Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity.

El pH de una solución acuosa 10^-14 M de ácido acético, a 25°C, es igual a, teniendo en cuenta que Ke = 1.76x10^-5
frez [133]

Answer:

pH=14

Explanation:

Hola!

En este caso, consideramos que la disociación de ácido acético ocurre:

CH_3COOH\rightarrow CH_3COO^-+H^+

Así, mediante la solución del equilibrio ácido, podemos calcular la concentración de iones hidronio que posteriormente sirven para calcular el pH de la solución, por tal razón, debemos calcular el equilibrio dada la constante de equilibrio y por medio de la ley de acción de masas en términos del cambio x como cualquier problema de equilibrio:

Ke=\frac{CH_3COO^-][H^+]}{[CH_3COOH]}\\\\1.76x10^{-5}=\frac{x*x}{1x10^{-14}M-x}

Resolviendo para x, tenemos x=0.999x10^{-14}

Así, la concentración de hidrógeno es igual a x, por lo que el pH:

pH=-log([H^+])=-log(0.999x10^{-14})\\\\pH=14

Dicho valor tiene sentido desde que la concentración de hidrógeno es casi despreciable, por lo que se puede asumir que tiende a ser básica.

Saludos!

Assume the enthalpy of water at 30° C to be 1446 kJ while its mass is 8 kg. The average specific heat capacity of is 4.2 kJ/kg.K
vlada-n [284]

Answer:

enthalpy of water at 88^{0}\textrm{C} is 3394.8 kJ

Explanation:

Mass does not change with change in temperature .

Hence change in enthalpy (\Delta H) during increase in temperature from 30^{0}\textrm{C} to 88^{0}\textrm{C} is-

\Delta H=m\times c\times \Delta T

where m is mass of water, c is specific heat capacity of water and \Delta T is change in temperature.

Here, m = 8 kg, c = 4.2 kJ/(kg.K), \Delta T = (88-30) K = 58 K

So, \Delta H=8kg\times 4.2 kJ/(kg.K)\times 58 K = 1948.8 kJ

So, enthalpy of water at 88^{0}\textrm{C} = enthalpy of water at 30^{0}\textrm{C} + \Delta H = (1446 + 1948.8) kJ = 3394.8 kJ
