An 11.2 gram block of ice melts at 0'c. what is the change in entropy (in j/k) associated with this process? (the heat of fusion for water ah fus = 6.010 kj/mol.) j/k

ΔS = 1.37 × 10⁻² kJ/K

Explanation:

The change in entropy (ΔS) for the melting process can be calculated using the following expression.

ΔS = Q/T   [1]

where,

Q is the heat absorbed by the block of ice

T is the absolute temperature (in this case 0°C = 273.15K)

Q can be calculated like:

Q = ΔHfus . n = ΔHfus . m / M

where,

ΔHfus is the enthalpy of fusion for water

n is the number of moles

m is the mass

M is the molar mass

Then,

We can replace this value in [1].

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
