Is hydrogen a neutral atom or ion

Chemistry
2 answers:
Sloan [31]2 years ago
4 0

Answer:

Hydrogen is the smallest chemical element. It has one proton and one electron, making it neutral. However, the ions of hydrogen atom are charged species. Thus, the key difference between hydrogen atom and hydrogen ion is that the hydrogen atom is neutral whereas hydrogen ion carries a charge.

Answer:

A normal hydrogen (H) atom does not have any neutrons in its tiny nucleus. That tiny little atom (the tiniest of all) has only one electron and one proton. You can take away the electron and make an ion, but you can't take away any neutrons.

An important reaction in the formation of photochemical smog is the photodissociation of NO2: NO2 + hv >>> NO(g) + O(g)
vaieri [72.5K]

Explanation:

NO_2 + hv\rightarrow NO(g) + O(g)

The maximum wavelength of light that can cause this reaction is 420 nm.

a) The wavelength given lies in the range of visible light range that is from 400 nano meters to 700 nano meters.

The light with wavelength of 420 nm is found in the range of visible light.

b)The maximum strength of a bond :

E=\frac{h\times c}{\lambda}

where,

E = energy of photon = Energy required to break single molecule of nitrogen dioxide

h = Planck's constant = 6.626\times 10^{-34}Js

c = speed of light = 3\times 10^8m/s

\lambda = wavelength = 420 nm=420\times 10^{-9}m

E=\frac{6.626\times 10^{-34}Js\times 3\times 10^8 m/s}{420\times 10^{-9}m}

E=4.733\times 10^{-19} J

Energy required to break 1 mole of nitrogen dioxide molecules:

= E\times N_A=4.733\times 10^{-19} J\times 6.022\times 10^{23} mol^{-1}

=285,012.66 J/mol=285.13 kJ/mol

(1 J = 0.001 kJ )

285.13 is the maximum strength of a bond, in kJ/mol, that can be broken by absorption of a photon of 420-nm light.

c) the photodissociation reaction showing Lewis-dot structures is given in an image attached.

Germanium and chlorine react according to the following chemical equation:
seropon [69]

The mass of GeCl4 that would be formed will be 1.51 g

<h3>Stoichiometric calculations</h3>

From the balanced equation of the reaction:

Ge (s) + 2Cl2 (g) →GeCl4

The mole ratio of Ge and Cl2 is 1:2.

Mole of 1.0 g Ge: 1/72.64

                               = 0.01377 mole

Mole of 1.0 g Cl2 = 1/71

                             = 0.01408 mole

Thus, Cl2 is limiting.

Mole ratio of Cl2 and GeCl4 = 2:1

Equivalent mole of GeCl4 = 0.01408/2

                                       = 0.0070 mole

Mass of 0.0070 mole GeCl4 = 0.0070 x 214.4

                                               = 1.51 g
