Answer:
Procedure (2)
Explanation:
Assume the dialyses come to equilibrium in the allotted times.
Procedure (1)
If you are dialyzing 5 mL of sample against 4 L of water, the concentration of NaCl will be decreased by a factor of

Procedure (2)
For the first dialysis, the factor is

After a second dialysis, the original concentration of NaCl will be reduced by a factor of

Procedure (2) is more efficient by a factor of

<h2>The required option is "a triple covalent bond."</h2>
Explanation:
- Coordinate bonds are formed by sharing of electrons by only one of the atoms participating in the bond formation.
- Coordinate covalent bonds are formed in the molecules like CO in which coordinate bond is formed between carbon and oxygen as well as sharing of lone pair present on the oxygen atom.
- Covalent bonds are formed by sharing of electrons from both the atoms participating in the bond formation.
- If two atoms from the same element share three pairs of electrons each forming a bond there will be the formation of a triple covalent bond.
- Therefore, the bond is a triple covalent bond.
A thermal insulator because it would keep the heat in
Answer:
3.75 * 10^14
Explanation:
(3.0 * 10^17) / 800nm = 3.75 * 10^14hz ( have to have 17 and not 8 because its in nanometers)
