why should the concentration fo water be the same inside the cell and in the extracellular flid, at equillibrium

The percent yield of the reaction is approximately 88.71%.

To calculate the percent yield of the reaction, we need to compare the actual yield (the amount of Cl₂ formed) to the theoretical yield (the amount of Cl₂ that would be formed if the reaction proceeded with complete conversion of TiCl₄).

First, we need to determine the molar masses of TiCl₄ and Cl₂. The molar mass of TiCl₄ is calculated as follows:

Ti: 1 atom x 47.87 g/mol = 47.87 g/mol

Cl: 4 atoms x 35.45 g/mol = 141.80 g/mol

Total molar mass of TiCl₄ = 47.87 g/mol + 141.80 g/mol = 189.67 g/mol

Next, we can calculate the number of moles of TiCl₄ and Cl₂ based on the given masses:

Moles of TiCl₄ = 15.70 g / 189.67 g/mol ≈ 0.08274 mol

Moles of Cl₂ = 10.40 g / 70.90 g/mol ≈ 0.14676 mol

From the balanced chemical equation for the reaction:

TiCl₄ + 2O₂ → TiO₂ + 2Cl₂

We can see that the stoichiometric ratio between TiCl₄ and Cl₂ is 1:2. Therefore, according to the balanced equation, the theoretical yield of Cl₂ would be:

Theoretical yield of Cl₂

= 2 (moles of TiCl₄)

= 2 (0.08274 mol)

= 0.16548 mol

Percent yield = (actual yield / theoretical yield) 100

= (0.14676 mol / 0.16548 mol) 100 ≈ 88.71%

To calculate the number of grams of nickel (II) nitrate hexahydrate required, we need to use the formula:

moles = concentration (M) x volume (L)

First, let's convert the volume from milliliters (mL) to liters (L):

25 mL = 25/1000 L = 0.025 L

The molar mass of nickel (II) nitrate hexahydrate can be calculated as follows:

Nickel (Ni) atomic mass = 58.69 g/mol

Nitrogen (N) atomic mass = 14.01 g/mol

Oxygen (O) atomic mass = 16.00 g/mol

Molar mass of nickel (II) nitrate = (1 * Ni) + (2 * N) + (6 * O)

= (1 * 58.69) + (2 * 14.01) + (6 * 16.00)

= 58.69 + 28.02 + 96.00

= 182.71 g/mol

Now, we can calculate the number of moles:

moles = 0.034 M x 0.025 L

= 0.00085 moles

Finally, we can calculate the mass of nickel (II) nitrate hexahydrate:

mass = moles x molar mass

= 0.00085 moles x 182.71 g/mol

≈ 0.155 grams

Therefore, approximately 0.155 grams of nickel (II) nitrate hexahydrate are required to prepare a 25 mL solution with a concentration of 0.034 M.

The free energy required to synthesize ATP in a rat hepatocyte is 24,365.6364 J/mol

To calculate the free energy required to synthesize ATP in a rat hepatocyte, we can use the formula:

ΔG'º = -RTln(Q)

where:

ΔG'º is the standard free energy change,

R is the gas constant (8.314 J/(mol·K)),

T is the temperature in Kelvin,

ln(Q) is the natural logarithm of the mass-action ratio.

Given:

ΔG'º = -30.5 kJ/mol

T = 37°C = 37 + 273.15 = 310.15 K

Q = 5.33 x [tex]10^{(-10)[/tex] M

First, we need to convert ΔG'º from kJ/mol to J/mol:

ΔG'º = -30.5 kJ/mol = -30.5 x [tex]10^3[/tex] J/mol

Next, we can calculate the free energy required to synthesize ATP using the formula:

ΔG = ΔG'º - RTln(Q)

ΔG = [tex](-30.5 * 10^3 J/mol) - (8.314 J/(molK) * 310.15 K) * ln(5.33 x 10^{(-10))[/tex]

≈ -30,500 J/mol - 2576.1911 J × (-21.3364)

≈ -30,500 J/mol + 54,865.6364 J

≈ 24,365.6364 J/mol

Calculating this expression will give us the value of ΔG, which represents the free energy required to synthesize ATP in a rat hepatocyte.

Molecular crystals are held together by the intermolecular forces of dispersion and dipole-dipole forces and by hydrogen bonding. The statement is True.

Molecular crystals are held together by the intermolecular forces of dispersion, dipole-dipole forces, and hydrogen bonding.

Dispersion forces are the weakest intermolecular forces and are present in all molecules. They are caused by the temporary uneven distribution of electrons in a molecule, which creates a temporary dipole.

The temporary dipole in one molecule can induce a dipole in another molecule, resulting in a weak attractive force.

Dipole-dipole forces are stronger than dispersion forces and are present in molecules that have a permanent dipole. The positive end of one dipole is attracted to the negative end of another dipole, resulting in a stronger attractive force.

Hydrogen bonding is the strongest intermolecular force and is present in molecules that contain a hydrogen atom bonded to a highly electronegative atom, such as oxygen, nitrogen, or fluorine.

The hydrogen atom is partially positive, while the electronegative atom is partially negative. This creates a strong attractive force between the hydrogen atom of one molecule and the electronegative atom of another molecule.

The type of intermolecular force that is most important in holding a molecular crystal together depends on the structure of the molecules in the crystal.

For example, a crystal of water is held together by hydrogen bonding, while a crystal of methane is held together by dispersion forces.

The statement on the effect of the addition of CuCl₂(aq) to the cathodic compartment is True.

According to Le Chatelier's principle, if the concentration of a reactant in a reaction at equilibrium is increased, the reaction will shift in the direction that consumes that reactant.

The reaction at the cathode is :

Cu₂ + ( aq ) + 2e- ⇄ Cu(s)

By adding CuCl₂(aq), we increase the concentration of Cu₂+ ions in the cathodic compartment. This would cause the reaction to shift to the right, which means more Cu(s) would be produced and more electrons would be consumed.

Therefore, increasing the concentration of Cu₂+ ions in the cathodic compartment will increase the cell potential or emf.

The molarity of the 30% by mass hydrogen peroxide solution is 9.78 M, the mole fraction of H2O2 is 1.0, and the molar concentration is also 9.78 M.

To calculate the molarity, mole fraction, and molar concentration (molarity) of a 30% by mass hydrogen peroxide (H2O2) solution with a density of 1.11 g/ml, we need to follow these steps:

Step 1: Calculate the molarity (M):

The molarity is defined as the number of moles of solute per liter of solution. We need the molar mass of hydrogen peroxide to calculate the number of moles.

The molar mass of H2O2 = 2(1.01 g/mol) + 2(16.00 g/mol) = 34.02 g/mol

The mass of H2O2 in 100 g of the solution (30% by mass) = 30 g

Number of moles of H2O2 = mass / molar mass = 30 g / 34.02 g/mol = 0.882 mol

The volume of the solution can be calculated using the density:

Volume of solution = mass of solution / density = 100 g / 1.11 g/ml = 90.09 ml = 0.09009 L

Molarity (M) = moles / volume = 0.882 mol / 0.09009 L = 9.78 M

Step 2: Calculate the mole fraction (χ) of H2O2:

The mole fraction is the ratio of the moles of H2O2 to the total moles of all components in the solution.

Mole fraction (χ) = moles of H2O2 / total moles

Total moles = moles of H2O2 = 0.882 mol

Mole fraction (χ) = 0.882 mol / 0.882 mol = 1.0

Step 3: Calculate the molar concentration (molarity):

Molar concentration (molarity) is the number of moles of solute per liter of solution.

Molarity (M) = moles of H2O2 / volume of solution = 0.882 mol / 0.09009 L = 9.78 M

If this atom has one additional neutron but the other subatomic particles remained the same as shown, this slightly different atom would be called an isotope.

An isotope is a variant of an atom that has a different number of neutrons. Because isotopes of the same element have the same number of protons in the nucleus, they all have the same atomic number. However, they can differ in mass number, and therefore in atomic mass. In a neutral atom, the number of protons in the nucleus equals the number of electrons that orbit the nucleus, giving the atom a net electrical charge of zero.

However, the number of neutrons in the nucleus can differ, implying that isotopes of the same element may have different atomic masses.

Answer:

What is this?

Explanation:

Answer:

[tex]\boxed {\boxed {\sf molarity = 0.17 \ M \ C_6H_12O_6}}[/tex]

Explanation:

Molarity is found by dividing the moles of solute by liters of solution.

[tex]molarity = \frac {moles}{liters}[/tex]

We are given grams of a compound and milliliters of solution, so we must make 2 conversions.

1. Gram to Moles

We must use the molar mass. First, use the Periodic Table to find the molar masses of the individual elements.

Next, look at the formula and note the subscripts. This tells us the number of atoms in 1 molecule. We multiply the molar mass of each element by its subscript.

6(12.011)+12(1.008)+6(15.999)=180.156 g/mol

Use this number as a ratio.

[tex]\frac {180.156 \ g\ C_6H_12 O_6}{ 1 \ mol \ C_6H_12O_6}[/tex]

Multiply by the given number of grams.

[tex]78 \ g \ C_6H_12O_6 *\frac {180.156 \ g\ C_6H_12 O_6}{ 1 \ mol \ C_6H_12O_6}[/tex]

Flip the fraction and divide.

[tex]78 \ g \ C_6H_12O_6 *\frac { 1 \ mol \ C_6H_12O_6}{180.156 \ g\ C_6H_12 O_6}[/tex]

[tex]\frac { 78 \ mol \ C_6H_12O_6}{180.156 }= 0.432958102977 \ mol \ C_6H_12O_6[/tex]

2. Milliliters to Liters

There are 1000 milliliters in 1 liter.

[tex]\frac {1 \ L }{ 1000 \ mL}[/tex]

Multiply by 2500 mL.

[tex]2500 \ mL* \frac {1 \ L }{ 1000 \ mL}[/tex]

[tex]2500 * \frac {1 \ L }{ 1000 }= 2.5 \ L[/tex]

3. Calculate Molarity

Finally, divide the moles by the liters.

[tex]molarity = \frac {0.432958102977 \ mol \ C_6H_12O_6}{ 2.5 \ L}[/tex]

[tex]molarity = 0.173183241191 \ mol \ C_6H_12O_6/L[/tex]

The original measurement has 2 significant figures, so our answer must have the same. That is the hundredth place and the 3 tells us to leave the 7.

[tex]molarity \approx 0.17 \ mol \ C_6H_12O_6 /L[/tex]

1 mole per liter is also equal to 1 M.

[tex]molarity = 0.17 \ M \ C_6H_12O_6[/tex]
