How many photons are contained in a burst of yellow light (589 nm) from a sodium lamp that contains 623 kJ of energy?
Goryan [66]
<span>First we need to find the energy of one photon with a wavelength of 589 nm. E = hc / wavelength E = (6.63 x 10^{-34} J s)(3 x 10^8 m/s) / (589 x 10^{-9} m) E = 3.3769 x 10^{-19} Joules To find N, the number of photons, we need to divide the total energy by the energy of each photon. N = 623000 J / 3.3769 x 10^{-19} Joules N = 1.84 x 10^{24} photons There are 1.84 x 10^{24} photons in the burst of yellow light.</span>

During mitosis, this structure moves individual chromosomes?
stiv31 [10]

Answer:

Anaphase

Explanation:

Two separate classes of movements occur during anaphase. During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the non-kinetochore microtubules move past each other.

How many atoms are there in 3.559*10^-6 mol of krypton?
algol [13]

Answer:

The answer is

<h2>2.143 \times  {10}^{18}  \:  \: atoms</h2>

Explanation:

To find the number of atoms given the number of moles we use the formula

N = n × L

where

N is the number of entities

n is the number of moles

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

n = 3.559 \times  {10}^{ - 6}  \: mol

Substitute the values into the above formula and solve

That's

<h3>N  = 3.559 \times  {10}^{ - 6}  \times 6.02 \times  {10}^{23}  \\  = 2.1425 \times  {10}^{18}</h3>

We have the final answer as

<h3>N  = 2.143 \times  {10}^{18}  \:  \: atoms</h3>

Hope this helps you
