Decreasing saturation water vapor pressure reduces amount of water vapor air can hold, causing a decrease in relative humidity.

Diminishing the immersion water fume pressure brings about a lessening in relative moistness. Relative mugginess is the proportion of how much water fume in the air to the most extreme measure of water fume that the air can hold at a given temperature and tension. The immersion water fume pressure is the greatest measure of water fume that the air can hold at a given temperature.

At the point when the immersion water fume pressure diminishes, the air can hold less water fume, bringing about a decline in how much water fume in the air for a given measure of water fume pressure. This outcomes in a diminishing in relative mugginess, which is the proportion of the genuine water fume strain to the immersion water fume pressure.

The ph of a buffer solution that is 0. 200 m in \(HC_{2} H_{3} O_{2}\) and 0. 100 m in nac2h3o is 4.46.

A buffer solution is a solution that can resist changes in pH even when an acid or base is added to it. Buffers are usually made up of a weak acid and its corresponding salt or a weak base and its corresponding salt. The pH of a buffer solution depends on the concentration of the weak acid and its corresponding salt, as well as the dissociation constant (Ka) of the weak acid.

In this case, the buffer solution is made up of acetic acid (\(HC_{2} H_{3} O_{2}\)) and its corresponding salt, sodium acetate ( \(NaC_{2}H_{3}O_{2}\)). The dissociation of acetic acid can be represented as follows:

\(HC_{2} H_{3} O_{2}\) ⇌ H+ \(C_{2} H_{3} O_{2}^{-}\)

The Ka of acetic acid is 1.8 x 10^-5. The dissociation of sodium acetate can be represented as follows:

\(NaC_{2}H_{3}O_{2}\) ⇌ Na+ + \(HC_{2} H_{3} O_{2}\)

Since sodium acetate is a salt of a weak acid, it will hydrolyze in water to form OH- ions. However, since the concentration of \(NaC_{2}H_{3}O_{2}\) is lower than that of \(HC_{2} H_{3} O_{2}\), the effect of hydrolysis on the pH of the buffer will be negligible.

To calculate the pH of the buffer solution, we can use the Henderson-Hasselbalch equation:

pH = pKa + log([salt]/[acid])

where pKa is the negative logarithm of the dissociation constant (Ka), [salt] is the concentration of the salt (NaC2H3O2), and [acid] is the concentration of the weak acid (\(HC_{2} H_{3} O_{2}\)).

The pKa of acetic acid is 4.76, so:

pH = 4.76 + log([0.100]/[0.200])

pH = 4.76 + log(0.5)

pH = 4.76 + (-0.301)

pH = 4.46_

Therefore, the pH of the buffer solution is 4.46. This means that the buffer is slightly acidic, but it can resist changes in pH when small amounts of acid or base are added to it.

Carbon dioxide undergoes a phase change from a solid (dry ice) to a gas as the temperature is increased at a constant pressure of 101 kPa (approximately 1 atm).

When a solid substance is heated at constant pressure, its temperature increases until it reaches its melting point, at which point it will begin to melt and change from a solid to a liquid. However, some substances, such as carbon dioxide, can also undergo a phase change from a solid to a gas at a certain temperature and pressure, without going through the liquid state. This process is called sublimation.

Carbon dioxide sublimes at a temperature of -78.5 °C (-109.3 °F) at a pressure of 101 kPa (1 atm). This means that when the temperature of carbon dioxide is increased at a constant pressure of 101 kPa, it will change from a solid (dry ice) to a gas without ever becoming a liquid.

1054.67 grams of calcium phosphate are theoretically produced if we start with 3.40 moles of ca(no3)2 and 2.40 moles of li3po4.

To determine the theoretical yield of calcium phosphate (Ca3(PO4)2) produced from 3.40 moles of Ca(NO3)2 and 2.40 moles of Li3PO4, we need to identify the limiting reactant and use stoichiometry.

First, we need to determine the moles of calcium phosphate produced from each reactant. The balanced equation for the reaction is:

3Ca(NO3)2 + 2Li3PO4 → Ca3(PO4)2 + 6LiNO3

From the equation, we can see that the molar ratio between Ca(NO3)2 and Ca3(PO4)2 is 3:1. Therefore, the moles of calcium phosphate produced from Ca(NO3)2 would be 3.40 moles.

Similarly, the molar ratio between Li3PO4 and Ca3(PO4)2 is 2:1. Therefore, the moles of calcium phosphate produced from Li3PO4 would be 2.40/2 = 1.20 moles.

Since the moles of calcium phosphate produced from Ca(NO3)2 (3.40 moles) are higher than those produced from Li3PO4 (1.20 moles), Ca(NO3)2 is the limiting reactant.

To calculate the mass of calcium phosphate, we can use the molar mass of Ca3(PO4)2, which is approximately 310.18 g/mol.

Mass of calcium phosphate = Moles of calcium phosphate × Molar mass

Mass of calcium phosphate = 3.40 moles × 310.18 g/mol

Mass of calcium phosphate ≈ 1054.67 grams

Therefore, theoretically, approximately 1054.67 grams of calcium phosphate would be produced when starting with 3.40 moles of Ca(NO3)2 and 2.40 moles of Li3PO4.

Energy is transferred from one place to another in the form of waves. Waves has two parts i.e. crest and trough.

Explanation:

Energy is transferred from one place to another in the form of waves. Waves has two parts, the highest part of a wave is called the crest, whereas the lowest part is called trough. The distance between the crest and the trough of a wave is known as wave height. When we drop something in the water, waves are produced having high crest and trough means high wave length whereas waves produced on the solid body has low crest and trough means low wave height.

True, an atom in the ground state has a stable valence electron configuration.

Atoms in their ground state have the lowest possible energy level, meaning their valence electrons are in the lowest available energy orbitals. When the valence electrons are in these orbitals, they are at their most stable configuration. This is because electrons prefer to occupy lower energy levels before filling higher energy levels.

In this stable configuration, the atom is less likely to participate in chemical reactions or gain/lose electrons. However, it is important to note that some elements have more than one possible stable valence electron configuration, depending on the energy levels and subshells available for their electrons to occupy.

Explanation:

Determine the mass number for each of the isotopes, which is obtained by adding the number of protons and the number of neutrons. Hence, isotope A has a mass number of 1, isotope B has a mass number of 2, and isotope C has a mass number of 3. To determine the average atomic mass, we multiply the atomic mass of each isotope by its abundance. Hence, we obtain (0.99985 × 1 amu) + (0.00015 × 2 amu) + (0.00 × 3 amu) = 1.00 amu

Taking into account the definition of dilution, the concentration of the diluted solution is 0.063 M.

When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.

Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:

0.197 M× 2.42 mL= Cf× 7.55 mL

Solving:
