Increasing the volume of the solution decreases the concentration of the hydrogen ions which subsequently increases the pH;  hence, increasing volume will increase the pH.

Higher is the concentration of H plus ions, more acidic is the solution and  lower the concentration of H plus ions, the less acidic is the solution. Basic strength of a solution depends on the concentration of OH minus ions.

When an acid and alkali react together, they produce salt and water. Acid + alkali → salt + water . As you know, water is neutral, so the acid alkali come together to neutralize each other to make pH 7.

Answer:

Think of each polar bond in a molecule as a little arrow pointing from positive to negative. This tells us that the bond dipole is a vector quantity. Like any other vector quantity, the direction is a vital aspect of its description. So, the geometry of the molecule determines the direction that the bond dipole vectors point. The polarity of the molecule results from adding up all these individual bond dipoles.

The theoretical yield of carbon dioxide, CO₂ obtained from the reaction is 8.93 g

We'll begin by calculating the mass of citric acid, H₃C₆H₅O₇ that reacted and the mass of carbon dioxide, CO₂ produced from the balanced equation.

H₃C₆H₅O₇ + 3NaHCO₃ —> 3CO₂ + 3H₂O + Na₃C₆H₅O₇

Molar mass of H₃C₆H₅O₇ = (3×1) + (12×6) + (5×1) + (7×16) = 192 g/mol

Mass of H₃C₆H₅O₇ from the balanced equation = 1 × 192 = 192 g

Molar mass of CO₂ = 12 + (2 × 16) = 44 g/mol

Mass of CO₂ from the balanced equation = 3 × 44 = 132 g

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂

Finally, we shall determine the theoretical yield of CO₂. This can be obtained as follow:

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂.

Therefore,

13 g of H₃C₆H₅O₇ will react to produce = (13 × 132) / 192 = 8.93 g of CO₂.

Thus, the theoretical yield of CO₂ is 8.93 g

Answer: 1st. 71.875 g of ethanol could burn in 100 g of oxygen.

2nd. 71.875 g of ethanol could burn in 100 g of oxygen.

Explanation: The balanced equation for the combustion of ethanol (C2H5OH) with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O) is:

C2H5OH + 3O2 → 2CO2 + 3H2O

From the balanced equation, we can see that for every 1 mole of ethanol that burns, 3 moles of oxygen are required. The molar mass of ethanol is 46 g/mol and the molar mass of oxygen is 32 g/mol.

To find the mass of ethanol that could burn in 100 g of oxygen, we can use the following calculation:

mass of ethanol = (mass of oxygen / molar mass of oxygen) x (molar mass of ethanol / molar mass of oxygen)

mass of ethanol = (100 g / 32 g/mol) x (46 g/mol / 32 g/mol) = 71.875 g

Therefore, 71.875 g of ethanol could burn in 100 g of oxygen.

For the second question, the balanced equation for the reaction of magnesium (Mg) with sulfuric acid (H2SO4) to produce magnesium sulfate (MgSO4) and hydrogen (H2) is:

Mg + H2SO4 → MgSO4 + H2

From the balanced equation, we can see that for every 1 mole of magnesium that reacts, 1 mole of hydrogen is produced. The molar mass of magnesium is 24 g/mol and the molar mass of hydrogen is 2 g/mol.

To find the mass of hydrogen that is formed when 2.00 g of magnesium reacts with sulfuric acid, we can use the following calculation:

mass of hydrogen = (mass of magnesium / molar mass of magnesium) x (molar mass of hydrogen / molar mass of magnesium)

mass of hydrogen = (2.00 g / 24 g/mol) x (2 g/mol / 24 g/mol) = 0.08333 g

Therefore, 0.08333 g of hydrogen is formed when 2.00 g of magnesium reacts with sulfuric acid.

A. Buffering, The ability of a solution to minimise significant pH changes after the addition of a basic or acid is referred to as buffering capability.

The right response is A, or buffering capacity. When an acid or base is introduced to a solution, its buffering capacity determines how well it can withstand pH variations. This characteristic plays a crucial role in keeping biological systems' pH levels stable as well as in industrial operations that demand a constant pH. In order to prevent significant variations in pH, buffers react with extra hydrogen ions (H+) or hydroxide ions (OH-). When an amount of additional acid or base is neutralised by a solution with a high buffering capacity, the pH is little affected.

The atoms in the ring portion of the Haworth structure of glucose are oxygen, carbon, and hydrogen.

The Haworth structure is a way to represent the cyclic form of a monosaccharide, such as glucose. In this structure, the atoms are shown in a planar representation, with the oxygen and carbon atoms forming a hexagonal ring and the hydrogen atoms attached to the carbon atoms.

The ring is formed when the hydroxyl group on the fifth carbon atom of the linear structure reacts with the aldehyde group on the first carbon atom, forming a hemiacetal bond. The resulting ring structure is known as a pyranose ring. The ring structure of glucose is important because it affects the reactivity of the molecule and its interactions with other molecules in biological systems.

Based on the information given, the lowest concentration of subunits that will allow the plus end to assemble is 0.3M. This is the critical concentration at one end of the filament.

The critical concentration (CC) is the threshold at which actin subunits will start to polymerize (assemble) or depolymerize (disassemble) in a filament. In your case, the CC at the plus end of the filament is 0.6 μM. For the plus end to assemble, the concentration of actin subunits must be greater than the CC.

Out of the given options:
a. 0.7 μM
b. 100 μM
c. 0.9 μM
d. 0.2 μM
e. 0.44 μM

Options d and e have concentrations below the CC, so they won't allow the plus end to assemble. The lowest concentration that will allow the plus end to assemble is an option a, 0.7 μM, which is just above the CC of 0.6 μM.

So, the correct answer is a. 0.7 μM.

The final temperature of the gas is approximately 40.96 Kelvin.

To determine the final temperature of the gas, we can use the ideal gas law, which states:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature in Kelvin.

First, let's convert the given temperatures to Kelvin. We have:

Initial temperature: -125 degrees Celsius = 148 K (approximate)

Final temperature: Unknown

The initial conditions of the gas are as follows:

Initial pressure (P1) = 1.25 atm

Initial volume (V1) = 1250 mL = 1.25 L (since 1 L = 1000 mL)

Initial temperature (T1) = 148 K

The final conditions of the gas are as follows:

Final pressure (P2) = 50.0 atm

Final volume (V2) = 325 mL = 0.325 L

Final temperature (T2) = Unknown

Using the ideal gas law, we can set up the following equation:

(P1 * V1) / T1 = (P2 * V2) / T2

Substituting the known values:

(1.25 atm * 1.25 L) / 148 K = (50.0 atm * 0.325 L) / T2

Simplifying the equation:

T2 = (50.0 atm * 0.325 L * 148 K) / (1.25 atm * 1.25 L)

T2 = 40.96 K

A buffer containing a higher concentration of sodium acetate than acetic acid would have a pH that is slightly higher than the pKa of acetic acid.

This is because the sodium acetate will react with any added acid, such as H+ ions, to form more acetic acid and sodium ions. This reaction will help to maintain the pH of the solution, but the excess sodium ions will slightly increase the pH of the solution.

In this case, the higher concentration of sodium acetate would shift the equilibrium towards the acetate ion, resulting in a higher pH.

From the mole concept, 14.13 ml of the given solution is needed to administer to a 155.6-lb patient.

The given problem can be solved by following the mole concept. The mole concept is used to calculate the number of moles of solute in a given solution. It is based on Avogadro's number which states that 1 mole of any substance contains 6.022 × 10²³ atoms or molecules.

The recommended dosage of this drug is 0.15 mg per kg of body weight. Therefore, the dosage for a 155.6 lb patient can be calculated as: 155.6 lb = 70.64 kg (rounded off to two decimal places) Dosage for a 70.64 kg patient = 0.15 mg/kg × 70.64 kg= 10.596 mg (rounded off to three decimal places) Now, we know that the given solution contains 0.75 mg of drug per ml of solution. Therefore, the number of milliliters of the given solution needed can be calculated as:

Volume of the solution needed = Dosage of the drug / Concentration of the drug in the solution

Volume of the solution needed = 10.596 mg / (0.75 mg/ml)

Volume of the solution needed = 14.13 ml (rounded off to two decimal places)

Therefore, 14.13 ml of the given solution is needed to administer to a 155.6-lb patient.
