Which of the following is true about the action-reaction forces encountered in Newton’s third law A. always cancel each other out

B always act on different objects

C are always the same as normal and frictional forces

D None of the above

Explanation:

D)None of the above

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.
