Potassium sulfate is added to water. The equation that best represents this process
is:
K₂S(s) → K(s) + 2 S(s)
K₂S(s) K(s) + 2 S(s)
K₂SO4(s) → 2 K (aq) + SO4² (aq)
K₂S(s) 2 K (aq) + S² (aq)
K₂SO4(s) 2 K(s) + SO4(g)
K₂S(s)→2 K (aq) + S² (aq)
K₂SO4(s)→2 K(s) - SO4(g)
K₂SO4(s) 2 K (aq) + SO4²(aq)

Answers

Answer 1

The equation that best represents the addition of potassium sulfate to water is [tex]K_2SO_4(s) -- > 2 K^+ (aq) + SO4^{2-} (aq)[/tex]

Dissolution of potassium sulfate in water

When potassium sulfate is dissolved in water, it dissociates into its cation and anion according to the following equation:

[tex]K_2SO_4(s) -- > 2 K^+ (aq) + SO4^{2-} (aq)[/tex]

The positive ions are 2 moles of potassium ions while the negative ion is a mole of sulfate ion.

Se queman 87,0 g de butano con oxígeno produciéndose dióxido de carbono y agua. Calcular la masa de oxígeno necesaria y la masa de dióxido de carbono y de agua que se desprenderá

Answers

Answer:

312g O₂ son necesarios, se producen 264g CO₂ y 135g H₂O

Explanation:

La combustión de butano para producir CO₂ y H₂O ocurre así:

C₄H₁₀ + 13/2O₂ → 4CO₂ + 5H₂O

Donde 1 mol de butano reacciona con 13 moles de oxígeno para producir 4 moles de dióxido de carbono y 5 moles de agua.

Para resolver este problema debemos convertir la masa de butano a moles y, usando la reacción balanceada, obtener cuánto se necesita de oxígeno y cuánto se produciría de dióxido de carbono y agua:

Moles butano -Masa molar: 58.12g/mol-:

87.0g * (1mol / 58.12g) = 1.50 moles

Moles y masa de oxígeno necesarias para la reacción -Masa molar: 32g/mol-:

1.50 moles C₄H₁₀ * (13/2 moles O₂ / 1 mol C₄H₁₀) = 9.75 moles * (32g/mol) =

312g O₂ son necesarios

Moles y masa de dióxido de carbono producidas -Masa molar: 44.01g/mol-:

1.50 moles C₄H₁₀ * (4 moles CO₂ / 1 mol C₄H₁₀) = 6 moles * (44.01g/mol) =

264g CO₂ se producen

Moles y masa de agua producidas -Masa molar: 18.015g/mol-:

1.50 moles C₄H₁₀ * (5 moles H₂O / 1 mol C₄H₁₀) = 7.5 moles * (18.015g/mol) =

135g H₂O se producen

Answers

Answer:

pH = 11.30

Explanation:

pH is defined as -log [H⁺]

To find [H⁺] from [OH⁻] -Concentration of hydroxide ion-, we must use the equilibrium of water:

H₂O(l) ⇄ H⁺(aq) + OH⁻(aq)

Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]

[H⁺] = 1x10⁻¹⁴ / [OH⁻]

[H⁺] = 1x10⁻¹⁴ / 2x10⁻³M

[H⁺] = 5x10⁻¹²M

pH = -log (5x10⁻¹²M)

pH = 11.30

Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below. What experimental evidence led to the development of this atomic model from the one before it?

Answer:

A few of the positive particles aimed at a gold foil seemed to bounce back.

Explanation:

This model of the atom was proposed by Ernest Rutherford and was called the planetary model of the atom.

This model is based on an experiment using a gold foil on which alpha particles were focused. Most of the alpha particles passed through the foil. Some of the alpha particles were scattered at large angles and a few seemed to bounce back.

This led to the conclusion that the atom has a massive positive core around which electrons move as planets move around the sun.

What would the [OH-] of a solution that has a pOH of 2.7 be?

Answers

Answer:

[OH⁻] = 0.002 M

Explanation:

The definition of pOH is similar to the definition of pH:

pOH = -log[OH⁻]

This means that with a given pOH value, the calculation of [OH⁻] is a matter of algebra:

2.7 = -log[OH⁻]-2.7 = log[OH⁻]

To remove the logarithm we increase 10 by the power of the pOH:

[tex]10^{-2.7}[/tex]=[OH⁻]0.002 M = [OH⁻]

Nitrogen gas is being withdrawn at the rate of 4.5 g/s from a 0.15-m3 cylinder, initially containing the gas at a pressure of 10 bar and 320 K. the cylinder does not conduct heat, nor does its temperature change during the emptying process. What will be the temperature and pressure of the gas in the cylinder after 5 minutes? What will be the rate of change of the gas temperature at this time? Nitrogen can be considered to be an ideal gas with Cp*=30 J/mol.K.

Answers

Answer:

Final temperature = 152.57K,

Pressure = 0.6907 bar.

dT/dt = - 1,151 K/s.

Explanation:

The first thing to do here is to write out the equation for mass balance as given below:

dN/dt = N -------------------------------------------------------------------------------------------(1).

N = P/T, then, substitute the values given in the question into:

d[p/T]/ dt = [- 4.5/28 × 8.314]/0.15 = - 8.9 × 10⁻⁵ bar/K.s.

Thus, there is the need to integrate, Integrate [p/T]f = 10/320 - 8.9 × 10⁻⁵ bar/K.s. ------------------------------------(2).

NB; fT = final temperature, fP = final pressure and iT = initial temperature.

Also, [ fT]³⁰/₈.₃₁₄/ [fP] = [iT]³⁰/₈.₃₁₄/ Pi] = [ 320]³⁰/₈.₃₁₄/ 10.

Therefore, [fT]³⁰/₈.₃₁₄ = 109.52 × 10⁶.

Final temperature=  [fP]³⁰/₈.₃₁₄ × 169.05.

Note that fP/ [fP]³⁰/₈.₃₁₄ × 169.05 = 10/320 - 8.9 × 10⁻⁵.

Therefore, [fP]¹ ⁻ ³⁰/₈.₃₁₄ = 0.7651.

Hence, Final temperature = 152.57K,

Pressure = 0.6907 bar

dT/ dt = N[RT]² / Cv . PV.

R = 30 - 8.314 = 21.86 J/mol K.

Then, the rate of change of the gas temperature at this time = dT/dt = - 1,151 K/s.

What are the characteristics of a metallic bond? PLEASE HELP

Answers

Answer: Metallic bonding is a type of chemical bonding and is responsible for several characteristic properties of metals such as their shiny lustre, their malleability, and their conductivities for heat and electricity. Both metallic and covalent bonding can be observed in some metal samples

PLEASE MARK ME BRAINLIST

Electrons move freely among positively charged ions. This is the characteristics of a metallic bond. Therefore, the correct option is option B.

Valence electrons in a metallic link are not bound to a specific pair of atoms, but rather travel freely among a "sea" of positively charged metal ions. These electrons are not assigned to any specific atom and are shared by all metal ions in the metallic lattice.

The electron sea model depicts the valence electron arrangement as a "sea" of negatively charged electrons encircling positively charged metal ions. Metals have strong electrical and thermal conductivity due to electron mobility.

Therefore, the correct option is option B.
