Answer:
Approximately .
Explanation:
If the concentration of ions in a solution is , the of that solution would be .
Note that the base of the logarithm in this calculation should . One way to be sure is to state the base explicitly. Using the change of base rule of logarithms:
.
In this question, it is implied that the concentration of in the given solution is , such that . Using the equations above:
.
The correct answer is making observations in his experiment.
In his cathode ray tube experiment J. J. Thomson proved that the cathode rays are indeed negatively charged particles. He then went on to calculate charge-to-mass ratio of the electron. J. J. Thomson’s pioneering work lest to the theory that the atomic structure is made up of charged particles.
Answer:
Gas(this is because we are only considering that there are 3 states of matter, while in reality there are 5.)
Explanation:
There are actually 4 states of matter excluding a 5th one that has just been discovered, but if we consider that there are only 3 states of matter then the particles move the fastest in gases. As the particles are the furthest apart.
