I think it’s a not for sure
If the electrolyte contains chemical species that will be reduced at the cathode or oxidized at the anode (or both), that means chemical change. The electrolyte can form one or more compounds or ionic species that weren't there before.
<span> A given species could form at one </span>electrode<span> but diffuse back over to the other electrode where it promptly breaks back up into its reactants. </span>
<span>If the electrolyte does not participate in any reaction(s), it will just act as a conductor of electricity. The same goes for the electrodes. Some materials will react but will not produce anything obvious (gases, precipitates, or color changes). Others will not react at all under the specific combinations of voltage and current. </span>
Answer:
47.36mL
Explanation:
Using Boyles law equation, which states that:
P1V1 = P2V2
Where;
V1 = initial volume (mL)
V2 = final volume (mL)
P1 = initial pressure (atm)
P2 = final pressure (atm)
Based on the provided information, V1 = 25.3mL, P1 = 152 kPa, V2 = ?, P2 = 0.804atm
First, we need to convert 152kPa to atm by dividing by 101
1kPa = 0.0099atm
152kPa = 1.505atm
P1V1 = P2V2
1.505 × 25.3 = 0.804 × V2
38.08 = 0.804V2
V2 = 38.08/0.804
V2 = 47.36mL

Answer:
C. Water passes into the salt solution, dehydrating bacterial cells and making them harmless.
Explanation:
The salt solution is hypertonic to the bacterial cells and as such, water molecules will move from the bacterial cells into the salt solution, dehydrating the cells and rendering them harmless.
Option A is also true but it is irrelevant to the question asked. Option B and D are wrong.
The correct option is C.
