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

Answer:
Carbon tetrachloride would be 2.2 fold heavier than water
Explanation:
Carbon tetrachloride (2.20g/mL) is denser than water (1.00g/mL)
Answer: Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. ... The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.

As the reaction speed involves the overcoming of the activation energy (due to a required amount of kinetic energy between the particles). When temperature is increased it will provide more energy for the movement of the particles to gain more kinetic energy meaning the rate at which the particles interact increase
