The most reactive element of this list is Chlorine, the next most reactive is bromine, and the least reactive is iodine.
All of these three elements are group 7 elements in the periodic table. It is known that the reactivity of group 7 elements decreases down the group. The most reactive element in this group is Flourine with reactivity decreasing down the group.
The reason for this decrease in reactivity is that as you go down the group, the distance between the positive nucleus that attracts valence electrons increases, decreasing the electrostatic attraction between the nucleus and the outer electrons. The other reason is that the electrons in lower energy levels closer to the nucleus repel and shield the electrons in the outermost shell or energy level of the atom.
Chlorine>Bromine>Iodine.
Answer:
100 times
Explanation:
Since inertia is directly proportional to the mass of an object, the higher the mass the higher the inertia. In this case, 6 Kg is 100 times heavier than 0.06 Kg to imply The bowling ball has 100 times more inertia than the tennis ball because it has 100 times more mass
Kinetic Energy:
Kinetic Energy is the energy of motion.
Mass:
Mass is the number of particles that a substance has
I think the correct graph would be
the THIRD GRAPH
Answer:
Δx = 3.99 m
Explanation:
To determine distance, use kinetic energy
will make it short and easy.
KE=1/2mv2 and KE=Δxmgμ
Set the equations equal to each other
1/2mv2=Δxmgμ (Note: The masses cancel
)
1/2v2=Δxgμ Solve for Δx
where g=9.8
Δx=v2/(2gμ) Δx = 25 / (2 * 9.8 * 0.32) Δx = 3.99 m
Please let me know if its correct, if not report it so we can correct it.
Answer:
Acceleration
Explanation:
Acceleration has units of length per time squared.
