Methane is not very reactive so it doesn't react with air when flame is not applied
<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>
Deuterium has one proton and one neutron, 12H, while tritium has one proton and two neutrons, 13H.
Hmm, I am not quite sure but if I am probably your best bet so I'd go with, either B or D.
