Want this question answered?
Momentum is always conserved. But if you want to verify, calculate the vector sum p = mv of both objects before the collision, and then calculate the vector sum p = mv of both objects after the collision. Your two vectors should be exactly equal.
because when it is bouncing, has more momentum than when it doesn't
Energy, if collision is rigid, total momentum is a constant also.
Linear momentum is mass times velocity. For a single point object, momentum is conserved, because the object will continue to move at a constant velocity. Nor will its mass change either. For a group of objects, too: When momentum is transferred, for example during a collision, any momentum lost by one object is gained by another. The total momentum remains constant.
Momentum of an object is its own property but it can be transferred by that object to any other object during their collision ( elastic or inelastic ) so as to conserve the total momentum of the system as demonstrated by the law of conservation of momentum. One of the examples of the transferring of momentum is the transfer of momentum and incident energy from photons of x rays to the loosely bound electrons in graphite target in Compton effect.
momentum
well i know momentum remains same before and after collision... But what about the period during which collision takes place?

The affect of force on the object during collision is described by a quantity called momentum. It is defined as p = mv where = p is momentum, m = mass of the object and v is velocity.

During a chemical reaction matter is neither created nor destroyed
In this context "conserved" means the total kinetic energy of all the objects is the same after the collision as before the collision. Note, the TOTAL is the same but the individual kinetic energies of each object may be different before and after. When two or more objects are about to collide they have a certain total kinetic energy. It is common that during the collision some of the kinetic energy is transformed into heat. So after the collision the total kinetic energy is less then before the collision. This is a non-elastic collision. There are some collisions, however, in which none of the kinetic energy is changed to heat. These are called ELASTIC collisions. So the total kinetic energy doesn't change, or is "conserved". There is another possible non-elastic collision. If during the collision there is an explosion, then its possible for the objects to have a larger total kinetic energy after the collision as they aquire some of the explosive energy. Finally note, that in all collisions the TOTAL vector momentum is the same just before and just after the collision. So in a collision momentum is always conserved.
Matter can not be created nor destroyed during any process, so no matter can not be destroyed during a chemical change.
There is no "energy during momentum". A moving object has both non-zero momentum, and non-zero kinetic energy.
