That would be correct as stated.
Answer:

Explanation:
Hello.
In this case, since the neutralization of the acid requires equal number of moles of both acid and base:

Whereas we can express it in terms of concentrations and volumes:

Thus, we can compute the volume of sodium hydroxide (base) as follows:

Best regards.
So we look equation for the free Gibbs free energy (ΔG) which depends on entalpy (ΔH), temperature (T) and entropy (ΔS):
ΔG = ΔH - TΔS
ΔG is negative (-) because the water absorption on the silica gel surface is a spontaneous process.
ΔH is negative (-) because the water absorption on the silica gel surface is a exothermic process (it releases heat and if you want to desorb the water form the silica gen you need to add heat which is a endothermic process).
ΔS is negative (-) because the water is adsorbed, so from disorderly state you take the water molecules and put them in a orderly state and by doing that you decrease the entropy.
Answer:
4Amps. i can't see other questions clearly
Explanation:

I=V/R
I=120/30
I=4amps
Testable, that is always required for a hypothesis. Otherwise, how can you prove it?
