The conjugate base of a neutral acid that donates a proton will have a charge of -1.

When a neutral acid donates a proton, it is undergoing a process called deprotonation, meaning it has lost a proton from its molecular structure. In this reaction, the neutral acid becomes an anion (negatively charged ion) and the proton is picked up by the base, which is then referred to as the conjugate base of the acid. The conjugate base will have a charge of -1 because it now has one extra electron relative to the original neutral acid.
To illustrate this reaction, consider acetic acid (CH3COOH) donating a proton to a base. When the acid donates a proton, it becomes an anion, CH3COO-, and the base, which has gained a proton, is the conjugate base and has a charge of -1.
In summary, when a neutral acid donates a proton, the conjugate base will have a charge of -1.

To produce ammonia (NH₃) from thin air, the reactants required are N₂ and H₂. So the correct option is b).

Ammonia is one of the most abundantly produced inorganic chemicals. In 2016, there are a number of large ammonia plants around the world that produced a total of 144 million tons of nitrogen (equivalent to 175 million tons of ammonia). That number will rise to 235 million tonnes of ammonia in 2021. China produced 31.9% of its global production, followed by Russia at 8.7%, India at 7.5% and the United States at 7.1%. More than 80% of the ammonia produced is used as fertilizer for agricultural crops.

Today, most ammonia is produced on a large scale using the Haber process, with capacities of up to 3,300 tons per day. Gases N₂ and H₂ are reacted at a pressure of 200 bar. A typical modern ammonia production plant first converts natural gas, LPG, or petroleum gas into gaseous hydrogen. The process of producing hydrogen from hydrocarbons is known as steam reforming. Hydrogen then combines with nitrogen to produce ammonia by the Haber-Bosch process.

One way to produce green ammonia is to use hydrogen from the electrolysis of water and nitrogen separated from air. These are fed into the Haber Process (aka Haber-Bosch), all of which produce sustainable power.

The volume of the container is approximately 6.03 L if the oxygen gas is at room temperature and pressure.

What is pressure ?

Pressure is a physical quantity that measures the force exerted per unit area. It is a measure of how much force is distributed over a certain area. Pressure is important in many areas of science and engineering, including fluid mechanics, thermodynamics, and materials science.

At standard temperature and pressure (STP), which is commonly defined as a temperature of 0°C (273.15 K) and a pressure of 1 atm (101.3 kPa), the molar volume of any ideal gas is 22.4 L/mol. However, in this problem, we are given the amount of gas in moles and not at STP, so we need to use the ideal gas law to solve for the volume.

The ideal gas law is given by the equation:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant (0.08206 L·atm/(mol·K)), and T is the temperature in Kelvin.

We are given that the container holds 0.25 moles of oxygen gas. The temperature is not specified, but we are told that the gas is at room temperature, which is typically around 20°C (293.15 K). The pressure is also not specified, but we can assume that it is approximately equal to the standard atmospheric pressure of 1 atm.

Plugging in these values into the ideal gas law equation, we get:

V = (nRT)/P

V = (0.25 mol)(0.08206 L·atm/(mol·K))(293.15 K)/1 atm

V = 6.03 L

Therefore, the volume of the container is approximately 6.03 L if the oxygen gas is at room temperature and pressure.

Alkene products are produced in mixes via the elimination process. According to Zaitsev's rule, base-induced elimination results in the primary alkene product being the more strongly substituted double bond.

An chemical process known as a unimolecular elimination (E1) produces a double bond by removing an H-X substituent from an organic molecule. Because the creation of the carbocation intermediate (similar to an SN1 reaction) from simply the X substituent departing on its own is the reaction's rate-limiting step, it is unimolecular in nature:

A two-step process called an E1 elimination reaction uses a carbocation intermediate:

The elimination of the departing group is the mechanism's initial phase. In this instance, the bromine is the departing group.

Gram-negative bacteria appear as pink/red under the microscope after counterstaining with safranin. In conclusion, the appearance of a gram-negative bacteria cell after the addition of the decolorizing agent (ethyl alcohol) in the Gram stain is colorless.

The appearance of a gram-negative bacteria cell after the addition of the decolorizing agent (ethyl alcohol) in the Gram stain is colorless. Gram staining is a common microbiological method that is used to differentiate bacteria into two categories: Gram-positive and Gram-negative. This differentiation is based on differences in the composition of their cell walls. Gram staining is used to identify bacteria and fungi by staining the samples with crystal violet and iodine, then decolorizing with ethanol and counterstaining with safranin. This method helps to determine the presence or absence of a thick layer of peptidoglycan in the cell wall of bacteria. In Gram-negative bacteria, the decolorizing agent, ethyl alcohol, remove the outer membrane, causing the crystal violet stain to be removed from the cell wall, therefore resulting in a colorless appearance. The alcohol also increases the permeability of the thin peptidoglycan layer, which makes the safranin stain visible in the cell wall of the bacteria.

The alkene that is most stabilized through hyperconjugation is 2-methylpropene. The correct option is (C).

Hyperconjugation is a type of resonance that involves the overlapping of an unshared electron pair on an atom, like carbon, with an adjacent sigma bond. In this case, the unshared electron pair on the methyl group of 2-methylpropene provides stabilization to the adjacent sigma bond, making it the most stabilized alkene through hyperconjugation.

The most stabilized alkene through hyperconjugation can be determined by analyzing the degree of substitution. The greater the number of alkyl groups attached to the carbon atoms of the double bond, the greater the degree of substitution and the greater the stability due to hyperconjugation. Hence, the answer to this question would be option C (2-methylpropene.), as it has the greatest degree of substitution and is thus the most stable through hyperconjugation.

Option A (1-butene) has only one methyl group attached to one carbon of the double bond, making it less stable than option C. Option B (2-butene) has two methyl groups attached to the same carbon atom of the double bond, resulting in a similar degree of substitution to option A. Option D (2-methyl-1-pentene) has a lesser degree of substitution than option C because the methyl group is attached to only one carbon atom of the double bond, while in option C, the methyl group is attached to a tertiary carbon atom.

Hence, option C , 2-methylpropene. is the most stabilized alkene through hyperconjugation because of its greater degree of substitution.

The vapor pressure of methanol at 4.2 oC is approximately 1.6 torr.

The Clausius-Clapeyron equation relates the vapor pressure of a substance at two different temperatures and its enthalpy of vaporization. The equation is:

ln(P2/P1) = (-ΔHvap/R)(1/T2 - 1/T1)

where;

We are given the enthalpy of vaporization for dimethyl ether, which is 27.5 kJ/mol. We are also given the vapor pressure of dimethyl ether at 34.6 ⁰C, which is 760 torr.

We want to find the vapor pressure of methanol at 4.2 ⁰C.

Let's choose the vapor pressure of dimethyl ether at 34.6 ⁰C as the first state, and the vapor pressure of methanol at 4.2 ⁰C as the second state. We can convert the temperatures to kelvin by adding 273.15:

T1 = 34.6 + 273.15 = 307.75 K

T2 = 4.2 + 273.15 = 277.35 K

We can plug in the values into the Clausius-Clapeyron equation:

ln(P2/760) = (-27.5×10^3 J/mol)/(8.314 J/(mol·K)) × (1/277.35 K - 1/307.75 K)

Simplifying:

ln(P2/760) = -5.721

P2/760 = e^-5.721

A) To solve this problem, we can use the formula for the ionization constant of water:

Kw = [H3O+][OH-]

At 50 oC, Kw = 5.476 x 10-14. We can assume that [H3O+] and [OH-] are equal since we are dealing with pure water.

Therefore,

[H3O+] = [OH-] = sqrt(Kw) = sqrt(5.476 x 10-14) = 7.40 x 10-8 mol/L

pH = -log[H3O+] = -log(7.40 x 10-8) = 7.13

pOH = -log[OH-] = -log(7.40 x 10-8) = 7.13

To find the values for pure water at 60oC, we can use the new value of Kw at that temperature:

Kw = 9.550 x 10-14

[H3O+] = [OH-] = sqrt(Kw) = sqrt(9.550 x 10-14) = 3.09 x 10-7 mol/L

pH = -log[H3O+] = -log(3.09 x 10-7) = 6.51

pOH = -log[OH-] = -log(3.09 x 10-7) = 6.51

b) i) No, it does not mean that pure water becomes more acidic as the temperature rises.

ii) The correct answer is 2. As the temperature increases, the ionization of water increases and more H3O+ and OH- ions are formed. However, since the concentration of H2O is also decreasing due to the increase in temperature, the increase in ionization does not result in an increase in [H3O+] and pH actually decreases.

n = V × c

0.005 = V × 0.1

V = 0.005 ÷ 0.1

V = 0.05

This reaction will take 0.05 dm³ of H2SO4, or 50 cm³
