draw a structure for a ketone that exhibits a molecular ion at m = 86 and that produces fragments at m/z = 71 and m/z = 43.

Answers

Answer 1

Without additional information, it is not possible to determine the specific structure of the ketone that exhibits a molecular ion at m/z = 86 and produces fragments at m/z = 71 and m/z = 43.

What is the structure of a ketone that exhibits a molecular ion at m/z = 86 and produces fragments at m/z = 71 and m/z = 43?

Based on the given information, the molecular ion (M) has a mass (m) of 86, and the compound produces fragments with mass-to-charge ratios (m/z) of 71 and 43.

Without additional information about the specific arrangement of atoms in the ketone molecule, it is challenging to provide a specific structure.

Ketones have a general molecular formula of R-CO-R', where R and R' can be various organic groups.

To determine the specific structure, additional details such as the number and types of substituents or functional groups attached to the ketone are needed.

With that information, it would be possible to propose a more accurate structure that matches the given mass and fragmentation patterns.

how many grams of fertilizer , for potassium sulfate are there in 42.3 mole of potassium sulfate? step by step

Answers

Answer:

The mass of 42.3 moles of potassium sulfate is 7,371.1557 grams

Explanation:

Potassium sulfate K₂SO₄ which is also known as sulphate of potash is a water soluble common component of fertilizer

The molar mass of potassium sulfate, M = 174.259 g/mol

The given number of moles of potassium sulfate, n = 42.3 moles

The mass, 'm', of a given number of moles of potassium sulfate, 'n', is given as follows;

m = n × M

Therefore, we have;

The mass, 'm', of 42.3 moles of potassium sulfate is found by plugging in the values for 'M', and 'n', in the above equation as follows;

m = 42.3 moles × 174.259 g/mol = 7,371.1557 grams

The mass of 42.3 moles of potassium sulfate, m = 7,371.1557 grams.

The F1-ion is classified as a(n).
and has:
A.anion, 1 valence electron
B.anion, 8 valence electrons
C.cation, 2 valence electrons
D.cation, O valence electrons

Answers

Answer:

B

Explanation:

The [tex]\rm \bold{F^1^-}[/tex] is the fluorine anion with 8 valence electrons. Hence, option B is correct.

An ion is defined as the atom with the change in the valence electrons by the loss or gain of electrons to complete the outer shell.

What type of ion is [tex]\rm F^1^-[/tex]?

The ions with the gain of electrons result in a negative charge and are termed anions. The ions with a loss of electrons have a positive charge and are termed cations.

The F is the halogen atom of group 17 with 7 valence electrons. The ion formed for F requires 1 electron to complete its valence shell.

The ion [tex]\rm F^1^-[/tex] has a negative charge, which denotes it gains an electron and forms anion.

The gain of electrons results in the number of valence electrons being 8.

Thus, [tex]\rm F^1^-[/tex] is the fluorine anion with 8 valence electrons. Hence, option B is correct.

[please answer fast!] If the hydroxide ion concentration is 2x10^-3 M, what is the pH of the solution? Show your working.

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

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⁻]

I don’t know how to calculate the error %
The formula is:
%Error = [I Accepted value-Experimental value I / Experimental value] x 100 can someone please PLEASE help me :(

Answers

Answer:

Explanation:

I gave this formula as

What you should get - what you got

---------------------------------------------------   * 100

What you should get

Suppose you are talking about the specific heat of copper and you did a lab and did it fairly well and the specific heat came out to be 0.33

That's what you got, 0.33

What you should get is 0.35 according to the table you've given us.

% error = 0.35 - 0.33

                -------------- * 100

                      0.35

% error = 0.02 * 100/ 0.35

% error = 2/0.35

% error = 5.71

Now here is the really hard part. You have to decide what a positive error is and what a negative error.

A positive error using this formula means you are too low.

A Negative error means that you are too high, just the opposite of what you might think.

Can you show us the experimental value?

So basically, the accepted value would be under the Specific heat capacity of metal (e.g. 0.90, 0.35, 0.44, 0.12).

Your experimental value would be the specific heat capacity that you got from the lab.

You would first substract the experimental value from the accepted value

[tex]accepted \: value - experimental \: value [/tex]

and then you would divide the result by the experimental value

[tex]result \div experimental \: value[/tex]

and then, you would multiply the result of that by a hundred to get your percentage

[tex]result \times 100 = \% \: error[/tex]

//

The image shown is an example.

0.90 is our accepted value.

0.88 is our experimental value.

The overall percentage error I got is %2.27

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

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.
