The hydrogen emission spectrum is shown below. What is the energy of the 434 nm emission line? (The speed of light in a vacuum is 3.00 x 108 m/s, and Planck's constant is 6.626 X 10 34 J·s.) 760 nm

E=hv

where v= c/wave function (lambda)

E=hc/lambda

E=6.626×10^34 × 3×10^8/434

E=19.878×10^42/434

E=0.046×10^42

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
