The Law of Conservation of Momentum states:
The total momentum before a collision is equal to the total momentum after a collision.
The total momentum before a collision is greater than the total momentum after a collision.
The total momentum before a collision is less than the total momentum after a collision.
The total momentum before a collision is not related to the total momentum after a collision.

An egg gets dropped from a height of 0.1 meters and cracks. A second egg gets dropped from the same height but this time it lands on a glass of water and does not break. In terms of impulse.
1st egg experienced more impulse
2nd egg experienced more impulse
both experienced the same impulse
