Which experiment would you perform to determine if the total momentum is conserved in a collision? Collide two objects of known masses, and measure the velocity of one object before the collision and the other object after the collision.
Drop two objects from the same height and measure how long it takes them to reach the ground.
Apply the same amount of force to two objects of different mass, and compare the change in their velocities.

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
