are dissolved in an aqueous solution (denoted by "(aq)"). The potassium solution (represented by KNO₃) reacts with silver chromate (Ag₂CrO₄) to yield silver nitrate (AgNO₃) and potassium chromate (K₂CrO₄).
It's important to note that the formation of silver chromate requires an additional step, where silver nitrate is mixed with potassium dichromate (K₂Cr₂O₇) to produce silver chromate. The balanced equation for this step is:
2AgNO₃(aq) + K₂Cr₂O₇(aq) → Ag₂CrO₄(s) + 2KNO₃(aq)
Here, the reaction between silver nitrate and potassium dichromate produces a solid precipitate of silver chromate (Ag₂CrO₄). The phase label "(s)" indicates that silver chromate is a solid compound.

6.A sugar molecule contains carbon, hydrogen, and oxygen atoms. The oxygen atoms tend to steal electrons from the other atoms in the molecule, giving the oxygen atoms negative charges and leaving other parts of the sugar molecule positively charged. The molecules in oil, however, consist only of hydrogen and carbon, which share electrons equally. Oil molecules do not have areas of positive and negative charges. Using this information and what you know about water, explain why sugar mixes with water but oil does not.
Answers
Sugar mixes with water but oil does not, because of the polarity of the molecules.
Water is a polar molecule, meaning it has areas of both positive and negative charges. As a result, it has a strong attraction to other polar molecules, such as sugar. When sugar dissolves in water, the positively and negatively charged areas of the sugar molecule interact with the polar water molecules, allowing the sugar to dissolve.
Oil, on the other hand, is a nonpolar molecule, which means it does not have areas of positive and negative charges. Water is a polar solvent that cannot dissolve nonpolar solutes such as oil because the attractions between the water molecules are stronger than the attractions between the oil molecules.
As a result, oil and water do not mix or dissolve in each other.

Which of the forces of molecular attraction is the weakest? A London dispersion forces B hydrogen bond C single covalent bond D dipole dipole interactions
Answers
Answer: London dispersion forces of molecular attraction is the weakest.
Explanation:
The forces which exist between neighboring atoms, molecules or ions can be force of attraction or force of repulsion. These forces are called intermolecular forces.
When ions with same charge come in contact with each other then force of repulsion is there but when ions with opposite charge comes in contact with each other then force of attraction will be there.
These forces are described as follows.
London dispersion forces: The electrostatic attraction between atoms or molecules causes a temporary induced charge on the respective atoms. These attractive forces are weak in nature and called London dispersion forces.
Hydrogen bond: When a hydrogen atom is attached to electronegative atom like fluorine, nitrogen and oxygen then bonding between these atoms is called a hydrogen bond.
Dipole-dipole interaction: When positive end of one polar molecule gets attracted by the negative end of another polar molecule then force existing between these ends is called dipole-dipole interaction.
Single covalent bond: When an atom is sharing its valence electrons with another atom then it is called a covalent bond.
Thus, we can conclude that London dispersion forces of molecular attraction is the weakest.

calculate e.e. of a mixture containing 5.70 g of (-)-glyceraldehyde and 2.0 g of ( )-glyceraldehyde.
Answers
The enantiomeric excess (e.e.) of the mixture containing 5.70 g of (-)-glyceraldehyde and 2.0 g of (+)-glyceraldehyde is 48%.
To calculate the enantiomeric excess (e.e.) of a mixture, we need to determine the difference in the amounts of the two enantiomers and express it as a percentage of the total amount.
Given;
Mass of (-)-glyceraldehyde = 5.70 g
Mass of (+)-glyceraldehyde = 2.0 g
Calculate the total amount of glyceraldehyde in the mixture.
Total mass of glyceraldehyde = Mass of (-)-glyceraldehyde + Mass of (+)-glyceraldehyde
= 5.70 g + 2.0 g
= 7.70 g
Calculate the individual amounts of each enantiomer as a fraction of the total amount.
Fraction of (-)-glyceraldehyde = Mass of (-)-glyceraldehyde / Total mass of glyceraldehyde
= 5.70 g / 7.70 g
= 0.740
Fraction of (+)-glyceraldehyde = Mass of (+)-glyceraldehyde / Total mass of glyceraldehyde
= 2.0 g / 7.70 g
= 0.260
Calculate the enantiomeric excess (e.e.).
e.e. = (Fraction of (-)-glyceraldehyde - Fraction of (+)-glyceraldehyde) × 100%
= (0.740 - 0.260) × 100%
= 0.480 × 100%
= 48%
Therefore, the enantiomeric excess (e.e.) of the mixture containing 5.70 g of (-)-glyceraldehyde and 2.0 g of (+)-glyceraldehyde is 48%.

what is the symbol for the following ion electronic structure: [ne]3s23p6 with an atomic number of 16?
Answers
The ion with electronic structure [ne]3s23p6 and atomic number 16 is the sulfur (S) ion.
The symbol for this ion depends on its charge. Sulfur has six valence electrons in its outermost shell, and when it gains two electrons, it completes its octet and becomes stable.
This results in the formation of the S2- ion, which has a charge of -2.
The symbol for the S2- ion is written as S2-.
The symbol indicates that the ion has two more electrons than the neutral sulfur atom, which has 16 protons and 16 electrons.
The square bracket notation [ne] in the electronic structure of the neutral sulfur atom indicates that it has the same electron configuration as the noble gas neon (Ne) in its outermost shell.
In summary, the symbol for the sulfur (S) ion with electronic structure [ne]3s23p6 and a charge of -2 is S2-.

The law of conservation of mass states that. “The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another”. According to the law of conservation of mass, the mass of the reactants must be equal to the mass of the products for a low energy thermodynamic process.
I’m pretty sure that when balancing a chemical equation no one is thinking about the conservation of mass. It’s all about counting atoms. When you have the same number of each kind of atom on either side of the arrow, then the equation is balanced. Now, that’s not to dismiss the law of conservation of mass which is verified upon closer inspection of the balanced equation.
eg CH4 + O2 → CO2 + H2O - needs balancing.
you use the idea that each type of atoim is conserved - so looking at this you can see it is not currently correct. On the LHS there are 2 O atoms and on the RHS there are 3 O atoms- the number of atoms must remain unchanged. We dont bother about their mass ( although mass is conserved)’

A solution of hydrated sodium carbonate was titrated with 1.6800 M nitric acid solution. It was found that 30.00 cm³ of the solution required 28.75 cm³ of the nitric acid for a complete reaction. If the solution was prepared by dissolving 138.14 g of the carbonate to make 600.00 cm³ of solution, determine the number of molecules of water of crystallisation in the hydrated sodium carbonate, and write its correct formula.
Answers
To determine the number of molecules of water of crystallization in the hydrated sodium carbonate and write its correct formula, we can use the given information and perform a calculation.
First, let's calculate the number of moles of nitric acid used in the titration:
Volume of nitric acid used = 28.75 cm³
Concentration of nitric acid = 1.6800 M
Number of moles of nitric acid = concentration × volume
= 1.6800 M × 0.02875 L
= 0.04824 moles
Since the reaction between nitric acid and hydrated sodium carbonate is 1:1, the moles of nitric acid used are equal to the moles of hydrated sodium carbonate.
Now, let's calculate the number of moles of hydrated sodium carbonate:
Mass of hydrated sodium carbonate used = 138.14 g
Molar mass of hydrated sodium carbonate = 105.99 g/mol (\(Na_2CO_3\))
Volume of solution prepared = 600.00 cm³ = 0.6 L
Number of moles of hydrated sodium carbonate = mass / molar mass
= 138.14 g / 105.99 g/mol
= 1.302 moles
Since the moles of nitric acid and hydrated sodium carbonate are equal, we can determine the number of water molecules of crystallization in the hydrated sodium carbonate.
The molar ratio between hydrated sodium carbonate and water can be found from the balanced chemical equation. Let's assume the formula of hydrated sodium carbonate is \(Na_2CO_3\) · x\(H_2O.\)
From the balanced equation:
1 mole of\(Na_2CO_3\) · x\(H_2O.\) reacts with x moles of water.
Therefore, in this case:
1.302 moles of \(Na_2CO_3\) · x\(H_2O.\) reacts with x moles of water.
Since the number of moles of water is equal to the number of moles of hydrated sodium carbonate, we can conclude that the correct formula for the hydrated sodium carbonate is \(Na_2CO_3\) ·\(1.302 H_2O.\)
So, the number of water molecules of crystallization in the hydrated sodium carbonate is 1.302.

Answers
Therefore, the volume of the gas at 4.00oc and 108.7kpa is 583 ml.
To solve this problem, we need to use the combined gas law, which relates the volume, pressure, and temperature of a gas. The formula for the combined gas law is:
(P1 x V1) / (T1) = (P2 x V2) / (T2)
Where P1, V1, and T1 are the initial pressure, volume, and temperature, respectively, and P2, V2, and T2 are the final pressure, volume, and temperature, respectively.
We can plug in the given values into the formula and solve for V2:
(P1 x V1) / (T1) = (P2 x V2) / (T2)
(65.3 kpa x 654 ml) / (6.00oc + 273.15) = (108.7 kpa x V2) / (4.00oc + 273.15)
Simplifying the equation, we get:
V2 = (65.3 kpa x 654 ml x (4.00oc + 273.15)) / (6.00oc + 273.15) / (108.7 kpa)

Answers
The oxidation half-reaction involves the conversion of solid tin (Sn) to \(Sn^2^+\) ions, while the reduction half-reaction converts chlorine dioxide gas \((ClO_2)\) to \(ClO^2^-\) ions.
To calculate the cell potential, we need to identify the reduction potential (E°) for each half-reaction. The reduction potential for the Sn2+ half-reaction can be found in a standard reduction potential table, which is +0.15 V.
The oxidation half-reaction needs to be reversed since we have it in the opposite direction, so the E° value becomes -0.15 V. The reduction potential for the \(ClO_2\) half-reaction is not given, so we can assume it to be 0 V.
The cell potential (Ecell) is calculated by subtracting the oxidation potential from the reduction potential: Ecell = E(reduction) - E(oxidation). Therefore, Ecell = (0 V) - (-0.15 V) = +0.15 V. This positive value indicates that the reaction is spontaneous and the electrochemical cell is capable of producing electrical energy.
