The energy released when electron move from n=4 to n=3 is 0.66 eV

We know that in an atom energy of nth state is

$E_n = -13.6/n^{2}$ eV

where n is the energy level

Therefore,

$E_4 = -13.6/4^{2} \\E_3 = -13.6/3^{2}$

Thus, $E_4$ = -0.85eV

$E_3$ = -1.51eV

Therefore, total mount of energy released in moving electron from n=4 to n=3 is given by -

$E_4 -E_3$

= -0.85 - ( -1.51)

= 0.66eV

If 500ml of H₂ gas at 600mmHg and 400ml of CO₂ gas at 700mmHg are mixed in a 1 lit vessel, find the total pressure of mixture of

seraphim [82]

Answer:

Total pressure increased

Explanation:

When gas C is added in the vessel then number of mole increases and number of collision depends on the number of molecules present in the vessel and on adding gas C ,mole also increases hence number of collision increases therefore pressure also increases because number of collision increases.

Total pressure increases.

What is the hydrogen ion (H+) concentration of a solution of pH 8?

fgiga [73]

Answer:

10−8 M.

Explanation:

In this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,

− pH = log [H+] ,

[H+] = 10−pH,

by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,

[H+] = 10−7.4 ≈ 0.0000040 = 4.0 × In this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,

Explain how a hurricane poses a threat to life and the biosphere. Use complete sentences.

Snezhnost [94]

Answer:

A hurricane can cause extreme damage to the biosphere and the geosphere. A hurricane can leave water standing therefore sinking itself into the geosphere. The biosphere can be permanently effected because it can kill, injure, and destroy the biosphere and what the biosphere creates (buildings, parks).
