Answer:
cools as it rises, then sinks back down
Explanation:
The movement of air is a convection current. Convection currents occur when warm air rises, cools down, and sinks due to gained density, replacing the warm air closer to the ground, creating a cycle.
The correct name for the N3- ion is a nitride ion.
The most condensed state of matter is solid
The greatest molar amount of metal product is obtained from silver (1) nitrate.
Let us determine the mass of metal obtained in each case.
For La^3+;
La^3+ + 3e ----> La
1 mole of La is deposited by 3F
x moles of La is deposited by 10 F
x = 1 × 10/3
x = 3.33 moles
For Zn^2+;
1 mole Zn^2+ is deposited by 2F
x moles of Zn^2+ is deposited by 10 F
x = 5 F
For Ag^+
1 mole of Ag^+ is deposited by 1 F
x moles of Ag^+ is deposited by 10 F
x = 10 moles
For Ba^2+;
1 mole of Ba^2+ is deposited by 2 F
x moles of Ba^2+ is deposited by 10 F
x = 5 moles

The element that Davis discovered will be potassium.
<h3>What is potash?</h3>
Potash is the general name used to refer to salts that contain potassium in a water-soluble form.
In order words, potassium is the major cation in potash. Thus, if any potash salt is made to separate into its component ions, potassium metal will be formed as deposition.
By applying an electric charge to potash and realizing metallic globules, it means the metallic globules are largely potassium.
