When a bullet is fired from a gun, what is true about the momentum? The gun has more momentum than the bullet, so the momentum is not conserved. The bullet and gun have equal momenta in opposite directions, so the system’s momentum is conserved. The bullet has more momentum than the gun, so the momentum is not conserved. The bullet and the gun have equal momenta in the same direction, so the system’s momentum is conserved.

A.to show that most molecules exist in pairs B.to show that most compounds exist in pairs C.to show that atoms are conserved in chemical reactions D,to show that atoms are created in chemical reactions

Answer: The correct answer is Option D. Explanation: Lewis dot structures are the structures which represent the valance electrons of an element forming a compound. The electrons are represented as the dots. In a compound, the bonded electrons are represented as a bond and lone pair of electrons are represented …
