What kind of chemical bond exists between two nitrogen atoms to form nitrogen gas? Is this a strong or weak bond? When a chemical bond is formed, is energy absorbed or released?

pure covalent bond ( inter atomic bond)

Explanation:

pure covalent exists between atoms of the same kind..two nitrogen atoms have the same electronegativity values hence cancel out making it a pure or non polar covalent bond

Ans: E = 1.9 *10⁻⁴⁹ J

Given:

Frequency of photon, ν = 2.9 *10⁻¹⁶ Hz

planck's constant, h = 6.63*10⁻³⁴ Js

To determine:

The energy (E) of photon

Explanation:

Energy is related to the frequency by:

E = hν

   = 6.63*10⁻³⁴ Js * 2.9 *10⁻¹⁶ s-1

   = 1.9 *10⁻⁴⁹ J
