By donating or sharing one electron with another atom or a molecule such as water.

By exchanging electrons, atoms form chemical bonds. This is determined by how many electrons make up an element's electron clouds. The valence number is equivalent to the number of accessible electrons in the outermost electron cloud. The electrons that are most suitable for forming chemical bonds are called valence electrons. These valence electrons can be shared with another atom to fill open energy levels in a covalent bond. In spite of the fact that this outermost level possesses eight potential electrons, the resulting chemical is an inert noble gas when all eight electrons are present. Atoms that don't have eight electrons in their outermost shells will join forces with other atoms to share the extra pair of electrons until they have eight.

Answer:

its late but this is the answer

Explanation:

The expression relating the concentration of a gas in \(\mu g/m^-^3 (X)\) with the concentration expressed in ppm (Y) is \(Y = (X/MW) * 10^6 / V\)

To derive an expression relating the concentration of a gas in \(\mu g/m^3 (X)\) with the concentration expressed in ppm (Y), we can use the ideal gas law. The ideal gas law states that \(PV = nRT\), where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature. Rearranging the equation, we have \(n = PV/RT\)

To convert the concentration from \(\mu g/m^-^3 (X)\) to moles (n), we divide X by the molecular weight (MW) of the gas. Thus, \(n = X/MW\)

Combining the two equations, we have \(X/MW = PV/RT\)

Since the concentration expressed in ppm (Y) is the same as the number of moles per million parts of air, we can write \(Y = n * 10^6 / V\)

Substituting \(n = X/MW\), we get \(Y = (X/MW) * 10^6 / V\)

Therefore, the expression relating the concentration of a gas in \(\mu g/m^3 (X)\) with the concentration expressed in ppm (Y) is:

\(Y = (X/MW) * 10^6 / V\)

Only certain wavelengths of light will be absorbed since an atom can only hold a certain amount of energy.

The visible zone contains the transitions from 1 to 2 (i.e., 1 to 2, 3 to 2, 4 to 2, 5 to 2, etc.). This explains why only particular wavelengths of light are emitted by and absorbed by hydrogen. The electrons can only be in these specific orbitals, which explains why. The most stable atom's ground state was represented by the orbit nearest to its nucleus, while the orbits farther away denoted higher-energy excited states. Only a few different wavelengths of light were emitted as a result of transitions from an excited state to a lower-energy state.

the positive electrode in an electrochemical cell produces the oxidation half-reaction, which corresponds to an equation that shows the loss of electrons by the species at the electrode.

The positive electrode in an electrochemical cell (also known as the anode) produces the oxidation half-reaction. This half-reaction involves the loss of electrons by the species at the anode and is represented by an equation that shows the oxidation of the species.

For example, in the case of a simple galvanic cell consisting of a zinc electrode and a copper electrode in a solution of their respective ions, the oxidation half-reaction occurs at the zinc electrode:

Zn(s) → Zn²⁺(aq) + 2e-

This half-reaction shows the oxidation of solid zinc (Zn) to form zinc ions (Zn²⁺) in solution and the release of two electrons (2e-) into the external circuit.

Overall, the oxidation half-reaction, which is produced by the positive electrode in an electrochemical cell and correlates to an equation that depicts the species' loss of electrons at the electrode, is produced.

When using the ceteris paribus assumption, all factors affecting demand besides income are held constant. This includes the price of jewelry, the prices of substitutes and complements, tastes and preferences, and expectations about future prices.

For example, if Ryan is studying the effects of income on the demand for jewelry, he would need to hold the price of jewelry constant. If the price of jewelry were to change, it would be difficult to determine whether the change in demand was due to a change in income or a change in the price of jewelry.

Ryan would also need to hold the prices of substitutes and complements constant. Substitutes are goods that can be used in place of jewelry, such as watches and other forms of adornment.

Complements are goods that are used together with jewelry, such as special occasions. If the prices of substitutes or complements were to change, it would also affect the demand for jewelry.

Finally, Ryan would need to hold tastes and preferences constant. Tastes and preferences are the factors that determine what people want to buy. If people's tastes and preferences for jewelry were to change, it would also affect the demand for jewelry.

By holding all of these factors constant, Ryan can isolate the effect of income on the demand for jewelry. This will allow him to make more accurate conclusions about the relationship between income and demand.

B) They will react because X and Y can share two pairs of electrons to become stable

Explanation:

The electron configurations of two elements x and y are given :

X: 1s2 2s2 2p6

Y: 1s2 2s2 2p6 3s2 3p6

The statement that is true for both the elements is that, they both will react as they both can share two pairs of electrons to become stable.

To become stable the outermost shell or p orbital should have 8 electrons, so element X  can gain 2 atoms to become stable.

Element Y can also react as it can also share two atoms to fulfill its 3p orbital and will stable.

Hence, the correct option is "B".

The following formula can be used to determine how many moles of KC1 are present in 1250 mL of 0.75 M KC1: Molarity (M) is equal to the moles of solute per litre of solution.

In this instance, the volume of the solution is 1250 mL, and the molarity of KC1 is 0.75 M. The following formula can be used to determine how many moles of KC1 are present in 1250 mL of 0.75 M KC1: Molarity (M) times the number of litres in the solution equals 0.75 M times (1250 mL/1000 mL/L) or 0.9375 moles of KC1.

Consequently, 0.9375 moles of KC1 are present in 1250 mL of 0.75 M KC1. It is significant to remember that a solution's molarity is a measurement of the amount of a solute present in a given volume of the solution.

Answer:

9.90

Explanation:

Given [H+] = 1.25 x 10^-10 M, we can calculate the pH using the formula:

pH = -log10([H+])

pH = -log10(1.25 x 10^-10)

Using logarithmic properties:

pH = -log10(1.25) - log10(10^-10)

Since log10(10^-10) is equal to -10:

pH = -log10(1.25) - (-10)

pH = -log10(1.25) + 10

Now, evaluating the logarithm using a calculator:

pH = -0.0969 + 10

pH = 9.9031

Therefore, the pH of the solution with [H+] = 1.25 x 10^-10 M is approximately 9.9031. Rounding it to two decimal places, the pH is approximately 9.90.

The half life of the gold isotope can be obtained as 2.5 days

The duration it takes for half of the atoms in a sample of a radioactive substance to decay is known as the half-life. It is a gauge of how quickly a chemical decays radioactively. For describing the decay of isotopes, which are various forms of an element with the same number of protons but differing numbers of neutrons in their atomic nuclei, we utilize the idea of half-life.

By the use of the formula;

N/No = (1/2)^t/t1/2

6.25/100 = (1/2)^10/t1/2

0.0625 =  (1/2)^10/t1/2

Explaination:

The amount of CO2 produced by reaction with 6 kg of bicarbonate with excess hydrochloric acid is 1837.89 L.

This situation's chemical reaction is NaHCO3 + HCl NaCL + H2O + CO2 (g).

M 84 g/mol NaHCO3

44 g/mol for M CO2

As we have 6.00 kg of sodium bicarbonate, 6 kg of sodium carbonate equals 71.43 kg of sodium carbonate.

Because of the chemical reaction's stoichiometry:

71.43 moles of NaHCO3 are equal to 71.43 moles of CO2, and vice versa.

Additionally, since CO2 is an ideal gas, we can apply the formula shown below:

PV=nRT where n = 71.43 mol, R = 0.083 Ltxatm, and

V = (nRT)/P (mol K)

T = 37 °C, K = 310, and atm = 1

This means that V = (71.43x0.083x310)/1 V

CO2 = 1837.89 Lt.
