Answer:
From n=1 to n=2
Explanation:
Electrons in n=1 are strongly attracted to the nucleus and therefore will require great force to overcome the electrostatic force of attraction to displace them from the energy level to another.
The electrostatic force reduces as you progress to the outer energy levels.
In acidic solutions you have H+ but in basic solutions you have OH-.
You need know that for to balance the reaction.
Answer:
4.52 x 10¹⁴ cycles/s
Explanation:
From c = f·λ => f = c/λ = (3.0 x 10⁸ m/s)/(6.63 x 10⁻⁷m) = 4.52 x 10¹⁴ cycles/s.
f = frequency = ?
λ = wavelength = 6.63 x 10⁻⁷ meter
c = speed of light in vacuum = 3.0 x 10⁸ meters/s
Their should be two molecules of hydrogen (h2) to produce 2 moles of h2O2
The answer is electromagnetism.
The definition of electromagnetic is:
relating to the interrelation of electric currents or fields and magnetic fields.
Therefore, the verb form of electromagnetic would be ELECTRONAGNETISM
