Nikolay [14]

Answer:

Black hole most massive and white dwarf least massive should be correct. It really just depends on the original size of the star and it's gravitational pull pre death.

Explanation:

Just what I learned over time. I would still do more research on the subject though.

At what temperature teq do the forward and reverse corrosion reactions occur in equilibrium?

Vedmedyk [2.9K]

Standard Gibb's free energy at 298K and 5975K is 3.16×10⁶J and -3.83×10⁵J respectively, and temperature at equilibrium state is 5362.3 K.

<h3>What is the standard Gibb's free energy?</h3>

The complete question is in the brainly link at the end. We can say that;

Standard Gibb's free energy of any reaction is gotten from the formula;

∆G° = ∆H° - T∆S°

where;

∆G° is change in free energy

∆H° is change in enthalpy = 3352 kJ = 3352 × 10³J

∆S° is change in entropy = 625.1 J/K

T is absolute temperature = 298 K

Plugging in the relevant values into the gibbs energy equation gives;

∆G° = (3352 × 10³) - (298 × 625.1)

∆G° = 3.16 × 10⁶J

Gibb's free energy at temperature of 5,975 K is;

∆G° = (3,352 × 10³) - (5,975 × 625.1)

∆G° = -3.83 × 10⁵J

At the equilibrium state, the value of Gibb's free energy is zero. Thus we can calculate the temperature as;

0 = (3352 × 10³)J - (T × 625.1 J/K)

Solving for T gives;

T = 5362.3 K

sammy [17]

Enumerated rights are specifically listed in the Constitution. Unenumerated rights are protected by the Ninth Amendment.

The Ninth Amendment clearly indicates that the list of rights listed in the Constitution is not exhaustive, and that the rights established in other sources remain valid regardless of whether they are mentioned in the Constitution.

Thus, it is understood that there are two types of rights: the enumerated rights, that are those explicitly mentioned in the Constitution, and on the other hand, the non-enumerated rights, that are those not named in the constitution but protected by the Ninth Amendment.
