Answer:

This question is incomplete but the correct option is B

Explanation:

This question is incomplete because of the absence of the "Reference Table S", however the question can still be answered in the absence of the table. The energy described in the question is the ionization energy (energy required to remove the most loosely bound electron in an atom). This question seeks to know the atom (from the options provided) with the least ionization energy.

Ionization energy increases from left to right across the period because it's easier to remove a single electron (valence electron) from the outermost shell than to remove two electrons from the same shell; thus the more the valence electrons (in a shell), the higher the ionization energy. Thus, bromine (Br) and tin (Sn) have high ionization energies because they have more number of electrons in there outermost shell.

Berylium (Be) and strontium (Sr) are both in the group 2 of the periodic table because they both have 2 electrons in there outermost shell. Ionization energy decreases down a group. This is because the farther an electron is from the nucleus, the weaker the force of attraction between the nucleus and the electron. Thus, strontium (Sr) would have a lesser ionization energy between the two and would indeed have the least ionization among the options provided. Hence, the correct option is B

Explanation:

The pH of the solution after adding 28.0 mL of 0.50 M NaOH is approximately 1.85.

The balanced chemical equation for the reaction between HCl and NaOH is:

HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

We can see that the reaction between HCl and NaOH is a neutralization reaction where H+ ions from HCl react with OH- ions from NaOH to form water.

Before the titration, we have a solution of 0.50 M HCl. This means that the concentration of H+ ions in the solution is 0.50 M. When we start adding NaOH, the NaOH reacts with the HCl to form NaCl and water. The H+ ions in the solution are gradually consumed by the NaOH until all of the H+ ions are neutralized. At this point, the solution is neutral with a pH of 7.

To determine the pH after adding 28.0 mL of 0.50 M NaOH, we need to first calculate the moles of HCl present in the solution before the addition of NaOH:

moles of HCl = concentration x volume

moles of HCl = 0.50 M x 0.050 L

moles of HCl = 0.025 mol

We can then calculate the moles of NaOH that have been added to the solution:

moles of NaOH = concentration x volume

moles of NaOH = 0.50 M x 0.028 L

moles of NaOH = 0.014 mol

Since HCl and NaOH react in a 1:1 ratio, we can say that 0.014 mol of H+ ions have been neutralized by the addition of NaOH. This means that the moles of H+ ions remaining in the solution are:

moles of H+ ions remaining = moles of HCl - moles of NaOH

moles of H+ ions remaining = 0.025 mol - 0.014 mol

moles of H+ ions remaining = 0.011 mol

To calculate the pH of the solution, we need to use the equation:

pH = -log[H+]

where [H+] is the concentration of H+ ions in the solution. We can calculate the concentration of H+ ions by dividing the moles of H+ ions remaining by the volume of the solution:

[H+] = moles of H+ ions remaining / volume of solution

[H+] = 0.011 mol / 0.078 L

[H+] = 0.141 M

Finally, we can calculate the pH:

pH = -log[H+]

pH = -log(0.141)

pH = 1.85

Therefore, the pH of the solution after adding 28.0 mL of 0.50 M NaOH is approximately 1.85.

Answer:

5.0 L

Explanation:

The maximum mass of CO₂ produced from the decomposition of 25.5 grams of NaHCO₃ is 6.68 g

2NaHCO₃ -> Na₂CO₃ + H₂O + CO₂

Molar mass of NaHCO₃ = 84 g/mol

Mass of NaHCO₃ from the balanced equation = 2 × 84 = 168 g

Molar mass of CO₂ = 44 g/mol

Mass of CO₂ from the balanced equation = 1 × 44 = 44 g

SUMMARY

From the balanced equation above,

168 g of NaHCO₃ decomposed to produce 44 g of CO₂

From the balanced equation above,

168 g of NaHCO₃ decomposed to produce 44 g of CO₂

Therefore,

25.5 g of NaHCO₃ will decompose to produce = (25.5 × 44) / 168 = 6.68 g of CO₂

If the sample of magnesium used in a lab was contaminated with another metal that doesn't react with hydrochloric acid, then the results obtained in the experiment would be affected.

This is because the data collected during the experiment would reflect the reaction between hydrochloric acid and the contaminated sample instead of pure magnesium. As a result, the following changes in results might have been observed:

1. The mass of the contaminated sample would be higher than the mass of pure magnesium.

2. The rate of reaction between the contaminated sample and hydrochloric acid would be slower than the reaction between pure magnesium and hydrochloric acid.

3. The volume of hydrogen gas collected from the reaction would be lower than the volume of hydrogen gas collected in the reaction between pure magnesium and hydrochloric acid.

Explanation:

Since the process is isentropic, the entropy remains constant. Therefore, we can use the isentropic relation T2 T1   P2 P1   γ 1 γwhere γ is the specific heat ratio, which for methane is approximately 1.3. Since the process is at constant pressure, we can also use the ideal gas law.

P1V1 = P2V2Since the methane is assumed to be incompressible; we can assume that V1 = V2. Combining these equations, we get.T2T1  P1 P2 1.3 1.3   P1 P2 0 154 P1 P2  1, since the volume remains constant. Therefore, we have T2 T1   1This means that the temperature remains constant at 120 K, and the temperature change is 0 K. Therefore, the correct answer is 0 K. Liquid methane is commonly used in various cryogenic applications. The critical temperature of methane is 191 K (or 82 degree C), and thus methane must be maintained below 191 K to keep it in liquid phase. Determine the entropy change of liquid methane as it undergoes a process from 110 K and 1 MPa to 120 K and 5 MPa using tabulated properties and approximating liquid methane as an incompressible substance.

One example of particles that can be drawn closer to occupy a smaller volume is a gas.

In the gaseous state, particles have high kinetic energy and are not strongly attracted to each other. They move freely and randomly, colliding with each other and the container walls.

Since there are minimal intermolecular forces holding them together, gas particles can be compressed or drawn closer together by reducing the volume of the container.

By decreasing the volume of a gas, such as by compressing it in a cylinder or container, the particles have less space to move around. They collide with each other more frequently, increasing the frequency of intermolecular collisions. As a result, the gas particles are drawn closer together, and the overall volume occupied by the gas decreases.
