Answer:

La pregunta no es clara, asi que voy a dar una breve descripicion de la termodinamica y alguno de los fenomenos que estudia

La termodinámica es la rama de la física que estudia los sistemas en equilibrio termodinámico (es decir, aquellos sistemas que no pueden sufrir un cambio espontáneo). Particularmente, la termodinámica estudia los procesos de flujo de calor (lo podemos ver en su nombre, dinámica del calor) y se relacionan estos cambios de energía con el trabajo que es posible obtener.

Entonces, por ejemplo, la termodinámica estudia como el hielo puede cambiar de fase (a medida que aumenta su temperatura) y convertirse en agua líquida.

La termodinámica también estudia como funcionan máquinas de calor, como motores de pistones, y el trabajo que estos son capaces de realizar.

Como ejemplo final, con la termodinámica podemos estudiar cosas tan complejas como equilibrio entre distintas fases (por ejemplo, el porqué podemos tener agua y hielo en equilibrio termodinámico, un ejemplo de esto son las superficies de ríos que se congelan mientras la parte inferior sigue siendo líquida)

Esos son, entre muchísimos otros, 3 posibles efectos que suceden a nuestro alrededor, y son estudiados por la termodinámica.

Which formula equation shows a reversible reaction? 2 upper N a plus upper F subscript 2 right arrow 2 upper N a upper F. Upper
Tamiku [17]

Upper N upper H subscript 4 upper C l (s) right and left arrows stacked above each other upper N upper H subscript 3 (g) plus upper H upper C l (g)

Explanation:

The given equation is;

  NH₄Cl    ⇄      NH₃   +    HCl

This equation is clearly different from the other ones.

  • In the reactant going forward, there is a right and left arrows stacked above each other.
  • The symbol is  ⇄  and it is used to show reversibility of chemical reactions.

2.
katovenus [111]

Answer:

A. 6atm

Explanation:

Using pressure law equation:

P1/T1 = P2/T2

Where;

P1 = initial pressure (atm)

T1 = initial temperature (K)

P2 = final pressure (atm)

T2 = final temperature (K)

According to this question;

P1 = 3 atm

P2 = ?

T1 = 120K

T2 = 240K

Using P1/T1 = P2/T2

3/120 = P2/240

Cross multiply

240 × 3 = P2 × 120

720 = 120P2

P2 = 720/120

P2 = 6atm

What is the oh−concentration and ph in each solution? (a) 0.225 m koh, (b) 0.0015 m sr(oh)2?
shepuryov [24]
Q1)
We have been given the OH⁻ concentration, therefore we first need to find the pOH value and then the pH value.
pOH = -log [OH⁻]
pOH = -log (0.225 M)
pOH =  0.65
pH + pOH = 14
pH = 14 - 0.65 = 13.35

Q2)
pOH = -log[OH⁻]
pOH = -log (0.0015 M)
pOH = 2.82
pH + pOH = 14
pH = 14 - 2.82 
pH = 11.18
