The energy of a hydrogen atom in energy level n = 2 is 3.4 eV.

The ionization of energy of the hydrogen atom is 13.6 eV.

This is the minimum energy required to raise the electron from its ground state in the hydrogen atom.

n represents the Energy level.

When an electron changes from one energy level to another, the energy of the atom must change as well.  It requires energy to promote an electron from a lower energy level to a higher one.  This energy can be supplied by a photon whose energy E is given in terms of its frequency E = hf or wavelength E = hc/λ.

The formula for the energy of an atom is:

E = 13.6 * Z^{2} / n^{2}  .... this represents the allowed energy level in the hydrogen       atom

  = 13.6 * 1 / 2^{2}    since Z = 1 for hydrogen where Z is mass of atom

  = 13.6 / 4

  = 3.4 eV

The energy of a hydrogen atom in energy level n = 2 is 3.4 eV.

Cl2 + 2OH− → Cl− + ClO− + H2O
Nataly_w [17]
Cl2(g) -------> Cl-(aq) + ClO-(aq) 

2e- + Cl2(g) -------> 2Cl-(aq) [reduction] 

4OH-(aq) + Cl2(g) -----------> 2ClO-(aq) + 2H2O(l) + 2e- [oxidation] 
______________________________________... 
2OH-(aq) + Cl2(g) --------> Cl-(aq) + ClO-(aq) + H2O(l)

Which statement best describes the properties of sucrose?
crimeas [40]

Answer:

D. They are different from the properties of carbon, oxygen, and hydrogen.  

Step-by-step explanation:

Carbon, oxygen, and hydrogen are all <em>elements. </em>

Sucrose is a <em>compound</em> containing carbon, oxygen, and hydrogen. Its properties are different from those of its elements.

For example, carbon is a <em>black solid,</em> while oxygen and hydrogen are <em>colourless gases</em>. Sucrose is a <em>white solid</em>.

Determine the [h3o+] of a 0.210 m solution of formic acid.
Nataly [62]
When the Pka for formic acid = 3.77
and Pka = -㏒ Ka 
   3.77 = -㏒ Ka
∴Ka = 1.7x10^-4 

when Ka = [H+][HCOO-}/[HCOOH]

when we have Ka = 1.7x10^-4 &[HCOOH] = 0.21 m
so by substitution: by using ICE table value
1.7x10^-4 = X*X / (0.21-X)
(1.7x10^-4)*(0.21-X) = X^2      by solving this equation for X

∴X = 0.0059
∴[H+] = 0.0059
∴PH= -㏒ [H+]
       = -㏒ 0.0059
       = 2.23
