Answer:
Entropy change of ice changing to water at 0°C is equal to 57.1 J/K
Explanation:
When a substance undergoes a phase change, it occurs at constant temperature.
The entropy change Δs, is given by the formula below;
Δs = q/T
where q is the quantity of heat absorbed or evolved in Joules and T is temperature in Kelvin at which the phase change occur
From the given data, T = 0°C = 273.15 K, q = 15.6 KJ = 15600 J
Δs = 15600 J / 273.15 K
Δs = 57.111 J/K
Therefore, entropy change of ice changing to water at 0°C is equal to 57.1 J/K
Answer:
yeesss. I am sooooo ssaaaddddd
Answer:
Explanation:
Molecular equation for the reaction:
HI(aq) + KOH(aq) --> KI(aq) + H2O(l)
Ionic equation
K+(aq) + OH-(aq) + H+(aq) + I-(aq) --> K+(aq) + I-(aq) + H2O(l)
Net ionic equation:
H+(aq) + OH-(aq) --> H2O(l)
