The teacher prepares 2.50 liters (L) of a salt solution for a class experiment. How many quarts (qt) are in 2.50L? ( 1 quart = 0
jek_recluse [69]
Quarts are a measurement for liquids.
1 quart is equivalent to 0.943 litres
The volume of the solution is 2.50 L
Since 0.943 L = 1 quart
Then 2.50 L = 1 quart/0.943 L x 2.50 L
Volume = 2.65 quarts
Volume in quarts is 2.65 qt

Answer:

Am I the bad guy for killing my fish, let me explain?

Explanation:

The fish said a bad word that was incredibly inappropriate, so then I told him to never say that again. He responds with, "No, I CAN SAY WHATEVER I WANT." After that I told him to not yell at me and then I killed him, remember he's a fish (GoldFISH).

Considere la siguiente reacción: H, (g) +1, (a) = 2 HI (9). K, para la reacción es 54.3 a 430°C. Si se coloca H, 0.00623M, 0.004
bearhunter [10]

Answer:

[HI] = 0.0255M

[H₂] = 0.00466M

[I₂] = 0.00257M

Explanation:

Para la reacción:

H₂(g) + I₂(g) ⇄ 2HI(g)

La constante de equilibrio, K, se define como:

54.3 = [HI]² / [H₂] [I₂]

Donde cada concentración [] será la concentración en equilibrio para cada especie

Para saber la dirección del equilibrio definiremos Q como:

Q = [HI]² / [H₂] [I₂]

Donde las concentraciones [] serán las concentraciones actuales de cada gas

Reemplazando:

Q = [0.0224M]² / [0.00623M] [0.00414M]

Q = 19.5

Como Q<K, la reacción se desplazará hacia la derecha produciendo más [HI]. Así, las concentraciones en equilibrio serán:

[HI] = 0.0224M +2X

[H₂] = 0.00623M - X

[I₂] = 0.00414 - X

54.3 = [0.0224M +2X]² / [0.00623M - X] [0.00414M - X]

54.3 = 0.00050176 + 0.0896 X + 4 X² / 0.0000257922 - 0.01037 X + X²

0.00140052 - 0.563091 X + 54.3 X² =  0.00050176 + 0.0896 X + 4 X²

0.00089876 - 0.652691 X + 50.3 X² = 0

Resolviendo la ecuación cuadrática:

X = 0.001566M → Solución verdadera

X = 0.01141M → Falsa solución. Produciría concentraciones negativas

Reemplazando:

[HI] = 0.0224M +2*0.001566M

[H₂] = 0.00623M - 0.001566M

[I₂] = 0.00414 - 0.001566M

[HI] = 0.0255M

[H₂] = 0.00466M

[I₂] = 0.00257M

Siendo estas últimas, las concentraciones de las especies luego de alcanzar el equilibrio.
