<span>When the electron in a hydrogen atom transitions from a high energy state to a lower energy state, the energy lost from the electron is used to produce a photon corresponding to the loss of energy. That photon will correspond to exactly 1 wavelength. And since a hydrogen atom has only 1 electron, at any given moment, it can only produce 1 photon. And in order to simultaneously produce 4 photons for 4 spectral lines, that would require a simultaneous transition of 4 electrons which is 3 too many for a hydrogen atom.</span>

What is the molarity of a naoh solution if 39.1 ml of a 0.112 m h2so4 solution is required to neutralize a 25.0-ml sample of the
aleksandrvk [35]
The reaction between NaOH and H₂SO₄ is as follows;
2NaOH + H₂SO₄ ---> Na₂SO₄ + 2H₂O
stoichiometry  of base to acid is 2:1
NaOH is a strong acid and H₂SO₄ is a strong acid, therefore complete ionization into their respective ions takes place.
number of acid moles reacted - 0.112 M / 1000 mL/L x 39.1 mL = 0.0044 mol
the number of base moles required for neutralisation = 0.0044 x 2 = 0.0088 mol
Number of NaOH moles in 25.0 mL - 0.0088 mol
Therefore in 1000 mL  - 0.0088 mol/ 25.0 mL x 1000 mL/L = 0.352 mol/L
Therefore molarity of NaOH - 0.352 M

An unknown compound does not dissolve in water, is a nonelectrolyte and has a low melting point. Would it be an ionic compound?
Leviafan [203]
No, it's not an ionic compound.
The distinguishing properties of ionic compounds are that they dissolve in water (water's polarity pulls the ions apart), are electrolytes (dissociate into ions, which conduct electricity), and have high melting points (it takes a lot of energy to separate the ions without water or other polar compounds). Since the unknown compound has the opposite of all these properties, it's not ionic.

Aphelion in miles =94290301

Perihelion in miles = 91200281

Explanation:

To convert km in mile we use the multiply the distance in km with 0.62, because there are 0.62 miles in 1 km.

Aphelion in miles = aphelion in km × 0.62

Aphelion in miles = 152081132 × 0.62

Aphelion in miles =94290301

Perihelion in miles = perihelion in km × 0.62

Perihelion in miles = 147097229 × 0.62

Perihelion in miles = 91200281
