Answer:
In the 5th cycle rinse, the residual concentration of the solution is < 0.00001M
Explanation:
In each rinse cycle, the dilution that you are doing of the solution is from 1.00mL to 10.00mL, that is a dilution of 10
In the first rinse the concentration must be of 0.9M 10 = 0.09M
2nd = 0.009M
3rd = 0.0009M
4th = 0.00009M
5th = 0.000009M →
<h3>In the 5th cycle rinse, the residual concentration of the solution is < 0.00001M</h3>
Answer:

Answer:
The correct answer is - Positive charge occupies a very small volume in the atom.
Explanation:
Ernest Rutherford's experiments exhibited the presence of the nuclear core: a small region with the greater part of the mass of the atom and the positive charge.
Rutherford's gold foil analyze gave three conclusions:
- the particle is generally vacant space
- in it is a little, thick core or dense nucleus
- the core is positively charged.
