Heat required : Q = 83500 J = 83.5 kJ

<h3>Further explanation</h3>

Given

mass ice = 250 g at 0°C

Required

The heat required

Solution

The heat to change the phase can be formulated :

Q = m.Lf (melting/freezing)

Lf=latent heat of fusion

Input the value :

Q = 250 g x 334 J/g

Q = 83500 J

The density of a block of wood with a volume of 50 cubic centimeters and a mass of 100 grams is?
german

2 g/cm³ is the density of the block of wood

Explanation:

To determine density of the block of wood we use the following formula:

density = mass / volume

density of the wood block = 100 g / 50 cm³

density of the wood block = 2 g/cm³

When considering the relationship among standard free energy change, equilibrium constants, and standard cell potential, the equ
DedPeter [7]

Answer:

ΔG° = - RTLnK is used to find the standard cell  potential given the equilibrium constant

Explanation:

for an ideal disolution:

⇒ ΔG = RT∑ni LnXi

∴ ΔG = ( μi - μi*)ni

∴ μ : chemical potential

∴ μ*: chem. potential of the pure component at T and P.

⇒ ΔG = μi - μi* = RT LnXi

for a equilibrium reaction:

⇒ ∑ νi*μi = 0

⇒ ΔGr = ΔG°+ RT Ln Kx = 0

⇒ ΔG° = - RT LnKx
