a net ionic equation to show why solid potassium hydroxide, koH (s), forms a basic solution when it dissolves in water

Equation

KOH (s) [H2O ] →     K+(aq)+OH−(aq)

The Arrhenius theory, the Brnsted-Lowry theory, and the Lewis theory are the three ideas that have contributed to the definitions of acids and bases over time. According to Arrhenius, an acid is a chemical that, when ionised, releases protons (hydrogen ions) into the solution, whereas a base releases hydroxide ions.

According to Brnsted-Lowry, a base is a proton acceptor and an acid is a proton giver. According to Lewis, a base is an electron-pair donor, while an acid is an electron-pair acceptor

KOH satisfies the Arrhenius theory's definition of a base by producing hydroxide ions when ionised. The hydroxide ion is the base component from a Brnsted-Lowry perspective since it can accept a proton to create water. Although it is a little more difficult to understand from a Lewis perspective why this is a base, the oxygen in the hydroxide has three pairs of non-bonding electrons on it. When a proton (acid) is present, it lacks the electrons necessary to create a covalent link, therefore hydroxide donates an electron pair to the proton in order to build a coordinate covalent bond, which produces water. The three theoretical requirements for a base are thus satisfied by the aforementioned net ionic equation.

Explanation:

If 1 half-life is 15 hrs, then 3 half-lives = 3×15 = 45

Therefore, there are 45 hrs in 3 half-lives (b)

The half-life of potassium-42 is 12 hours, from Monday 10 am to Thursday 10 am, a total of 72 hours have passed (3 days).
Since each half-life is 12 hours, there are 6 half-lives in 72 hours. The amount remaining mg at 10 am on Thursday is approximately 2.34 mg.

To calculate the amount of potassium-42 remaining at 10 am on Thursday, we need to determine how many half-lives have passed since Monday. Since the half-life of potassium-42 is 12 hours, from Monday 10 am to Thursday 10 am, a total of 72 hours have passed (3 days).
Since each half-life is 12 hours, there are 6 half-lives in 72 hours.
To find the amount remaining, we can use the formula:
Amount Remaining = Initial Amount * (1/2)^(Number of Half-Lives)
Given that the initial amount is 75.0 mg, we can calculate the amount remaining as follows:
Amount Remaining = 75.0 mg * (1/2)^6
Calculating this, we find that the amount remaining at 10 am on Thursday is approximately 2.34 mg.

The molar solubility of sodium stearate in pure water is 0.00163 mol/L, and the solubility is 0.5 g/L.

To calculate the molar solubility and solubility of sodium stearate (C17H35COONA) in pure water, we need to consider the balanced equation for its dissolution and use the given molecular formula and molar mass.

First, let's write the balanced equation for the dissolution of sodium stearate in water:

C17H35COONA(s) ⇌ C17H35COO−(aq) + Na+(aq)

The molar solubility is defined as the number of moles of solute (sodium stearate) that dissolve per liter of solvent (water). To calculate it, we need to determine the concentration of the sodium stearate ions in the saturated solution.

The molecular formula of sodium stearate (C17H35COONA) indicates that for every molecule that dissolves, one C17H35COO− ion and one Na+ ion are produced. Therefore, the concentration of both ions will be the same in the saturated solution.

To find the molar solubility, we need to calculate the concentration of either the C17H35COO− ion or the Na+ ion. Let's use the C17H35COO− ion.

The molar mass of sodium stearate (C17H35COONA) is 306.44 g/mol.

Now, we can calculate the molar solubility:
Molar solubility = (mass of sodium stearate / molar mass of sodium stearate) / volume of water

Since we are working with pure water, the volume is 1 liter (1000 mL).

To find the solubility in grams per liter (g/L), we multiply the molar solubility by the molar mass of sodium stearate.

Example calculation:
If the mass of sodium stearate dissolved is 0.5 grams, the molar solubility would be:
Molar solubility = (0.5 g / 306.44 g/mol) / 1 L = 0.00163 mol/L
Solubility = 0.00163 mol/L * 306.44 g/mol = 0.5 g/L

The symptoms of intense inflammation and shock occur in some gram-positive bacterial infections due to a group of toxins called superantigens. So the answer is a.

Superantigens are a type of toxin produced by some gram-positive bacteria that can cause an exaggerated immune response in the host. They are different from other bacterial toxins, such as A-B toxins, membrane-disrupting toxins, and lipid A, because they do not specifically target a particular cell type or receptor. Instead, they bind to the MHC-II molecules on antigen-presenting cells and to the T cell receptor, leading to the activation of a large number of T cells. They are able to activate a large number of T cells, which results in the release of a large amount of cytokines, such as interleukin-1, interleukin-2, and tumour necrosis factor. This can cause symptoms such as fever, nausea, vomiting, diarrhoea, and even shock.

The four territories that provide the "bottomless reserve of cheap labor"  were China, India, southeast Asia and parts of Africa. The irony of the exploited labor is that despite being the backbone of the global economy and contributing to the wealth of developed countries.

The four territories that provide the "bottomless reserve of cheap labor" referred to in 187 are likely to be countries or regions in the developing world with large populations and low wages, such as China, India, Southeast Asia, and parts of Africa.

These territories are often exploited by multinational corporations seeking to maximize profits by outsourcing production to these regions where labor is cheap and often unprotected by strong labor laws or unions.

The irony of the exploited labor is that despite being the backbone of the global economy and contributing to the wealth of developed countries, the workers in these regions often live in poverty and face harsh working conditions. They are paid low wages, subjected to long hours, and lack basic benefits such as health insurance and job security. The irony lies in the fact that the workers who are contributing to the wealth and prosperity of others are often themselves unable to enjoy a decent standard of living.

The mass of the silver sample is approximately 39.9 grams.

m_silver = (39.1 × 4.18 × (27.0 - 22.0)) / (0.235 × (27.0 - 100))

m_silver ≈ 39.9g

To determine the mass of the silver sample, we can use the principle of heat transfer and the specific heat capacity equation.

First, we need to calculate the heat lost by the silver and gained by the water using the equation:

Q (heat lost by silver) = Q (heat gained by water)

The formula for calculating heat is:

Q = m × c × ΔT

Where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

The specific heat capacity of water is approximately 4.18 J/g°C, and for silver, it is 0.235 J/g°C.

The initial temperature of the water is 22.0°C, the final temperature is 27.0°C, and the mass of water is 39.1g.

Using the equation, we have:

(m_silver × c_silver × ΔT_silver) = (m_water × c_water × ΔT_water)(m_silver × 0.235 × (27.0 - 100)) = (39.1 × 4.18 × (27.0 - 22.0))

Solving this equation, we find:

m_silver = (39.1 × 4.18 × (27.0 - 22.0)) / (0.235 × (27.0 - 100))

m_silver ≈ 39.9g

Therefore, the mass of the silver sample is approximately 39.9 grams.
