Answer:

The answer to part c is the amount of moles of FeBr₃ that will be formed is approximately 0.179 moles

Explanation:

The given chemical reaction is 2Fe + Br₂ → 2FeBr₃

The mass of iron, Fe, in the reaction = 10 g

a) The amount of moles of iron that reacted = The mass of iron in the reaction/(The molar mass of iron)

The atomic mass of iron = 56 amu

Therefore, one mole of iron = 56 grams

The amount of moles of iron that reacted = 10/(56) ≈ 0.179

The amount of moles of iron that reacted ≈ 0.179 moles

b) The amount of moles of bromine that reacted = 3/2 × The amount of moles of iron that reacted

∴ The amount of moles of bromine that reacted = 3/2 × 0.179 ≈ 0.2685

The amount of moles of bromine that reacted ≈ 0.2685 moles

c) The amount of moles of FeBr₃ that will be formed = The amount of moles of iron in the reaction ≈ 0.179 moles

d) The mass of one molecule of FeBr₃ = Mass of 1 atom of iron, Fe + 3 × The mass of 1 atom of bromine, Br

∴ The mass of one mole of FeBr₃ =  56 + 3 × 80 = 296

The mass of one mole of FeBr₃ = The molar mass of FeBr₃ =  296 grams

The mass of FeBr₃ formed = The molar mass of FeBr₃ × The number of moles of FeBr₃ formed

∴ The mass of FeBr₃ formed = 296 × 0.179 ≈ 52.984

The mass of FeBr₃ formed  ≈ 52.984 grams

The alkene addition reaction that occurs specifically in an anti addition is bromination  in CH₂Cl₂ (dichloromethane solvent).Bromine is a liquid that is more easily handled than chlorine gas, many halogen additions are carried out with bromine. Inert solvent such as methylene chloride (CH₂Cl₂)  is typically used for halogen additions because these solvents dissolve both halogens and alkenes.

Attack of the alkene on bromine  gives the bromonium ion, which is attacked at the backside by bromide ion to give the trans-dibromo product. Note that the bromines are delivered to opposite sides of the alkene (“anti” addition). The bromines add to opposite faces of the double bond (“anti addition”). Sometimes the solvent is mentioned in this reaction – a common solvent is CH₂Cl₂ (dichloromethane solvent). CH₂Cl₂ actually has no effect on the reaction, it’s just to distinguish this from the reaction where the solvent is H₂O, in which case a bromohydrin is formed.

Alkenes are hydrocarbons that contain a double carbon bond, whereas alkanes are hydrocarbons that only have single carbon-carbon bonds.

The reason why alkenes are more reactive than alkanes is that the double bond has a very high electron density in comprarison to the single bond of the alkanes. This double bond is made up of one very strong σ bond and a weak π bond.

So generally alkenes react breaking the π bond.

Percentage by mass of chlorate 1 in calcium chlorate 1 is greater than the percentage by mass of chlorate 1 ions in Sodium chlorate.

An oxyanion is a polyatomic ion that contains at least one oxygen atom and one or more other elements, typically nonmetals. Examples of oxyanions include nitrate (NO3-), sulfate (SO42-), and phosphate (PO43-).

The molecular formula for calcium chlorate is Ca(ClO3)2, and the molecular formula for sodium chlorate is NaClO3.

To calculate the percentage by mass of chlorate 1 in calcium chlorate 1, we need to calculate the molar mass of Ca(ClO3)2 and the molar mass of chlorate 1.

Molar mass of Ca(ClO3)2 = 1 mol Ca + 2 mol ClO3

= 40.08 g/mol Ca + 2(35.45 g/mol Cl + 3(16.00 g/mol O))

= 238.06 g/mol

Molar mass of chlorate 1 = 35.45 g/mol Cl + 3(16.00 g/mol O)

= 99.45 g/mol

Now, we can calculate the percentage by mass of chlorate 1 in calcium chlorate 1:

% by mass of chlorate 1 in calcium chlorate 1 = (2 mol ClO3 x 99.45 g/mol) / (1 mol Ca(ClO3)2 x 238.06 g/mol) x 100%

= 83.3%

To calculate the percentage by mass of chlorate 1 in sodium chlorate, we only need to calculate the molar mass of NaClO3 and the molar mass of chlorate 1.

Molar mass of NaClO3 = 22.99 g/mol Na + 35.45 g/mol Cl + 3(16.00 g/mol O)

= 106.99 g/mol

Molar mass of chlorate 1 = 35.45 g/mol Cl + 3(16.00 g/mol O)

= 99.45 g/mol

Now, we can calculate the percentage by mass of chlorate 1 in sodium chlorate:

% by mass of chlorate 1 in sodium chlorate = (1 mol ClO3 x 99.45 g/mol) / (1 mol NaClO3 x 106.99 g/mol) x 100%

= 92.9%

For a reaction to be spontaneous, the change in enthalpy (ΔH) should be negative (exothermic), and the change in entropy (ΔS) should be positive (increase in disorder). The Gibbs free energy (ΔG) can be used to determine the spontaneity, where a negative value of ΔG indicates a spontaneous reaction.

The change in enthalpy (ΔH) and change in entropy (ΔS) values provide important information about the spontaneity of a reaction. For a reaction to be spontaneous, it should have a negative ΔH (exothermic) and a positive ΔS (increase in disorder).

1. If ΔH is negative, it means that the reaction releases energy in the form of heat. This is favorable for a spontaneous reaction because it indicates that the products are more stable than the reactants.

2. If ΔS is positive, it implies an increase in the randomness or disorder of the system. This increase in entropy favors the spontaneity of a reaction since nature tends to move towards higher entropy states.

3. To determine whether a reaction is spontaneous, we can use Gibbs free energy (ΔG). The relationship between ΔH, ΔS, and ΔG is given by the equation: ΔG = ΔH - TΔS, where T represents temperature. If ΔG is negative, the reaction is spontaneous.

The height of the bin is 29.9m.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

The total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area.

The radius of the cylinder, r = 5m

Surface area = 1099 m²

∴ A = 2πrh + 2πr²

  \(h = \frac{A- 2\pi r^2}{2\pi r}\)

  \(h = \frac{1099- 2 (3.141) 5^2}{2 (3.141) 5}\)

Ni²⁺ is the only ion on the list that can exist as both a high-spin and a low-spin octahedral complex. The correct option is B.

An electrostatic model called the crystal field theory (CFT) assumes that the metal-ligand connection is ionic and results only from electrostatic interactions between the metal ion and the ligand. When dealing with anions, ligands are viewed as point charges, and when dealing with neutral molecules, as dipoles.

The crystal field splitting theory predicts that some transition metal ions can exist as either high-spin or low-spin octahedral complexes, depending on the magnitude of the crystal field splitting parameter (Δ) relative to the pairing energy (P).

Of the ions listed, the only one that could exist as either a high-spin or a low-spin octahedral complex is Ni²⁺ (B).

Mn²⁺ (A) is a d⁵ ion and will always form a high-spin octahedral complex due to its large number of unpaired electrons.

Sc³⁺ (C) is a d⁰ ion and does not form octahedral complexes with ligands.

Cu²⁺ (D) is a d⁹ ion and typically forms a low-spin octahedral complex due to the stability of the half-filled d⁹ configuration.

Zn²⁺ (E) is a d¹⁰ ion and does not have any unpaired electrons to undergo spin pairing, so it will always form a low-spin octahedral complex.

Therefore, the correct answer is B) Ni²⁺.

Given a solution of 7. 50 mg of a small protein in 5. 00 mL solution at  7. 650 torr osmotic pressure,  23. 1°C, the molar mass of the protein is 3,686 g/mol

The formula that relates the osmotic pressure and the molar mass is given by:

πv = (w/m) x RT

Where:

π = osmotic pressure (in atm)

v = volume

w = mass

m  = molar mass

R = constant = 0.083 L.atm.mol⁻¹K⁻¹

T = temperature in Kelvin

The given parameters are:

v = 5 mL = 0.005 L

w = 7.5 mg = 0.0075 g

π = 7. 650 torr = 0.01 atm

T = 23.1 + 273 = 296.1 K

Plug these parameters into the formula:

0.01 x 0.005 =  (0.0075/m) x 0.083 x 296.1

m = 3,686 g/mol
