El radio de un átomo de hidrógeno es aproximadamente de 0.37 Å y el radio medio de la órbita terrestre alrededor del Sol es del orden de 1.5 x 108 km. Calcule la relación entre el radio promedio de la órbita terrestre y el radio del átomo de hidrógeno

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
