What is the normal boiling point of a 3.45mol solution of kbr that has density of 1.10gml?(ka for h2o is 0.512°c kg/mole)

Answers

Answer 1

The normal boiling point of the 3.45 mol solution of KBr is 104.7384°C.

The normal boiling point of a 3.45 mol solution of KBr with a density of 1.10 g/mL can be calculated using the formula:

ΔT = Kb * molality

where ΔT is the boiling point elevation, Kb is the molal boiling point elevation constant for water (0.512°C kg/mol), and molality is the number of moles of solute per kilogram of solvent.

First, we need to calculate the mass of the solvent (water) required to dissolve 3.45 mol of KBr. The molar mass of KBr is 119 g/mol, so 3.45 mol of KBr would weigh 409.55 g.

Since the density of the solution is given as 1.10 g/mL, the volume of the solution is:

V = m / ρ = 409.55 g / 1.10 g/mL = 372.32 mL

So, the mass of the water is:

mH2O = V * ρH2O = 372.32 mL * 1 g/mL = 372.32 g

The molality of the solution can be calculated as follows:

molality = moles of solute / mass of solvent (in kg) = 3.45 mol / 0.37232 kg = 9.27 mol/kg

Substituting the values in the formula for boiling point elevation:

ΔT = 0.512°C kg/mol * 9.27 mol/kg = 4.7384°C

The normal boiling point of pure water is 100°C, so the boiling point of the KBr solution would be:

Boiling point = 100°C + ΔT = 100°C + 4.7384°C = 104.7384°C

Potassium (K) and copper (Cu) are both in period 4. They both have _____.

four electron shells
similar properties
the same number of electrons
the same number of protons

Answers

Potassium (K) and copper (Cu) are both in period 4. They both have Four electron shells.

Answer:

Similar properties

Explanation:

Potassium (K) has atomic number 19 which means its electron configuration (pattern of electrons in it's energy levels (electron shells)) is 2·8·8·1 while Copper (Cu) has atomic number 29 which means its electron configuration is 2·8·8·8·3 hence Potassium has 4 electron shells while Copper has 5

Potassium has 19 protons (from its atomic number) while Copper has 29 protons

The number of protons and electrons is usually the same (in an atom) (that's why atoms don't naturally have charges i.e they're usually neutral) so Potassium has about 19 electrons while Copper has about 29 electrons.

So similar properties automatically becomes your answer cuz the rest are wrong.

Topic: Mass Balance. A company sells fishmeal to be used as a protein supplement in certain foods. The process consists of: a. Extraction of fish oil, stage in which a pasta is obtained that has 20% flour and 80% water. b. Drying of pasta in a rotary drum, which produces fishmeal with 40% humidity. How much pasta must be input to the process to produce 1000 kg ?

Answers

To produce 1000 kg of fishmeal (M = 1000 kg), you would need 3000 kg of pasta. To determine the amount of pasta required to produce 1000 kg of fishmeal, we need to consider the mass balance of the process. Let's break down the steps involved:

A. Extraction of fish oil:

The pasta obtained from the extraction stage contains 20% flour and 80% water. To calculate the amount of pasta, we need to determine the mass of flour and water in the pasta. Let's assume the total mass of the pasta is P kg.

Mass of flour = 20% of P = 0.2P kg

Mass of water = 80% of P = 0.8P kg

b. Drying of pasta:

During the drying stage, the pasta is dried in a rotary drum, resulting in fishmeal with 40% humidity. This means that the final fishmeal will contain 60% dry matter.

Let's assume the mass of the dried fishmeal is M kg.

Mass of dry matter = 60% of M = 0.6M kg

Since the dry matter in the fishmeal comes from the flour in the pasta, we can equate the mass of dry matter to the mass of flour:

0.6M kg = 0.2P kg

To produce 1000 kg of fishmeal, we want to find the corresponding value of P:

0.6M = 0.2P

P = (0.6M) / 0.2

P = 3M

Therefore, to produce 1000 kg of fishmeal (M = 1000 kg), you would need 3000 kg of pasta.

c) 2.0 x 10-5 m
d) 4.5 x 10-5 m

Answers

The solubility of barium carbonate, BaCo₃ is 4.5 x 10⁻⁵ M.

To find the solubility, the given values are,

Ksp = 2.0·10⁻⁹.

Here, s(BaCO₃) = ?M.

What is Solubility?

In chemistry, Solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent.

Formula for solubility is,

                           Ksp = [A^+]^a [B^-]^b

Ksp = solubility product constant

A^+ = cation in an aqueous solution

B^- = anion in an aqueous solution

a, b = relative concentrations of a and b

The Chemical reaction of Barium carbonate is :

BaCO₃(s) → Ba²⁺(aq) + CO₃²⁻(aq).

s(BaCO₃) = s(Ba²⁺) =s(CO₃²⁻) = x.

Ksp = s(Ba²⁺) · s(CO₃²⁻).

Ksp = x · x.

2.0·10⁻⁹ = x².

x = √2.0·10⁻⁹

  = 4.47x10⁻⁵ M.

So, The solubility of Barium carbonate is 4.5x10⁻⁵ M.

Hence, Option D is the correct answer.

CuO(s) + H₂(g) → Cu(s) + H₂O(l) Cu₂O(s) + H₂(g) → 2Cu(s) + H₂O(l)​

Answers

The reaction of cuprous oxide gives 2 moles of copper metal and cupric oxide gives one mole of pure copper. Then, the mass of Cu₂O is 0.71 g. Then the mass percent of the  Cu₂O in the mixture is 47.3 %.

What is mass percent ?

The mass percent of a compound in a mixture is the ratio of its mass to the total mass of the mixture multiplied by 100. It measures how many grams of the compound is present in 100 g of the mixture.

Given that total mass of mixture  = 1.5 g

let x g be the mass of Cu₂O and 1.5 -x be the mass of CuO.

According to law of mass conservation, the number of moles of copper in the reactant mixture is equal to its number of moles in the product side.

Molar mass of Cu₂O = 143 g/mol

molar mass of CuO = 79.5g

mass of Cu = 63.5 g

Then,

2 × 2x/143 + 1.5 -x/79.5 = 1.2244 g/63.5

159 x + 214.5 -143 x = 0.0192

x = 0.71 g

Then mass percent of Cu₂O = 0.71 g/1.5 g × 100 = 47.3 %.

Therefore, the mass percent of Cu₂O in the mixture is Cu₂O.

Brian Gold heated 4.996 g of sodium carbonate/sodium bicarbonate mixture to a constant mass of 4.842 g, Determine the % weight of sodium carbonate in the original mixture.

Answers

4.996 g of a sodium carbonate/sodium bicarbonate combination were cooked by Brian Gold to a constant mass of 4.842 g, In the original mixture, sodium carbonate made up roughly 3.08% of the weight.

To determine the weight percent of sodium carbonate in the original mixture, we need to calculate the mass of sodium carbonate and divide it by the initial mass of the mixture, then multiply by 100%.

Given:

Mass of the mixture before heating = 4.996 g

Mass of the mixture after heating to constant mass = 4.842 g

Let's assume the mass of sodium carbonate in the mixture is x grams.

The mass of sodium bicarbonate in the mixture can be calculated as the difference between the initial mass and the mass of sodium carbonate:

Mass of sodium bicarbonate = (4.996 g - x g)

Since sodium carbonate contains one sodium atom, one carbon atom, and three oxygen atoms, its molar mass is:

Na₂CO₃ = (2 x 22.99 g/mol) + 12.01 g/mol + (3 x 16.00 g/mol) = 105.99 g/mol

The molar mass of sodium bicarbonate (NaHCO₃) is:

Na₂CO3 = (2 x 22.99 g/mol) + 12.01 g/mol + (3 x 16.00 g/mol) = 105.99 g/mol

Using the law of conservation of mass, we can set up the equation:

(x g) + (4.996 g - x g) = 4.842 g

Simplifying the equation:

4.996 g = 4.842 g + x g - x g

0.154 g = x g

         

Now we can calculate the weight percent of sodium carbonate in the original mixture:

\(\% \text{weight of sodium carbonate} = \left( \frac{\text{mass of sodium carbonate}}{\text{initial mass of mixture}} \right) \times 100\%\)

\(\% \text{weight of sodium carbonate} = \left( \frac{0.154 \, \text{g}}{4.996 \, \text{g}} \right) \times 100\%\)

% weight of sodium carbonate ≈ 3.08%

Therefore, the approximate weight percent of sodium carbonate in the original mixture is 3.08%.

Answers

Cis- and trans-2-butene can both be hydrogenated to butane; thus their energies can be compared. the trans isomer releases less energy upon hydrogenation therefore cis-2-butene higher in energy.

What is hydrogenation?

The process of addition of hydrogen atom to another compound in the presence of catalyst such as nickel, cobalt etc. is termed as hydrogenation process.

Why trans has lesser energy of hydrogenation?

As in trans- isomer, similar atoms or group of atoms are on opposite side. Due to which there is less repulsion between the atoms which results in more stability of trans isomer. On the other hand in cis- isomer, similar atoms or group of atoms are on same side, due to which there is more repulsion between the atoms which results in less stability of cis-isomer.

Due to more stability of trans- isomer less energy is released to add hydrogen to the trans butene as compared to cis butene for the formation of butane.

Thus we concluded that the trans isomer releases less energy than cis isomer in hydrogenation process.

The Equilibrium would shift to produce more NO

The reaction is;

When a reaction is at equilibrium then the forward reaction rate will be equivalent to the reverse reaction rate. Additionally, the concentration of the reactants and products are the same.

Additional reactants favor the formation of more products while additional products favor the formation of more reactants.

For example, when more oxygen is added then more Nitrogen (II) oxide will be formed.

Oxygen is a reactant and when increased it favors forward reaction which leads to the formation of more NO which is the product.

What is Equilibrium reaction?

Chemical equilibrium is the condition in which both reactants and products are present in concentrations that have no further tendency to change with time, resulting in no observable change in the system's properties.

Answers

The molarity of chloride ions in the solution is 0.712 M.

What is molarity?

Molarity (M) is the amount of a substance in a certain volume of solution.

Molarity is also known as the molar concentration of a solution.

For NaCl, we use the following equation to determine the number of moles:

Given mass / Molar mass = number of moles

NaCl is assumed to weigh 1.50 g.

NaCl has a molar mass of 58.5 g/mol.

Using the values in the equation above, we obtain:

NaCl moles are equal to 1.50g/58.5g/mol, or 0.0256mol.

Both sodium and chloride ions are produced in one mole of sodium chloride (NaCl).

0.0256mol = moles of chloride ions

Regarding calcium chloride:

The following equation is used to determine the number of moles for a given molarity:

Molarity of the solution is calculated as follows: moles of solute * 100 / volume of solution (in ML).

(1)

Calcium chloride solution has a molarity of 0.100 M.

50.0 mL is the solution's volume.

Equation 1 is solved with the following values: 0.100M = Moles of CaCl2 * 1000 / 50

CaCl2 moles = 0.100M x 50

Moles of CaCl2 are equal to 0.100M*50/1000, or 0.005 mol.

One mole of calcium chloride yields two moles of chloride ions in addition to one mole of calcium ions.

Chloride ion moles equal (2 x 0.005) = 0.01 moles.

Now, we use equation 1 to determine the molarity of chloride ions in the final solution:

(0.0256 + 0.01) = 0.0356 moles of chloride ions are present in total in the solution.

50.0 mL is the total amount of solution.

Equation 1 is solved for the following values:

Chloride ion molecular weight = 0.0356 * 1000 / 50.0

The solution's molarity is 0.712M.

Consequently, the solution's molarity of chloride ions is 0.712 M.

It is represented by a double arrow (⇌) in chemical equations. In the given equation: H₂O (g) + CO (g) ⇌ H₂(g) + CO₂(g) + 42 KJ

To shift the equilibrium to the right, one or more of the following could occur:

Increasing the concentration of H₂ or CO₂

Decreasing the concentration of H₂O or CO

Increasing the pressure

Removing some of the products (H₂ and CO₂)

Decreasing the temperature

To shift the equilibrium to the left, one or more of the following could occur:

Decreasing the concentration of H₂ or CO₂

Decreasing the pressure

Increasing the temperature

If pressure is increased, the equilibrium will shift in the direction that produces fewer moles of gas. In this case, since there are fewer moles of gas on the right side of the equation (H₂ and CO₂), the equilibrium will shift to the right. If heat is added, the equilibrium will shift in the endothermic direction to absorb the additional heat. In this case, the forward reaction is endothermic (42 KJ on the right side), so the equilibrium will shift to the right to consume the added heat.

If CO is added, the equilibrium will shift to the right to consume the additional CO.The concentration of H₂O and CO₂ will increase, while the concentrations of H₂ and CO will decrease until a new equilibrium is reached.

200 mph. I hope this helps! Have a great day! :)
If the plane was going 600 miles in 3 hours then you would divide 600 by 3 and get 200 miles per hour.
