2.00 g of an unknown volatile liquid was placed in a flask with a total volume of 265.0 mL. The cover of the flask has only a pi

Response:

Ethanol serves as a reducing agent.

The lowest integer coefficient for in the balanced equation is 4

Clarification:

A redox reaction, or oxidation-reduction reaction, is defined as one in which oxidation and reduction processes occur simultaneously.

Oxidation is the process whereby a substance loses electrons, resulting in an increase in oxidation state. In contrast, reduction entails a substance gaining electrons, leading to a decrease in oxidation state.

Reducing agents enable other substances to undergo reduction while becoming oxidized themselves.

Conversely, oxidizing agents facilitate other substances' oxidation while being reduced in the process.

For the chemical reaction in question, the half-reaction would be:

Oxidation:

Reduction:

To balance the oxygen atoms on both sides

For oxidation:

For reduction:

Then balance the hydrogen atoms on both sides.

• For oxidation:

For reduction:

Lastly, balance the charge.

• For oxidation: For reduction:

To balance the electrons, multiply the oxidation reaction by 5 and the reduction by 4 before combining both equations for a balanced redox reaction.

Oxidation:

• Reduction:

The finalized balanced chemical equation in acidic conditions will be:

In this redox process, ethanol acts as the reducing agent while the permanganate ion serves as the oxidizing agent.

Answer:

The heat capacity of the calorimeter is = 54.4

Explanation:

Given the data

Heat supplied Q = 4.168 KJ = 4168 J

Mass of water = 75.40 gm

Change in temperature = ΔT = 35.82 - 24.58 = 11.24 °C

From the conditions provided

Q = ΔT + ΔT

Plugging all values into the above equation yields

4168 = 75.70 × 4.18 × 11.24 +   × 11.24

611.37 =   × 11.24

= 54.4

This represents the heat capacity of the calorimeter.
