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

one of the following products at the cathode: solid lithium, solid silver, or hydrogen gas. Match each sample to its cathodic product. Drag the appropriate items to their respective bins.

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) andH^{+}(aq).However the reduction potential of H^{+}(aq) is  more than that of the Li^{+}(aq) . Hence, H^{+}(aq) reduced to hydrogen gas.

MoltenLiF  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) andH^{+}(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.

scZoUnD [109]

Answer:

The final volume is 990.8 L

Explanation:

Let calculate the moles of gas in the first situation:

P . V = n . R . T

1.20 atm . 2.90 L = n . 0.082 . 293K

(1.20 atm . 2.90 L) / (0.082 . 293K) = 0.145 moles

This are the same moles in the second situation:

P . V = n . R . T

0.003atm . V = 0.145 moles . 0.082 . 250K

V = (0.145 moles . 0.082 . 250K) / 0.003atm

V = 990.8 L

bearhunter [10]
Following three <span>things when applied could make the reaction to occur more quickly;

1) Increasing Temperature:
                                          Increase in temperature increases the Kinetic energy of molecules. This results in increase in the velocity and rate of collisions between reactants. Hence, greater the number of collisions between reactants per time greater will be the probability of formation of product per unit time.

2) Grinding Calcite:
                              Grinding of Calcium carbonate results in the increase of surface area of calcite. So greater the surface area greater is the exposure of Calcium carbonate to HCl molecules, hence the rate of formation of product increases.

3) Using Catalyst:
                            Very important. Catalyst when used decreases the activation energy and increase the rate of reaction by following methods.

                       a) Providing new pathway

                       b) weakening the bonds

                       c) providing surface area

                       d) holding up the reactant close to each other.</span>

zubka84 [21]

Answer:

Velocity, because it has both magnitude and direction.  

Step-by-step explanation:

Velocity is the rate at which an object changes position in a specific direction. It has both magnitude and direction.

The family is travelling south at 105 km/h. This is an example of velocity, because it has magnitude (105 km/h) and direction (south).
