Answer:

At equilibrium, the rate of the forward, and the reverse reactions are equal.

Explanation:

In an equilibrium chemical reaction, the rate of forward reaction, is equal to the rate of reverse reaction. Note that the reactions does not cease at equilibrium, but rather, the reactants are converted to product, at the same rate at which the product is also being converted into the reactants in the reaction. When chemical equilibrium is reached, a careful calculation of the value of equilibrium constant is approximately equal to 1.

NB: If the value of equilibrium constant is far far greater than 1, then the reaction will favors more of the forward reaction, and if far far less than 1, the reaction will favor more of the reverse reaction.

A chemical reaction's equilibrium constant is the reaction quotient at chemical equilibrium, the steady state reached by a dynamic chemical system after enough time has passed that its composition shows no detectable tendency to change.

To calculate the equilibrium constant (Kc) for the reaction

2 NO2(g) <=> N2O4(g),

follow these steps:

1. Convert the mass of NO2 and N2O4 to moles using their molar masses:
  Molar mass of NO2 = 46.01 g/mol
  Moles of NO2 = 10.0 g / 46.01 g/mol = 0.2172 mol

  Molar mass of N2O4 = 92.02 g/mol
  Moles of N2O4 = 0.55 g / 92.02 g/mol = 0.005978 mol

2. Calculate the concentrations of NO2 and N2O4 at equilibrium by dividing the moles by the volume of the vessel (7.5 L):
  [NO2] = 0.2172 mol / 7.5 L = 0.02896 M
  [N2O4] = 0.005978 mol / 7.5 L = 0.0007971 M

3. Write the expression for the equilibrium constant (Kc) for the given reaction:
  Kc = [N2O4] / [NO2]^2

4. Substitute the concentrations of NO2 and N2O4 at equilibrium into the Kc expression:
  Kc = (0.0007971 M) / (0.02896 M)^2

5. Calculate the value of the equilibrium constant:
  Kc = 0.0007971 / 0.0008390 = 0.950

The value of the equilibrium constant for this reaction is approximately 0.950.

The correct answer to the multiple choice question is that treasury stock decreases stockholders' equity and has a normal debit balance.

Treasury stock is a term used to refer to shares of a company's stock that the company itself has repurchased. It is not considered an investment, as the company is buying back its own shares rather than investing in another company. When a company repurchases its own shares, it decreases the number of outstanding shares and therefore decreases stockholders' equity.

As a result, the correct answer to the multiple choice question is that treasury stock decreases stockholders' equity and has a normal debit balance. This means that when treasury stock is recorded, it is recorded as a reduction to stockholders' equity, and the accounting entry has a debit balance. Overall, treasury stock can have a significant impact on a company's financial statements and should be carefully managed and monitored.

The compound that acts as an antacid in small doses but as a laxative in larger doses is Mg(OH)₂, also known as magnesium hydroxide.

When taken in small amounts, it neutralizes excess stomach acid and relieves symptoms of heartburn and indigestion. However, when taken in larger doses, it can have a laxative effect by drawing water into the intestines and increasing bowel movements. This is why magnesium hydroxide is commonly found in over-the-counter laxatives and stool softeners.

It's important to follow recommended dosages when taking antacids and laxatives to avoid any adverse effects. In addition, prolonged use of magnesium hydroxide can lead to a buildup of magnesium in the body, which can cause diarrhea, nausea, and other digestive issues.

Explanation:

Rain is produced by two natural processes, i.e., evaporation and condensation. The water from water bodies evaporates into the air and gets condensed in the form of tiny droplets. Enormous droplets of water appear in the form of clouds. When the droplets become big and heavy, they fall down in the form of rain.

Through a procedure known as polymerization, monomers are joined to produce polymers.

the process of polymerization involves the joining of monomers, or small organic molecules, to create polymers, which are larger molecules that resemble long chains. Condensation and addition polymerization are the two primary forms of polymerization.

The method of addition polymerization involves joining together monomers with double or triple bonds to create polymers without losing any atoms. Plastics such as polyethylene and polypropylene are produced using this method of polymerization.

In the process of condensation polymerization, functional monomers like amines and carboxylic acids are linked together to form polymers by removing a tiny molecule like water. Polyamides, polyesters, and polyurethanes are produced using this form of polymerization.

The pH of the solution of the given acid is 3.099

Let  HX  be the weak acid:

HX ⇌  \(H^{+}\)+ \(X^{-}\)

For which:

\(K_{a}\) = [ \(H^{+}\)][ \(X^{-}\)] / [HX]

If  \(K_{a}\) lies in the range \(10^{-4} - 10^{-10}\)we can assume that the equilibrium concentrations used in the expression are a good enough approximation to the initial concentrations.

Rearranging and taking negative logs of both sides gives:

pH = \(\frac{1}{2} [pK_{a} - loga]\)

a is the concentration of the acid.

\(pK_{a} =-logK_{a}\) = -log (2×\(10^{-6}\)) = 5.69

The correct answer to the question is: A) increase, decrease

The first ionization energies of the elements increase as you go from left to right across a period of the periodic table, and decrease as you go from the bottom to the top of a group in the table.

1. Going from left to right across a period, the atomic number increases, which means there are more protons in the nucleus. This results in a stronger attraction between the positively charged nucleus and the negatively charged electrons. As a result, it becomes harder to remove an electron, requiring more energy, and therefore the first ionization energy increases.

2. Going from the bottom to the top of a group, the atomic size decreases. This is because the number of energy levels or shells decreases, and the electrons are closer to the nucleus. As the distance between the nucleus and the outermost electrons decreases, the attractive force between them increases. Consequently, it becomes easier to remove an electron, requiring less energy, and therefore the first ionization energy decreases.

Therefore, the correct answer to the question is:

A) increase, decrease

The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.

Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.

The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.

The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.
