M(s) + 2 X2(g) → MX4(g) −98.7 kJ/mol

X2(g) → 2 X(g) +327.3 kJ/mol

M(g) → M(s) −20.1 kJ/mol


calculate the average bond energy for a single

M-X bond.

Answer in units of kJ/mol.

Answers

Answer:

Explanation:

M(s) → M (g ) + 20.1 kJ --- ( 1 )

X₂ ( g ) → 2X (g ) + 327.3 kJ ---- ( 2 )

M( s) + 2 X₂(g) → M X₄ (g ) - 98.7 kJ ----- ( 3 )

( 3 ) - 2 x ( 2 ) - ( 1 )

M( s) + 2 X₂(g) - 2 X₂ ( g ) - M(s)  → M X₄ (g ) - 98.7 kJ -  2 [ 2X (g ) + 327.3 kJ ] - M (g ) - 20.1 kJ

0 = M X₄ (g ) - 4 X (g ) - M (g ) - 773.4 kJ

4 X (g ) +  M (g ) =  M X₄ (g ) - 773.4kJ

heat of formation of M X₄ (g ) is - 773.4 kJ

Bond energy of one M - X bond =  773.4 / 4 =  193.4 kJ / mole

calculate the oxidation number of s in S2O8^2-​

Answers

Given problem:

    S₂O₈²⁻

Find the oxidation number of S;

Oxidation number presents the extent of oxidation of each atom of elements a molecular formular or formula unit or an ionic radical.

  For radicals:

          "the algebraic sum of all the oxidation numbers of all atoms in an ion containing more than one kind of atom is equal to the charge on the ion  "

 S₂O₈²⁻;   oxidation number of O is usually -2

             2(S) + 8(-2) = -2

               2S - 16  = -2

               2S = -2 + 16

                2S  = 14

                   S  = +7

The oxidation state of S in the radical is +7

If a can of soup 150 g mass and 0.75g/ cm^3 density what’s the volume

Answers

Answer:

The answer is 200 cm³

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density}\\[/tex]

From the question

mass = 150 g

density = 0.75 g/cm³

We have

[tex]volume = \frac{150}{0.75} \\ [/tex]

We have the final answer as

200 cm³

C++12.18 Lab - StructsIn this lab, you will familiarize yourself with structs through a small exercise. We will be mixing the RGB values of colors together to make a new one.RGB stands for red, green and blue. Each element describes the intensity value ranging from 0 - 255. For example: black color will have RGB values (0, 0, 0) while white will have (255, 255, 255).Create an array of structs color. The struct contains three integers named red, green and blue. This corresponds to the RGB values of a color. For each array element, ask the user to enter the intensity value of red, green and blue. The value should be between 0 and 255 (inclusive).*********The user can enter at most 10 colors. ********. see below for inputsAdditionally, compute the average of each of the red, green and blue components. For code modularity, implement a function that returns the average of each rgb component in your dynamic array. The function (called average) should take in a struct array, the rgb type for which you want to compute the average (as a string - red, blue or green) and its length. Print out the final result in the form (r, g, b), where r, g, b corresponds to each averaged value.Can you guess what color you mixed?
