he pH of the water will determine the toxic effects, if any, of these substances.

Pure water is neutral with the pH of 7. But when water combines with other substance the pH varies as per the acidity of the combining substance.

pH is the measure of acidity of a solution and mathematically it is the negative logarithm of hydrogen ion concentration. Acidic substance have a pH of less than 7 whereas, basic substance have higher pH value.

Water when combines with some acids, its acidity increases. For example acid rain resulting from the reaction of rain water with oxides of nitrogen and Sulphur forming nitric acid and sulphuric acid.

pH of water have a role in the toxic effects of components in water pH and alkalinity of water determines the coagulation of other substances in water.

Hence, the properties of other substance in water is pH dependent and might effect the alkalinity or acidity of water as well the properties of substances in water such as toxicity.

The concentration of H₂SO₃ solution is equal to 0.123 M.

A neutralization reaction is described as a reaction in which an acid and base react to form salt and water. When a strong acid will react with a base then the salt which is formed can be neither acidic nor basic.

When H₂SO₃ (a strong acid) reacts with KOH, the resulting salt is K₂SO₃  and water.

H₂SO₃  +  2KOH   →   K₂SO₃  +   2H₂O

Given, the concentration of KOH = 0.235 M

The volume of the KOH = 65.25 ml = 0.06525 L

The number of moles of KOH, n = M × V = 0.235 × 0.06525 = 0.0153 M

The volume of the  H₂SO₃ = 62.4 ml = 0.0624 L

The number of moles of  H₂SO₃, n = 0.0153/2 = 0.00767 mol

The concentration of H₂SO₃ =0.00767/0.0624 = 0.123 M

Therefore, the molarity of  H₂SO₃ is 0.123 M.

[H₃O⁺] = 8.86 x 10³ M

The dissociation of water :

H₂O(l)⇒H⁺+OH⁻

Hydrogen ions H⁺ bond with H₂O to form H₃O⁺ ions(hydronium ion)

When acid(Hbr acid) is in the presence of water(dissociates), the H⁺ ions bond with water molecules to form hydronium, the reaction :

HBr(aq)+H₂O→H₃O+(aq)+Br−(aq

So Ionization of HBr :

Answer: The size of the orbital is determined by the principal quantum number, so the size of the orbital increases as this value increases. Therefore, an electron in a (n-1) orbital is closer to the nucleus than is an electron in a 'n' orbital.

Explanation:

In an atom, the position and energy of an electron is described by a set of numbers and these sets are called quantum numbers.  

There are four quantum numbers. These are as follows.

1). Principal quantum number - This is denoted by "n" and it determines the size and energy of shell in which electron is present. The value of "n" can be 1, 2, 3, and so on but it can never be equal to zero.

2). Azimuthal quantum number - This is denoted by "l" and it determines the shape of an orbital. For s, p, d and f-shell the values of "n" will be 0, 1, 2, 3. The value of l can vary from -n to +n.

3). Magnetic quantum number - This is denoted by "\(m_{l}\)." and it determines the orientation of an orbital. The value of ml can vary from -l to +l.

4). Spin quantum number -- This is denoted by "\(m_{s}\)" and it determines the spin of an electron. It is independent of the values of n, l and \(m_{l}\).

This means that the size of an orbital is determined by principal quantum number. Lower is the value of 'n' (principal quantum number) more closer will be an electron to the nucleus. Hence, more is the value of 'n' more will be the size of nucleus and vice-versa.

For example, an electron present in a 2s-orbital is closer to the nucleus as compared to the electron present in a 3s-orbital.

Thus, we can conclude that the size of the orbital is determined by the principal quantum number, so the size of the orbital increases as this value increases. Therefore, an electron in a (n-1) orbital is closer to the nucleus than is an electron in a 'n' orbital.

Answer:

d=m/

Explanation:

d is density, m is mass, v is volume

Given: m =10.4g, v=12.2mL

substituting in equation,

d=10.4/ 12.2

d=0.8524g/mL

To learn more about density:

The density of the liquid is 0.852 g/mL.

To calculate the density of the liquid, we need to use the formula:

Density = Mass / Volume

Given that the mass of the liquid is 10.4 g and the volume is 12.2 mL, we can substitute these values into the formula:

Density = 10.4 g / 12.2 mL

Simplifying this expression, we find:

Density = 0.852 g/mL

Density is a physical property of a substance and is defined as the amount of mass per unit volume. In this case, the density tells us that for every milliliter of the liquid, there is 0.852 grams of mass. The units of grams per milliliter (g/mL) indicate that the density is a ratio of mass to volume.It is important to note that the density of a substance can vary with temperature, so this value is only valid under the conditions at which the measurement was made. Additionally, the density can provide valuable information about the identity of a substance, as different substances have different densities.

To answer this question, we need to know the balanced chemical equation for the reaction between iron (III) oxide and another substance that would produce iron.

Assuming the reaction is:

Fe₂O₃ + 3CO → 2Fe + 3CO₂

This equation tells us that one mole of Fe₂O₃ reacts with three moles of CO to produce two moles of Fe. We can use this information to calculate the number of moles of Fe that can be produced from 450 grams of Fe₂O₃.

Convert the mass of Fe₂O₃ to moles in the first step:

Molar mass of Fe₂O₃ = 2 x atomic mass of Fe + 3 x atomic mass of O = 2 x 55.85 + 3 x 16.00 = 159.69 g/mol

Number of moles of Fe₂O₃ = 450 g / 159.69 g/mol = 2.82 mol

According to the balanced chemical equation, 1 mole of Fe₂O₃ produces 2 moles of Fe. Therefore, the number of moles of Fe that can be produced from 2.82 mol of Fe₂O₃ is:

Number of moles of Fe = 2.82 mol x (2 mol Fe / 1 mol Fe₂O₃) = 5.64 mol

Convert the number of moles of Fe to grams in the final step:

Molar mass of Fe = 55.85 g/mol

Mass of Fe produced = 5.64 mol x 55.85 g/mol = 315.89 g

Therefore, if 450 grams of iron (lll) oxide are reacted with carbon monoxide to produce iron, the amount of iron produced would be 315.89 grams.

0.156000 is written as 1.56000 × 10-1 in scientific notation.

An electron has a negative charge.

The charge of an electron is a fundamental property of the particle, and it is denoted by the symbol "e." The magnitude of the charge of an electron is approximately 1.602 × 10^-19 coulombs (C). This value is considered the elementary charge and is used as a reference for other charges. The charge of an electron plays a significant role in determining the behavior and interactions of atoms and molecules. It is opposite in sign to the charge of a proton, which is positive. The electron's charge allows it to interact with other charged particles, such as protons and ions, through electrostatic forces. Electrons are subatomic particles that orbit the nucleus of an atom in specific energy levels or orbitals. They contribute to the overall stability and chemical properties of atoms and participate in chemical bonding and reactions. The movement of electrons between atoms is what enables the formation of chemical bonds and the sharing or transfer of electrons to create ions. In summary, the charge of an electron is negative, and it plays a fundamental role in the structure and behavior of atoms and molecules.

Division by zero is undefined because there is no other number to divide it by.

Explanation:

Unlike 2/2, 2/0 doesn't have anything to divide the 2 by which makes it undefined and impossible to solve.

The division by zero is undefined​, because whatever response we may give, we will then have to concur that the answer times 0 = 1, which is illogical because anything multiplied by zero is zero.

Since any attempt at definition results in a contradiction, the outcome of a division by zero cannot be defined. a=r*b. r*0=a. (1) (1) But because r*0=0 for all r, there is no solution to the equation unless a=0 (1).

Again, mathematicians have left zero divided by zero as an open problem because they are both equally valid and, to be honest, neither of them is consistent with the rest of mathematics.

Mathematically, it is impossible to divide a number by zero, just as in this illustration. Or, at the very least, there isn't currently a means to do that. Numerous attempts have been made to figure out how to divide by zero, as mathematicians are constantly looking for solutions to intriguing mathematical issues.
