this shows that magnesium is higher in the reactivity series than lead.

I don't think there can be an ionic equation written because both components are in solid form and neither is in an aqeuos state.

Carbon-carbon bonds form the ""backbone"" of nearly every organic and biological molecule. The average bond energy of the C¬C bo
qwelly [4]

1.17 × 10¹⁵ s⁻¹ is the frequency and the wavelength is 3.43 × 10⁻⁷m of the least energetic photon that can break an average C - C bond.

WHAT IS CARBON BACKBONE ?

The carbon backbone is also called the carbon skeleton. All organic compounds are made up of carbon-carbon bonds, creating a carbon skeleton or backbone in the compounds.

Carbon Skeleton Structure :

The carbon skeleton structures consist of bending lines, periodically other elements are written in as well. The carbon skeleton characteristics that change the overall structure includes:

  • Length of carbon chain (the longer it is the more zig-zags are drawn).
  • Shape of the carbon chain (branches, rings, etc. all change the shape of the skeleton).
  • Location of attached functional groups, they need to be put onto the correct point in the skeleton.
  • Any double or triple bonds that are present, particularly as triple bonds change the shape of the skeleton.

<h3>What is wavelength?</h3>

Forms of electromagnetic radiation like radio waves, light waves or infrared (heat) waves make characteristic patterns as they travel through space. Each wave has a certain shape and length. The distance between peaks (high points) is called wavelength.

Step 1 :

Here we have to calculate the frequency and wavelength of the least energetic photon that can break an average C - C bond and have to find out in what region of the electromagnetic spectrum is this radiation.

Bond energy of C - C = 347 kJ

It is known that E = hv

           ⇒ mu = \frac{E}{h}

Where, E is the energy = 347kJ

            h is the planck's constant = 6.626 * 10^{-34}J.s

            v is the frequency

Now substituting the values, frequency can be calculated as,

             ⇒ v = \frac{E}{h} = \frac{347kJ/1kJ * mol/6.022 * 10^{23}}{6.626 * 10^{-34}J.s}

                             ≈ 8.70 × 10¹⁴ s⁻¹ .

Formula of Wavelength :

              \lambda = \frac{hc}{E}

Where, λ = wavelength

            h = 6.6 × 10⁻³⁴

            c = 3 × 10⁸

            E = bond energy

Now substituting the values, wavelength can be calculated as,

\lambda = \frac{hc}{E} = \frac{6.6 * 10^{-34} * 3 * 10^{8} * 6.023 * 10^{23}}{347 * 10^{3}} = \frac{119.255 * 10^{-34} * 10^{31} * 10^{-3}}{347} = 0.343 * 10^{-6} = 3.43*10^{-7} m

Thus, from the above conclusion we can say that 1.17 × 10¹⁵ s⁻¹ is the frequency and the wavelength is 3.43 × 10⁻⁷ m of the least energetic photon that can break an average C - C bond.

Pressure is the force exerted by a substance on its container. Of the three phases of matter which one would exert the highest p
Luden [163]

Answer:

Gaseous phase exert more pressure on container.

Explanation:

Pressure:

It is the force exerted by the substance on its container.

Mathematical expression:

P = F/A

P = pressure

F = force

A = area

We know that there are phases of matter solid liquid and gas.

Gases don't have definite volume and shape and take the shape and volume of container in which it present.  Molecule of gases randomly move everywhere and occupy all available space.  The molecules of gas randomly move collide with each other and also the wall of container their kinetic energy also increased because of this collision and pressure is produced

While in case of liquid molecules are packed and they can not move freely thus did not exert pressure like gaseous molecules.

In case of solids molecules are tightly packed and form more compact structure. They can not move thus did not exert pressure to the wall of container.

Properties of gases:

Molecule of gases randomly move everywhere and occupy all available space.

Gases don't have definite volume and shape and take the shape and volume of container in which it present.

Their densities are very low as compared to the liquid and solids.

Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.

The very weak inter molecular forces are present between gas molecules.

Properties of Liquid:

Liquid have definite volume but don,t have definite shape.

Their densities are high as compared to the gases but low as compared to the solids.

In liquid, molecules are close to each other and have greater inter molecular forces as compared to the gas molecules.

Properties of solids:

Solids have definite volume and shape.

In solids molecules are tightly pack and very close to each other.

Their melting and boiling point are every high.

The densities of solids are also very high as compared to the liquid and gas.

There are very strong inter molecular forces are present between solid molecules.
