Light of certain energy shines on a metal and causes
electrons to be emitted. Based on the
research of Albert Einstein, the change that would most likely result in
stopping the emission of electrons from this metal is to coat the metal.
Answer:
14 ml of water
Explanation:
To find the volume you need to dilute the concentration of a solution, you should use the formula C1 x V1 = C2 x V2 in which:
C1 = initial concentration ( in this case 60 %)
V1 = initial volume ( in this case 70 ml)
C2 = Final concentration ( you want to dilute until 50 %)
V2 = final volume ( the variable you want to search)
So you need to:
1.- Isolate the variable you want to find: V2 = (C1 x V1) / C2
2.- Substitute data: V2 = (60% x 70 ml) /50 %
3.- You do the math, in this case is 84 ml.
4.- Remember that you have a initial volume of 70 ml, so the difference (84 ml - 70 ml = 14 ml) is the volume you need to add to dilute your solution.
False, it states that matter can be nether created nor destroyed
Answer:
An atom is the basic building block of matter. Anything that has a mass-- in other words, anything that occupies space--is composed of atoms.
