Answer:
1.82x10⁻¹⁹Joules is the energy of the photon that is absorbed by the electron.
Explanation:
The energy of a photon is given by the equation:
E = h×ν
<em>Where E is energy of the photon in Joules.</em>
<em>h is Planck's constant (6.6262x10⁻³⁴Js)</em>
<em>And ν is frequency of the photon (In Hz = s⁻¹)</em>
<em />
The frequency of the photon is 2.74x10¹⁴Hz. That means its energy is:
E = 6.6262x10⁻³⁴Js × 2.74x10¹⁴s⁻¹
E =
<h3>1.82x10⁻¹⁹Joules is the energy of the photon that is absorbed by the electron</h3>

Answer:
677
Explanation:
took the test
it said that it was wrong but then it also said the total bond energy of the reactants is 677 kJ/mol. the correct one was 854, i guess.
Answer:
No.2, No.3 and No.4 answers are same. Give the options properly.
Answer:
higher, higher
Explanation:
It takes more energy to rip apart stronger bonds (that's mostly just common sense there). The boiling point increases because it would take more energy to get the molecules to go from a stuck together liquid, to separating in a gaseous form.
Answer:
Classifying stars according to their spectrum is a very powerful way to begin to understand how they work. As we said last time, the spectral sequence O, B, A, F, G, K, M is a temperature sequence, with the hottest stars being of type O (surface temperatures 30,000-40,000 K), and the coolest stars being of type M (surface temperatures around 3,000 K). Because hot stars are blue, and cool stars are red, the temperature sequence is also a color sequence. It is sometimes helpful, though, to classify objects according to two different properties. Let's say we try to classify stars according to their apparent brightness, also. We could make a plot with color on one axis, and apparent brightness on the other axis, like this:
