Complete the statements about the law of conservation of momentum. The law of conservation of momentum states that the total momentum of interacting objects does not
. This means the total momentum
a collision or explosion is equal to the total momentum
a collision or explosion.

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
