Answer:

Answers are in the explanation

Explanation:

A bomb calorimeter is a constant volume 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 delta H

As there was said:

Reactions carried out in a bomb calorimeter occur at constant volume

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

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!

Consider four different samples: aqueous LiF, molten LiF, aqueous AgF, and molten AgF. Current run through each sample produces

meriva

Answer:

Molten LiF forms solid lithium

Aqueous AgF forms solid silver

Aqueous LiF forms hydrogen gas.

Explanation:

Aqueous solution of $LiF$ has water molecule, there will be competing will be two competing cations for reduction, while $Li^{+}(aq)$ and $H^{+}(aq)$ .However the reduction potential of $H^{+}(aq)$ is more than that of the $Li^{+}(aq)$ . Hence, $H^{+}(aq)$ reduced to hydrogen gas.

Molten $LiF$ has only solid form of $LiF$ and $Li^{+}(aq)$ reduced to form $Li$ solid.

An aqueous form of $AgF$ contains water molecules.there will be competing will be two competing cations for reduction, while $Ag^{3+}(aq)$ and $H^{+}(aq)$ .However the reduction potential of $Ag^{3+}(aq)$ is more than that of the $H^{+}(aq)$ . Hence, $Ag^{3+}(aq)$ reduced to solid silver.

Therefore, Molten LiF forms solid lithium

Aqueous AgF forms solid silver

Aqueous LiF forms hydrogen gas.
