The U. S. Navy and the British Navy are doing joint training exercises in the Mediterranean. Both navies are practicing firing missiles at a target, but their firing velocities don't match. US missiles travel at 640 miles per hour. The British need to match the velocity of the US missiles, but their speed is measured in meters per second. What must the British velocity be to match the US missile velocity at 640 mph? Begin by converting miles to kilometers. (1.0 mile = 1.6 km)

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)
