The answer is CHANGE.
hope this helped!
Answer:
See below
Explanation:
The equation shows Al / Cl = 2/3 or 3/2 Al = Cl
3/2(20) = 30 Cl atoms needed
The equation shows a one-to-one relationship between Al and AlCl3
produced so if you use 20 Al atoms you get 20 AlCl3 molecules
Answer:
A
Explanation:
it becomes a positive charge and fully filled
A theory is something that has been proven a few times, so yes it’s been consistent in science but not enough. A law is something multiple scientists have proven to be true multiple times, causing it to be a law.
Answer:
The answer is option 2.
Explanation:
Given that the formula to find kinetic energy is K.E = 1/2×m/v² where v represent the speed of an object. So if the speed increases, kinetic energy also increase.
Therefore, kinetic energy has the highest amount at 60 mph.
