Solid: vibrating at fixed position, because they have a strong force of attraction
Liquid: molecules sliding over each other, because they have a weaker force of attraction than solids
Gas: molecules moving freely at random directions, because they almost have no force of attraction
T<span>he name of the compound that goes with the chemical formula of MgCl2 is D. magnesium chloride.
Mg is magnesium, and Cl is chlorine, and when it has 2 atoms, it become chloride.
Fluorite is F2, which is why A is incorrect, and B and C are incorrect because manganese is Mn, and molybdenum is Mo.

0.035 mol CF₄ x 4 mols F/ 1 mol CF₄ = 0.14 mols F
0.14 mols F x 6.022x10²³/ 1 mol F= 8.43x10²² atoms
answer: 8.4×10²² atoms of F
maybe try this im not 100% sure though
Answer:
Cl⁻ is the reducing agent.
Explanation:
The redox reaction is as follow:
MnO₂ + 4H⁺ + 2Cl⁻ → Mn²⁺ + 2H₂O + Cl₂
One should know the following terms,
Reducing agent:
An atom or element which tends to lose electron during a chemical reaction and get itself oxidized. In above reaction Cl⁻ is reducing agent as it carries a negative charge (means it has one extra electron) on the reactant side while, it has zero oxidation state on the product side. It means going from -1 to 0 the Cl lost one electron hence, it is an reducing agent according to definition.
Oxidizing Agent:
On the other hand oxidizing agent is an element or compound which tends to accepts electron(s) and get itself reduced. In above reaction Mn has an oxidation state of +4 on reactant side and after gaining electron from Cl it has changed to +2 on the product side. Hence, it has reduced but has oxidized the Cl atom so it is an oxidizing agent according to definition.
Answer:
The mixture of cryolite and aluminum oxide has a lower melting point than pure aluminum oxide. This means a lower amount of energy is required to establish effective conditions for electrolysis and thus makes it more cost effective.
