How does the path of a river change over time? (describe the process)

All rivers naturally change their path over time, but this one forms meanders

Explanation:

When you stand next to a river, its path doesn't seem to move.

All rivers naturally change their path over time, but this one forms meanders  at an especially fast rate, due to the speed of the water, the amount of sediment in it, and the surrounding landscape.

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.

all eukaryotic cell have mitochondria : )
