Answer:
universe, galaxy, solar system, planet
The answer is the coefficient is "1".
C₅H₁₀, now you see that there is no number with this and when there is no number or digit, it means the coefficient is one.
we use the coefficients to balance the equation of the reaction in such a way that number of the atoms of the elements in the reactants are equal to the number of atoms of different elements in the product, so that both sides are equal and balanced.
Refraction is the phenomenon of change in the speed of light when the light when passes from the medium of one optical density to a medium of another optical density. The light rays also show a bending when passing through the interface of such a medium.
<h3>What causes wave refraction?</h3>
Refraction is the bending of waves due to a change in speed as they travel through different media. Waves may accelerate or decelerate when they go obliquely from one medium to another. The waves will bend more dramatically as their speed changes.
<h3>What characteristics does a wave have?</h3>
The following characteristics of waves:
- Refraction is the bending of waves as they move from one medium to another due to a change in their speed.
- Waves may speed up or slow down as they transition from one medium to another at an angle.

The correct answer to this question is this one:
find the energy of one photon:
<span>E=h*<span>c/λ
</span></span>
divide the energy given by the energy of one photon of that wavelength
What I've done so far is convert wave length to m and energy to j.
E photon = h * x / wave length
E = (6.626 x 10^-43)(3.00 x 10^8) / 587 ^ -9 = 3.38 x 10 ^18 J
3.38 x 10 ^18 J x 1000 kj / 1 j = 3.37 x 10 ^ 16 Kj
609 kJ/ 3.37 x 10 ^ 16 Kj = 1.81 x 10 ^ 16
E = (6.626 x 10^-34)(3.00 x 10^8) / 587 ^ -9 = 3.38 x 10 ^19 J
3.38 x 10 ^19 J x 1000 kj / 1 j = 3.37 x 10 ^ -16 Kj
609 kJ/ 3.37 x 10 ^ 16 Kj = 1.81 x 10 ^ 18 but the answer is 1.81 × 10^24 photons
3.38 x 10 ^-19 J
should be negative
then 3.38 x 10 ^18 J x 1kJ/1000 J
you're converting from J to kJ.. just like meters to kilometres, you wouldn't multiply you would divide
