Answer: 0.75 L

Explanation:

First, calculate the number of moles of AgNO3 in 1.0 L of 0.20 M solution:

\(0.20 mol/L x 1.0 L = 0.20 mol\)

Since the stoichiometric ratio of AgNO3 to CaCl2 is 2:1, we need 0.10 mol of CaCl2 to completely precipitate the Ag+ in the solution.

Next, we can use the molarity and the number of moles of CaCl2 to calculate the volume of 1.5 M CaCl2 needed:

\(0.10 mol / 1.5 mol/L = 0.067 L or 67 mL\)

Explanation:

Although the other statements are true about DNA, it's a spiral helix and can break apart, its main function is that it contains the genetic code for organisms.

The statement  "The mobile phase used during the tlc analysis of dipeptide experiment was silica gel" is false because the mobile phase used during the TLC analysis of the dipeptide experiment could have been silica gel, but this would be unlikely as silica gel is a stationary phase in TLC.

In TLC, the stationary phase is a thin layer of silica gel or other adsorbent material on a flat, inert support, such as a glass plate, and the mobile phase is a solvent that moves through the stationary phase by capillary action. The dipeptide mixture would be applied as a small spot to the stationary phase, and the plate would be developed by allowing the mobile phase to move up the plate, carrying the components of the mixture with it.

Depending on the polarity of the dipeptide and the solvent used as the mobile phase, different adsorbent materials could be used as the stationary phase, including silica gel, alumina, or cellulose.

Citric Acid is the natural acid found in citrus fruits such as oranges lemons and limes, this is what gives the bitter affect

molar mass of PF5 = 125.966 g/mol

125 g PF5 × (1 mol PF5/125.966 g PF5) = 0.992 mol PF5

0.992 mol PF5 × (6.022 × 10^23 molecules PF5);

= 5.97 × 10^23 molecules PF5

Since there 5 fluorine atoms per molecule of PF5,

(5.97.× 10^23 molecules PF5) × (5 atoms F/1 molecule PF5)

= 2.99 × 10^24 atoms F

The freezing point of the solution is -11.8 °C.

The boiling point of the solution is 103.31 °C.

To determine the freezing point of the solution, we can use the equation:

ΔTf = Kf * m

where:

ΔTf is the freezing point depression,

Kf is the cryoscopic constant (for water, Kf = 1.86 °C/m),

m is the molality of the solution (moles of solute per kilogram of solvent).

First, let's calculate the molality (m) of the solution:

Molar mass of ethylene glycol (C2H6O2):

C = 12.01 g/mol

H = 1.01 g/mol (x 6) = 6.06 g/mol

O = 16.00 g/mol (x 2) = 32.00 g/mol

Total molar mass = 12.01 g/mol + 6.06 g/mol + 32.00 g/mol = 50.07 g/mol

Number of moles of ethylene glycol (C2H6O2) = mass / molar mass

Number of moles = 30.8 g / 50.07 g/mol = 0.615 mol

Mass of water = volume x density = 96.6 mL x 1.00 g/mL = 96.6 g

Now, let's calculate the molality:

Molality (m) = moles of solute / mass of solvent (in kg)

Molality = 0.615 mol / 0.0966 kg = 6.36 mol/kg

Now we can calculate the freezing point depression (ΔTf):

ΔTf = Kf * m

ΔTf = 1.86 °C/m * 6.36 mol/kg = 11.8 °C

To find the freezing point of the solution, subtract the freezing point depression from the freezing point of pure water (0 °C):

Freezing point = 0 °C - 11.8 °C = -11.8 °C

To determine the boiling point of the solution, we can use the equation:

ΔTb = Kb * m

where:

ΔTb is the boiling point elevation,

Kb is the ebullioscopic constant (for water, Kb = 0.52 °C/m),

m is the molality of the solution (same value as calculated before: 6.36 mol/kg).

ΔTb = 0.52 °C/m * 6.36 mol/kg = 3.31 °C

To find the boiling point of the solution, add the boiling point elevation to the boiling point of pure water (100 °C):

Boiling point = 100 °C + 3.31 °C = 103.31 °C

The voltage drop across resistor A will be three times greater than the voltage drop across resistor B. Therefore, the correct answer is option C.

Based on Ohm's Law, the current through a resistor is directly proportional to the potential difference across it, and inversely proportional to its resistance. In this circuit, since resistor A has three times the resistance of resistor B, the current through A will be one-third the current through B (option B is incorrect). However, the potential difference across each resistor will depend on the total voltage of the circuit and the individual resistances.

Assuming the voltage across the circuit is constant, the potential difference across A will be three times the potential difference across B (option C is correct). This is because the voltage drop across each resistor is proportional to its resistance, and the voltage drop across resistor A will be three times greater than the voltage drop across resistor B. Therefore, the correct answer is option C.
