When a batter at a baseball game hits a ball, why do you see the bat hit the ball before you hear the bat hit the ball? Light travels faster than sound.
Sound travels faster than light.
Sound and light travel at the same speed.

Explanation:The interference of two sound sources of slightly different frequencies produces beats. When watching a baseball game, we often hear the bat hitting the ball after we actually see the hit. Why? We hear the bat hitting the ball before after we actually see the hit because light travels faster than sound.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
