On May 6, 1937, the airship (blimp) Hindenburg exploded in midair just seconds before completing its transatlantic voyage. Onboard the blimp had been 210,000 cubic meters of hydrogen gas. Since that time, airships have used helium gas rather than hydrogen gas to keep them aloft. Explain why in terms of valence electrons. PLEASE HELP WILL GIVE BRAINLIEST

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
