The equilibrium constant, k, for a redox reaction at 25° c is 7.3 × 107. what is the value of e° if the overall reaction transfe
Novay_Z [31]

Answer:

0.23 V.

Explanation:

<em>∵ ΔG° = -RT lnK.</em>

∴ ΔG° = -RTlnK = -(8.314 J/mol)(298 K) ln(7.3 × 10⁷) = - 44.86 x 10³ J/mol.

<em>∵ ΔG° = - nFE°</em>

∴ E° = - ΔG°/nF = - (- 44.86 x 10³ J/mol)/(2 x 96500 s.A/mol) = 0.2324 V ≅ 0.23 V.

When 3243. grams of iron (III) chloride are reacted with 511.8 grams of hydrosulfuric acid, which is the limiting reactant?
AleksAgata [21]

Answer:

Hydrosulfuric acid will act as limiting reactant.

Explanation:

Given data:

Mass of iron(III) chloride = 3243.0 g

Mass of hydrosulfuric acid = 511.8 g

Limiting reactant = ?

Solution:

Chemical equation:

2FeCl₃ + 3H₂S       →       Fe₂S₃ + 6HCl

Number of moles of iron(III) chloride:

Number of moles = mass/molar mass

Number of moles = 3243.0 g/ 162.2 g/mol

Number of moles = 20 mol

Number of moles of hydrosulfuric acid:

Number of moles = mass/molar mass

Number of moles = 511.8 g/ 34.1 g/mol

Number of moles = 15 mol

Now we will compare the moles of both reactant with products

                      FeCl₃          :          Fe₂S₃

                       2                :            1

                      20               :          1/2 ×20 = 10

                      FeCl₃          :            HCl

                       2                :              6

                      20               :          6/2 ×20 = 60

                      H₂S             :          Fe₂S₃

                       3                :            1

                      15               :          1/3 ×15 = 5

                      H₂S            :            HCl

                       3                :              6

                      15                :          6/3 ×15 = 30

Hydrosulfuric acid producing less number of moles of product thus, it will act as limiting reactant.

torisob [31]

Answer:

Water, 35 liters. Carbon, 20 kilograms. Ammonia, 4 liters. Lime, 1.5 kilograms. Phosphorous, 800 grams. Salt, 250 grams. Saltpeter, 100 grams. Sulfur, 80 grams. Fluorine, seven-point-five. Iron, five. Silicon, three grams. And trace

amounts of 15 other elements.

the ingredients of the average adult,right down to the last specks of protein in your eyelashes. And even though science has given us the entire physical breakdown, there's never been a successful attempt at bringing a human to life. There's still something missing. Something scientists haven't been able to find in centuries of research. ...and in case you're wondering, all those ingredients can be bought on a child's allowance. humans can be made rather cheap. There's no magic to it.

Apply the rules and principles of electron configuration to draw the orbital diagram of aluminum. Use the periodic table to help
fredd [130]

The electronic configuration of Aluminum is 2,8,3.

<h3><u>Explanation:</u></h3>

Aluminum is a metallic element belonging to group 3 of periodic table. Its atomic number is 13.

The rules of electronic configuration is

A. The maximum number of electrons a shell can hold is determined by 2n² where n is the shell number numbered from the one as 1 which is nearest to the nucleus.

B. Each shell has some subshells which actually holds the electrons. Shell 1 has only s subshell where as shell 2 has s and p subshells and so on.

C. Afbau's principle states which subshell of which shell is first filled. For example, 4s subshell is filled before 3d subshell which is stated by Afbau's principle.

The atomic number 13 is filled like- 1st shell has 2 electrons, 2nd shell has 8 electrons and 3rd shell has 3 electrons.

It is also represented as 1s², 2s²,2p⁶, 3s² 3p¹.
