Frequency of photon = is 6.85 X 10¹⁴ sec⁻¹

Energy of photon , E = hv

where h is Planck's constant, v is the frequency of photon

E = 6.63 × 10⁻³⁴ J.s x 6.85 X 10¹⁴ s⁻¹

E = 4.54 x 10⁻¹⁹ J

Therefore, the energy of a photon of green light is 4.54 x 10⁻¹⁹ J.

What is the minimum number of moles of potassium permanganate that would be required to completely oxidize 1.0 moles of benzalde
makvit [3.9K]
Mole ratio :

<span>5 C</span>₆<span>H</span>₆<span>CHO + 2 KMnO</span>₄<span> + 6 H</span>⁺ <span>= 5 C</span>₆<span>H</span>₆<span>COOH + 2 Mn</span>²⁺<span> + 3 H</span>₂<span>O + 2 K</span>⁺

5 moles C₆H₆CHO ------------------ 2 moles KMnO₄
1.0 moles C₆H₆CHO ---------------- ( moles of KMnO₄ )

moles of KMnO₄ = 1.0 x 2 / 5

moles of KMnO₄ = 2 / 5

= 0.40 moles of KMnO4

hope this helps!

Are the noble gases considered inert or reactive? Why?
mr Goodwill [35]

Answer:

Noble gases are considered as Inert because they are unreactive.

Explanation:

Seven noble elments are known to us , they are: helium, neon, argon, krypton, xenon, radon, and oganesson. Noble gases have 8 electrons in their outermost shell and hence their valence shell is complete, they donot need further electrons to complete their octet so they are unreactive. Also they posses following properties.
