8 0

Answer:

Answers are in the explanation

Explanation:

A bomb calorimeter is a <em>constant volume </em>calorimeter in which medition of change in temperature allows the medition of change in internal energy (ΔU) for chemical reactions or physical changes.

This ΔU can be converted in ΔH thus:

ΔH = ΔU + PV

That means that:

A bomb calorimeter is a piece of equipment designed to measure <em>delta H</em>

As there was said:

Reactions carried out in a bomb calorimeter occur at constant <em>volume</em>

To calculate the heat absorbed or released by a reaction carried out in a bomb calorimeter, we use the equation: <em>q = C * delta T</em>

Where C is the heat capacity of the calorimeter, delta T is the change in temperature and q is the heat produced in the chemical or physical process

I hope it helps!

The physical and chemical properties of a molecule depend on its structure. Here are two ball-and-stick models for two compounds
djyliett [7]

Answer:

Ethanol has covalent intramolecular bonds. Ethanol is polar. Ethanol has dispersion intermolecular forces. Dimethyl ether is polar. Dimethyl ether forms hydrogen bonds. Dimethyl ether has dispersion intermolecular forces.

Explanation:

Ethanol is not a carboxylic acid. It is an alcohol and it has covelent intramolecular bonds. It is polar and it also has dispersion intermolecular forces.

Dimethyl ether is also polar and it has forms hydrogen bonds. It also has dispersion intermolecular forces. Dimethyl ether does not have ionic intramolecular forces

Draw an electrolytic cell in which Mn2+ is reduced to Mn and Sn is oxidized to Sn2+. (Assume standard conditions).
babunello [35]

Answer:

-1.05 V

Explanation:

A detailed diagram of the setup as required in the question is shown in the image attached to this answer. The electrolytes chosen are SnCl2 for the anode half cell and MnCl2 for the cathode half cell. Tin rod and manganese rod are used as the anode and cathode materials respectively. Electrons flow from anode to cathode as indicated. The battery connected to the set up drives this non spontaneous electrolytic process.

Oxidation half equation;

Sn(s) ------> Sn^2+(aq) + 2e

Reduction half equation:

Mn^2+(aq) + 2e ----> Mn(s)

Cell voltage= E°cathode - E°anode

E°cathode= -1.19V

E°anode= -0.14 V

Cell voltage= -1.19 V - (-0.14V)

Cell voltage= -1.05 V
