Given the discoveries of electrons in 1897 by Thomson, Rutherford and other scientists decided that a positively charged particle must exist to center the electron to create equally neutral atoms. Thomson proposed the name 'positive rays'.
A. 8,330 --> 8.33 × 10^3
B. 83.3 --> 8.33 × 10^1
C. 0.00833 --> 8.33 × 10^-3
D. 0.0833 --> 8.33 × 10^-2
E. 83,330 --> 8.33 × 10^4
Hope this helps!
Answer:
same density
Explanation:
The amount of methanol is a quantitative characteristic, and by the other side the density of methanol is a qualitative characteristic. What I mean is that the amount of methanol is not related to the density; it would be the same density no matter how much methanol you have.
Answer:
Explanation:
This question tests for concentration after dilution of the solution. is added to 200ml of water.
The formula for concentration correlation is given as , where the latter relates to the final solution mix.
Therefore the concentration is 0.300M
Electrical generators.
Hope this is right.
