We first need to calculate how much energy is needed to ionize a single atom. So divide the kilojoules/mol energy value by avogadro's number.
342 kj/mol / 6.0221409x10^23 = 5.67904x10^-19 Joules
So we need a photon with 5.67904x10^-19 Joules of energy. The equation to express the energy of a photon is
E = hc/w
where
h = Planck constant (6.626070040Ă—10â’34 Js)
c = speed of light (299792458 m/s)
w = wavelength of photon
Solving for w
E = hc/w
Ew = hc
w = hc/E
Substituting known values
w = 6.626070040Ă—10^â’34 Js * 299792458 m/s / 5.67904x10^-19 J
w = 1.9864458x10^-25 Jm / 5.67904x10^-19 J
w = 3.497855x10^-7 m
w = 3.50x10^-7 m
w = 350 nm</span>
Covalent bonds and it is between the hydrogens (hydrogen bonds)
Are there any answer choices?
Answer:
Average speed = 9.59 m/s
Explanation:
Given data:
Distance = 100 m
Time taken = 10.42 s
Average speed = ?
Solution:
Formula:
Average speed = distance covered / time taken
by putting values,
Average speed = 100 m / 10.42 s
Average speed = 9.59 m/s
