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>
KCl2 (potassium dichloride) ?I’m not completely sure
Answer: Magnet
Explanation:Using a magnet is the best separating technique to be deployed in this case. The nails are easily picked out by just holding a magnet over the sandbox.
Atoms of Mg = mol * L
mol of Mg =
=
= 2 mol
∴ atoms of Mg = 2 mol * ( 6.02 x 10²³)
= 1.204 x 10²⁴
