today is exams so i need the best ans. ✔

Answer 1

•the total linear momentum of a system of particles not acted upon by external forces is constant in magnitude and direction irrespective of any reactions among the parts of the system.
• Conservation of momentum is a fundamental law of physics which states that the momentum of a system is constant if there are no external forcesacting on the system. It is embodied in Newton's first law (the law of inertia)

Answer 2

$\huge\mathfrak{hiiiii}$

here's your answer ⏩⏩

✴the principle that the total linear or angular momentum in any isolated system is constant, provided that no external force is applied

✴According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

✴ The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.

hope it helps u ✌✌
