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

What is the importance of protons ?

Answers

Protons are important because they help keep the nucleus together, they also attract negatively charged electrons and keep them in orbit around the nucleus.

The protons inside a atoms nucleus help to bind the nucleus together. They attract the negative charged electrons and keep them in orbit around the nucleus. The number of protons in an atoms nucleus determine which chemical element it is

Given the standard heats of reaction

Reaction ∆H 0

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
