A compound has the formula X2Fe(CN)6 ∙ 12H2O, where X is an unknown element. [3]
If the compound is 45.34% water by mass, what is the identity of element X?

Answers

Answer 1

The element X from the calculation is Cs.

What is the identity of element X?

We have in the question the percentage by mass of water as  45.34% thus we can write;

45.34% = 12(H20)/2(X) + Fe + 6(CN)

Hence;

45.34/100 = 12(18)/2X + 56 + 6(26)

0.45 = 216/2X + 56 + 156

0.45 = 216/2X + 212

0.45(2X + 212) = 216

0.9X + 95.4 = 216

X = 216 -  95.4/0.9

X = 134

The element X from the calculation is Cs.

Answer:

70.9 g/mol

Explanation:

To find the molar mass, you first need to convert molecules to moles via Avogadro's Number.

Avogadro's Number:

6.022 x 10²³ molecules = 1 mole

2.123 x 10²¹ molecules X₂                      1 mole
--------------------------------------  x  ------------------------------------  = 0.00353 moles X₂
                                                   6.022 x 10²³ molecules

Now, you can plug the molar value and mass (given) into the molar mass ratio to find your final answer. Your answer should have 3 sig figs to reflect the given value with the lowest amount of sig figs (0.250 g).

Molar Mass (g/mol) = mass (g) / moles

Molar Mass = 0.250 g / 0.00353 moles

Molar Mass = 70.9 g/mol

Uric acid can collect in joints, giving rise to a medical condition known as gout. If the pKa of uric acid is 3.89, what is the pH of a 0.0140 M solution of uric acid?

Answers

Answer:

The pH of the solution is 2.873

Explanation:

Given:

Pka = 3.89pH of a 0.0140 M

Let the solution of the uric acid be HA. We have to set up the ICE table as follows;

        HA(aq) + H20(l)  ⇄ H3O^+(aq)  + A^-

I         0.0140                       0                 0

C       -x                                +x                +x

E    0.0140 - x                      x                   x

Ka = 10^-(pka)

    = 10^-3.89

    = 1.28 x 10^-4

Ka = [H+] * [A-]/[HA]

=> 1.28 x 10^-4 = [H+]^2 / 0.0140

=>[H+]^2 = 1.28 x 10^-4 x 0.014

=> [ H+] = 1.338656 x 10^-3

so pH = - log [ H+ ] =  - log  1.338656 x 10^-3

= 3 - log 1.338656

= 2.87333101111

The hydronium ion concentration of a solution is 2.4 x 10-4.
a. Calculate the pH of the solution.
b. Calculate the pOH of the solution.
c. Calculate the hydroxide ion concentration of the solution

Answers

Answer:

a.) pH = 3.62

b.) pOH = 10.38

c.) [OH⁻] = 4.17 x 10⁻¹¹

Explanation:

The hydronium ion concentration can be represented by the symbol: [H₃O⁺]. The hydroxide ion concentration can be represented by the symbol: [OH⁻].

a.) The pH of a solution represents the hydrogen (hydronium) ion concentration. It can be calculated using the following formula:

pH = -log[H₃O⁺]

Since you have been given the hydronium concentration, you can easily find the pH.

[H₃O⁺] = 2.4 x 10⁻⁴

pH = -log[2.4 x 10⁻⁴]

pH = 3.62

b.) The pOH of a solution represents the hydroxide concentration. It measures the opposite of the pH measurement. Since the pH range goes up to 14, you can find the pOH using the following formula:

pOH + pH = 14

Since you now know the value of the pH, you can plug it into the formula to find the pOH.

pOH + 3.62 = 14

pOH = 10.38

c.) You can find the hydroxide concentration using the following formula:

[OH⁻] = 10^-pOH

Since you now know the value of the pOH, you can plug it into the formula to find the hydroxide concentration.

[OH⁻] = 10⁻¹⁰°³⁸

[OH⁻] = 4.17 x 10⁻¹¹

If the compounds/elements appear on both the reactants and products side of the equation, they will not be found it the net ionic equation.

Answers

Answer:

The wavelength of a photon with an energy of 4.56×10⁻¹⁹ J is 463nm (nanometer)

Define the wavelength of a photon.

Each photon has a wavelength and a frequency. The wavelength is defined as the distance between two peaks of the electric field with the same vector.

A photon is the smallest element of electromagnetic radiation. You can think of a photon as a packet of energy travelling at the speed of light. There is no constant wavelength of a photon, it is dependent on how much energy the photon carries.

The mathematical relationship can be written as

E=hc/ λ

In terms of wavelength,

λ=hc/E

- h is planks constant

- c is the speed of light

- E is the energy of the photon

Where h = 6.626×10⁻³⁴ J⋅s is Planck’s constant and c = 3×10⁸ m/s is the speed of light.

If E = 4.56×10⁻¹⁹ J then λ = 463nm (nano meter)

The balanced equation of H2 + Cl2 —-> HCl is 2H2 + 2Cl2 —-> 2HCl.

Explanation:

In a chemical reaction, the number of atoms of each element must be the same on both sides of the equation. In this case, there are two atoms of hydrogen on the left side and two atoms of chlorine. On the right side, there is one atom of hydrogen and one atom of chlorine. In order to balance the equation, we must add another chlorine atom to the right side so that there are two atoms of chlorine on both sides of the equation.

Explanation:

Thats the percent composition for each one in your question

Answer:

Hello! The answer to your question is:

Mg: 41.68%

O2: 54.86%

H2: 3.46%

Explanation:

We need to find the percent composition of each element, so first, we need to find the molar mass. This is calculated by using the number underneath the element. The "2" outside of the parentheses is distributed to Oxygen and Hydrogen as well-meaning that you multiply the number by 2:

Mg: 24.31 g/mol

O2: 16.00 × 2 = 32.00 g/mol

H2: 1.01 × 2 = 2.02 g/mol

Now, we have to add up the molar mass of each element:

24.31 g/mol + 32.00 g/mol + 2.02 g/mol = 58.33

To find the percent composition of each element, you have to divide the molar mass of each element by the total molar mass:

Mg: [tex]\frac{24.31 g/mol}{58.33 g/mol} \\= 41.68 percent[/tex]

O2: [tex]\frac{32.00 g/mol}{58.33 g/mol} \\= 54.86 percent[/tex]

H2: [tex]\frac{2.02 g/mol}{58.33 g/mol} \\= 3.46 percent[/tex]

The percent composition of each element is:

Mg: 41.68%

O2: 54.86%

H2: 3.46%

2.54 × 10⁵ kJ of heat are required to fully melt a 0.834 m³ block of ice, with a density of 917 kg / m³.

What is melting?

Melting is a physical change in which solids turn into liquids.

Step 1. Calculate the mass of ice.

We have a block of 0.834 m³ of ice with a density of 917 kg/m³.

0.834 m³ × 917 kg/m³ = 765 kg = 7.65 × 10⁵ g

Step 2. Convert 7.65 × 10⁵ g to moles.

We will use the molar mass of water.

7.65 × 10⁵ g × (1 mol/18,02 g) = 4.24 × 10⁴ mol

Step 3. Calculate the heat required to melt 4.24 × 10⁴ moles of water.

According to the thermochemical equation, 6.01 kJ are required to melt 1 mol of water.

4.24 × 10⁴ mol × (6.01 kJ/mol) = 2.54 × 10⁵ kJ

re-rrange to :

P1 V1 / T1  *  T2/V2  = P2

2.81 * 713 / (664)  *  368 /126  = 8.81 atm

The new pressure of the gas given that its volume and temperature change to 126 L and 368 K respectively is 8.81 atm

Data obtained from the question Initial pressure (P₁) = 2.81 atmInitial volume (V₁) = 713 L Initial temperature (T₁) = 664 K New Volume (V₂) = 126 L New temperature (T₂) = 368 KNew pressure (P₂) = ?

How to determine the new pressure

The new pressure of the gas can be obtained by using the combined gas equation as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

(2.81 × 713) / 664 = (P₂ × 126) / 368

Cross multiply

664 × 126 × P₂ = 2.81 × 713 × 368

Explanation:

A few common examples of exceptions to 18 electron rules include: 16-electron complexes: The metal center is usually low-spin and is in d8 configuration. These complexes adopt square planar structure, such as Rh(I), Ni(II), Pd(II), and Pt(II) complexes.
