Which does NOT affect the speed of an object that is pushed

balanced forces do not affect the motion of the object. Unbalanced forces affect the motion and velocity of an object.

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.

we need the questions , i may then you.
