3. How much heat is required to raise the temperature of 179g of acetic acid, CH3COOH, from 250C
IgorLugansk [536]

Answer:

Q = 1252.82kJ

Explanation:

Mass = 179g

Initial temperature (T1) = 25°C = (25+273.15)K = 298.15K

Final temperature (T2) = 82.70°C = (82.70 + 273.15)K = 335.85K

Specific heat capacity (c) = 121.3J/g.K

Heat energy (Q) = mc∇T

M = mass of the substance

Q = heat energy

c = specific heat capacity of the substance

∇T = change in temperature of the substance = T2 - T1

Q = mc∇T

Q = 179 × 121.3 × (355.85 - 298.15)

Q = 21712.7 × 57.7

Q = 1,252,822.79

Q = 1252.82kJ

The heat energy required to heat 179g of acetic acid from 25°C to 82.70°C is 1252.82kJ

The result of the procedure is that the copper strip should go through oxidation.

<h3>How to explain the procedure?</h3>

The copper strip should be considered as the anode and the nail should be considered as the cathode.

The anode is the electrode of an electrochemical cell at which oxidation occurs. The anode should be + while the cathode should be negative. Both should be placed in the tank that should be filled with the electrolyte solution.
