The entropy of a system can be calculated by the ratio of the total heat in the system and the temperature. Entropy is a measure used in thermodynamics to approximate the degree of disorder in a system. From the equation for entropy, we can calculate the enthalpy as follows:
S = H / T
109.0 J / mol K = H / 373.15 K
H = 40673.35 J / mol
False. The number of neutrons can be more or less than the number of protons.
Hydrogen-3 with scientific name Tritium often undergoes beta decay.
Answer:
Explanation:
Hello!
In this case, in a dilution process, water is added to a solute in order to decrease its concentration but increase the volume of the solution. It means that if we have 20.0 mL of a 12.0-M solution of HCl and we want a 0.500-M solution, we need to apply the following formula considering that the moles remain unchanged:
Thus, solving for the final volume is:
So plugging in the values we obtain:
Now, since the initial volume of acid was 20.0 mL and the final volume is 480 mL, the added volume of distilled water is:
Best regards!
The answer would be: <span>dependent on the number of particles
If you see the ideal gas formula you know that volume is directly related to the number of particles.
Closed container volume could influence the pressure that will change the volume but the question seems to talk about open container. If the container is not closed, then the volume of container won't have any effect.
Mass is related to the number of particles, but not directly related to volume so this option is a bit ambiguous.</span>
