The volume of the tank is approximately 130.75 m³.

To solve this problem, we need to use the concept of air and water vapor mixture. The given data includes the mass of dry air and water vapor, temperature, and total pressure. We can calculate the specific humidity, relative humidity, and volume of the tank using the following steps:

(a) Specific humidity:

The specific humidity (ω) is defined as the ratio of the mass of water vapor (m_w) to the total mass of the air-water vapor mixture (m_t):

ω = m_w / m_t

Given that the mass of water vapor is 0.17 kg and the total mass of the mixture is 15 kg + 0.17 kg = 15.17 kg, we can calculate the specific humidity:

ω = 0.17 kg / 15.17 kg ≈ 0.0112

So, the specific humidity is approximately 0.0112.

(b) Relative humidity:

Relative humidity (RH) is the ratio of the partial pressure of water vapor (P_w) to the saturation vapor pressure of water (P_ws) at the given temperature, multiplied by 100:

RH = (P_w / P_ws) * 100

To find the relative humidity, we need to determine the saturation vapor pressure at 30°C. Using a vapor pressure table or equation, we can find that the saturation vapor pressure at 30°C is approximately 4.246 kPa.

Given that the total pressure is 100 kPa, the partial pressure of water vapor is 0.17 kg / 15.17 kg * 100 kPa = 1.119 kPa.

Now we can calculate the relative humidity:

RH = (1.119 kPa / 4.246 kPa) * 100 ≈ 26.34%

So, the relative humidity is approximately 26.34%.

(c) Volume of the tank:

To find the volume of the tank, we can use the ideal gas law equation:

PV = nRT

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

First, we need to calculate the number of moles of dry air and water vapor in the tank. The number of moles (n) can be obtained using the equation:

n = m / M

Where m is the mass and M is the molar mass.

The molar mass of dry air is approximately 28.97 g/mol, and the molar mass of water vapor is approximately 18.015 g/mol.

For dry air:

n_air = 15 kg / 0.02897 kg/mol ≈ 517.82 mol

For water vapor:

n_water = 0.17 kg / 0.018015 kg/mol ≈ 9.43 mol

Now we can calculate the volume using the ideal gas law:

V = (n_air + n_water) * R * T / P

Given that R is the gas constant (8.314 J/(mol·K)), T is the temperature in Kelvin (30°C + 273.15 = 303.15 K), and P is the total pressure (100 kPa), we can calculate the volume:

V = (517.82 mol + 9.43 Mol) * 8.314 J/(mol·K) * 303.15 K / (100,000 Pa) ≈ 130.75 m³

Explanation:

Small changes in the chemical nature of polysaccharides can make a big difference in how they work in our bodies. Polysaccharides are complex carbohydrates found in things like fiber and medicines. Even tiny changes in their structure can affect how they are digested, how they interact with cells, and their overall impact on our health. Scientists can use these changes to create materials with specific properties or develop new treatments. So, even small tweaks in polysaccharides can have a significant impact on how they function in our bodies.

The relation between V, R, and I can be determined using Ohm's Law and the principles of parallel circuits.

Ohm's Law states that the voltage across a resistor (V) is equal to the current (I) flowing through it multiplied by its resistance (R). This can be expressed as V = I × R

In a parallel circuit, multiple resistors are connected in such a way that the voltage across each resistor is the same. This means that the voltage across all the resistors in parallel will be equal to the total voltage applied to the circuit. Therefore, the voltage (V) in the above equation represents the total voltage applied to the parallel circuit.

Explanation:

SF₆ in the air at a concentration of 1.0 ppb, exerts a partial pressure of 1.0 × 10⁻⁹ atm. At this concentration, 2.3 × 10¹⁰ molecules of SF₆ are contained in 1.0 cm³ of air at 46 °C.

First, we will calculate the partial pressure of SF₆  using the following expression.

\(pSF_6 = P \times \frac{ppb}{10^{9} }\)

where,

\(pSF_6 = P \times \frac{ppb}{10^{9} } = 1 atm \times \frac{1.0 ppb}{10^{9} } = 1.0 \times 10^{-9} atm\)

Then, we will convert 1.0 cm³ to L using the following conversion factors:

\(1.0 cm^{3} \times \frac{1mL}{1cm^{3}} \times \frac{1L}{1000 mL} = 1.0 \times 10^{-3} L\)

Next, we will convert 46 °C to Kelvin using the following expression.

\(K = \° C + 273.15 = 46 + 273.15 = 319 K\)

Afterward, we calculate the moles (n) of sulfur hexafluoride using the ideal gas equation.

\(P \times V = n \times R \times T\\n = \frac{P \times V}{R \times T} = \frac{1.0 \times 10^{-9} atm \times 1.0 \times 10^{-3} L}{(0.082 atm.L/mol.K) \times 319 K} = 3.8 \times 10^{-14} mol\)

Finally, we will convert 3.8 × 10⁻¹⁴ mol to molecules using Avogadro's number.

\(3.8 \times 10^{-14} mol \times \frac{6.02 \times 10^{23} molecules }{mol} = 2.3 \times 10^{10} molecules\)

SF₆ in the air at a concentration of 1.0 ppb, exerts a partial pressure of 1.0 × 10⁻⁹ atm. At this concentration, 2.3 × 10¹⁰ molecules of SF₆ are contained in 1.0 cm³ of air at 46 °C.

Answer: The balanced equation for the complete oxidation reaction that occurs when methane (CH4) burns in air is \(CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O\).

Explanation:

When a substance tends to gain oxygen atom in a chemical reaction and loses hydrogen atom then it is called oxidation reaction.

For example, chemical equation for oxidation of methane is as follows.

\(CH_{4} + O_{2} \rightarrow CO_{2} + H_{2}O\)

Number of atoms present on reactant side are as follows.

Number of atoms present on product side are as follows.

To balance this equation, multiply \(O_{2}\) by 2 on reactant side. Also, multiply \(H_{2}O\) by 2 on product side. Hence, the equation can be rewritten as follows.

\(CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O\)

Now, the number of atoms present on reactant side are as follows.

Number of atoms present on product side are as follows.

Since, the atoms present on both reactant and product side are equal. Therefore, this equation is now balanced.

Thus, we can conclude that balanced equation for the complete oxidation reaction that occurs when methane (CH4) burns in air is \(CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O\).

Answer:

Cyanide and thiamine do not possess specific structural features that enable them to directly catalyze the benzoin condensation reaction. However, they can participate in the catalytic process indirectly by forming complexes with other compounds or enzymes.

1. Cyanide: Cyanide ions (CN-) can act as a nucleophile, attacking the carbonyl group of aldehydes or ketones. This nucleophilic attack forms a cyanohydrin intermediate, which can undergo subsequent reactions to produce various compounds. In the benzoin condensation, cyanide can react with benzaldehyde to form a cyanohydrin, which can then undergo self-condensation to yield the benzoin product.

2. Thiamine: Thiamine, also known as vitamin B1, is not directly involved in catalyzing the benzoin condensation. However, thiamine pyrophosphate (TPP), the active form of thiamine in enzymatic reactions, can play a role. TPP is a cofactor found in enzymes called transketolases. Transketolases facilitate the transfer of two-carbon units between ketose and aldose sugars. While this is different from the benzoin condensation, the presence of TPP in the enzyme active site allows it to facilitate certain carbon-carbon bond-forming reactions.

Explanation:

It's worth noting that these examples describe the indirect involvement of cyanide and thiamine in facilitating reactions related to the benzoin condensation. Other catalysts, such as base compounds (e.g., sodium hydroxide) or other thiamine derivatives, may be used more commonly for direct catalysis of the benzoin condensation.

Both reactions will not take place ordinarily.

The reactivity series is a list of metals in their order of reactivities - usually in ascending or descending order.

Following this order: Li>K> Ba > Sr> Ca > Na > Mg > Al> Mn > Zn > Cr> Fe > Cd >Co > Ni > Sn > Pb> H > Sb> Bi > Cu > Ag > Pd > Hg > Pt > Au

It means that Li is the most reactive and will displace every other metal in reactions while Au is the least reactive and will not be able to displace metals of higher reactivities.

Thus, for the reaction below:

Mn +Ca0 ---> Ca+MnO

Mn is lower in reactivity than Ca and will therefore not be able to displace ca from CaO.
