6. El oxígeno gaseoso se calienta a presión constate de 50 °C a 300 K. Se conoce que inicialmente el volumen del sistema era de 1,3 litros. ¿Cuál es el volumen final del sistema?

Answers

Answer:

El volumen final del sistema es 1.2L

Explanation:

La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:

V₁/T₁ = V₂/T₂

Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.

Reemplazando:

V₁ = 1.3L

T₁ = 50°C + 273.15K = 323.15K

V₂ = Incógnita

T₂ = 300K

1.3L/323.15K = V₂/300K

1.2L = V₂

El volumen final del sistema es 1.2L

Answers

Answer:

1 / 2 of her money would be left

Explanation:

Tammy spent 2/5 of her savings on a watch. She then spent 1/6 of the remainder on a bag. What fraction of her money did she have left?

Taking the question bits by bit;

Tammy spent 2/5 of her savings on a watch

Amount Spent = 2/5

Remainder = 1 - 2/5 = 3/5

She then spent 1/6 of the remainder on a bag

Amount Spent = 1/6  *  3/5 = 1/2  *  1/5  = 1 /10

Total amount spent = 2/5 + 1 /10 =   (4 + 1 ) / 10 = 5 / 10 = 1 / 2

Amount left = 1 - 1 /2 = 1 / 2

Answers

The solubility of silver phosphate, Ag₃PO₄, in pure water is approximately 2.6 x 10⁻⁶ mol/L.

Solubility is the maximum amount of solute that can be dissolved in a given amount of solvent at a particular temperature and pressure, usually expressed in units of grams per liter (g/L) or moles per liter (mol/L).

The solubility of Ag₃PO₄ can be calculated using the Ksp expression;

[tex]K_{sp}[/tex] = [Ag⁺]³ [PO₄³⁻]

Let x be the solubility of Ag₃PO₄ in mol/L. Then, at equilibrium, the concentrations of Ag⁺ and PO₄³⁻ ions will be x mol/L. Therefore;

[tex]K_{sp}[/tex] = (x)³ (x)³ = x⁶

Solving for x, we get;

x = [tex](Ksp)^{(1/6)}[/tex] = (2.6 x 10⁻¹⁸[tex])^{1/6}[/tex]

≈ 2.6 x 10⁻⁶ mol/L

Therefore, the solubility is 2.6 x 10⁻⁶ mol/L.

how many unpaired d-electrons are there in the octahedral high-spin cobalt(iii) complex ion, [cof6]3-? (small ligand field splitting)

Answers

There are three unpaired d-electrons in the octahedral high-spin cobalt(iii) complex ion, [CoF6]3- (small ligand field splitting).

In an octahedral high-spin cobalt(iii) complex with small ligand field splitting, the d-electrons occupy the t2g and eg orbitals. As all six ligands are small, they generate a weak ligand field, which results in the energy difference between the t2g and eg orbitals being small, allowing for a high-spin configuration. Cobalt(iii) has five d-electrons, which fill the t2g orbitals first with three electrons, leaving two unpaired electrons in the eg orbitals. Therefore, the complex has three unpaired d-electrons. There are three unpaired d-electrons in [CoF6]3- due to high-spin configuration and weak ligand field splitting, causing a small energy difference between the t2g and eg orbitals.

magine that 500 ml of a 0.100 m solution of hoac(aq) is prepared. what will be the [oac–] at equilibrium in this solution if the acid dissociation constant ka(hoac) = 1.79 x 10–5?

Answers

The equilibrium concentration of OAc- in the 500 mL of 0.100 M solution of HOAc(aq) with a Ka(HOAc) of 1.79 x 10-5 will be approximately 0.00134 M..

To find the [OAc-] at equilibrium, we need to use the Ka expression and an ICE (Initial, Change, Equilibrium) table. The Ka expression for the dissociation of acetic acid (HOAc) is Ka = [H+][OAc-]/[HOAc]. Initially, [HOAc] = 0.100 M, [H+] = 0, and [OAc-] = 0. During the dissociation, [HOAc] will decrease by x, [H+] will increase by x, and [OAc-] will increase by x.

At equilibrium:
Ka = [H+][OAc-]/[HOAc]
1.79 x 10-5 = (x)(x)/(0.100-x)

We can assume that x is small compared to 0.100, so we can simplify the equation to:
1.79 x 10-5 = (x^2)/0.100

Now, solve for x:
x^2 = 1.79 x 10-5 * 0.100
x^2 = 1.79 x 10-6
x ≈ 0.00134

Since x represents the change in [H+] and [OAc-], the equilibrium concentration of OAc- is approximately 0.00134 M.

calculate the boiling point (in degrees c) of a solution made by dissolving 3.71 g of fructose (c6h12o6) in 87 g of water. the kbp of the solvent is 0.512 k/m and the normal boiling point is 373 k.

Answers

Boiling point = Normal boiling point + ΔT = 373 K + (3.71 g/180.16 g/mol) * (0.512 K/m) / (0.087 kg) = 374.12 K.

To calculate the boiling point of the solution, we'll first find the molality (m) of fructose.

Molality is defined as moles of solute per kilogram of solvent.

1. Calculate moles of fructose: (3.71 g) / (180.16 g/mol) = 0.0206 mol
2. Convert grams of water to kilograms: 87 g = 0.087 kg
3. Calculate molality: (0.0206 mol) / (0.087 kg) = 0.237 m

Next, we'll use the molality and the Kbp (0.512 K/m) to find the change in boiling point (ΔT).

4. Calculate ΔT: (0.237 m) * (0.512 K/m) = 0.121 K

Finally, add ΔT to the normal boiling point (373 K).

5. Boiling point = 373 K + 0.121 K = 374.12 K

The boiling point of the solution is 374.12 K, or approximately 101.0°C.

#SPJ11

The boiling point of the solution would be 100.34°C.

To calculate the boiling point elevation, we can use the formula:

ΔTb = Kbp x molality

where ΔTb is the boiling point elevation, Kbp is the boiling point elevation constant of the solvent, and molality is the concentration of the solution in terms of moles of solute per kilogram of solvent.

First, we need to calculate the molality of the solution. We know the mass of fructose (3.71 g) and the mass of water (87 g). We can convert the mass of fructose to moles by dividing by its molar mass:

moles of fructose = 3.71 g / 180.16 g/mol = 0.0206 mol

Then, we can calculate the molality:

molality = moles of fructose / mass of water in kg

molality = 0.0206 mol / 0.087 kg = 0.237 mol/kg

Now we can calculate the boiling point elevation:

ΔTb = Kbp x molality

ΔTb = 0.512 K/m x 0.237 mol/kg = 0.1216 K

Finally, we can calculate the boiling point of the solution:

Boiling point of solution = normal boiling point of solvent + ΔTb

Boiling point of solution = 373 K + 0.1216 K = 373.12 K

We can convert the boiling point to Celsius by subtracting 273.15:

Boiling point of solution = 373.12 K - 273.15 = 100.34°C

Therefore, the boiling point of the solution is 100.34°C.

An acid that partially separates into its ions in water or an aqueous solution is referred to as a weak acid. On the other hand, in water, a strong acid completely dissociates into its ions.

(Cr2O7)2{-} + H2O2 + H{+} = CrO5 + H2O - Chemical Equation Balancer

Answers

The balanced chemical equation represents the stoichiometry of the reaction and ensures that the number of atoms of each element on both sides of the equation is equal, which is necessary for the conservation of mass during a chemical reaction.

The balanced chemical equation for the reaction of dichromate ion [(Cr2O7)2-] with hydrogen peroxide (H2O2) and hydrogen ion (H+) to produce chromate ion (CrO5) and water (H2O) can be written as:

2(Cr2O7)2- + 8H2O2 + 12H+ → 4CrO5 + 16H2O

In this reaction, the dichromate ion is reduced to chromate ion and hydrogen peroxide is oxidized to water. The reaction takes place in an acidic medium, which provides hydrogen ions to protonate the peroxide ion and facilitate the reduction of dichromate ion. The balanced equation shows that two molecules of dichromate ion, eight molecules of hydrogen peroxide, and twelve hydrogen ions are required to produce four molecules of chromate ion and sixteen molecules of water.

Overall, the balanced chemical equation represents the stoichiometry of the reaction and ensures that the number of atoms of each element on both sides of the equation is equal, which is necessary for the conservation of mass during a chemical reaction.

Answer:

Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic
