What process is used to refine aluminum from its ore bauxite?
Murljashka [212]

Answer:

D. Smelting

Explanation:

Bauxite is the aluminum ore from which alumina, also known as aluminum oxide, Al₂O₃, is produced. Bauxite is extracted from the topsoil regions of some subtropical and tropical regions, and the Bayer process is primarily then used to produce alumina from the bauxite.

Aluminum is produced from the alumina by an aluminum smelting process known as the Hall—Heroult electrolytic process which involves the use of a carbon anode and direct current to produce aluminum by reducing the aluminum oxide

When the following equation is balanced, what is the coefficient for O2?
harkovskaia [24]

Answer:

3 is the coefficient of oxygen.

Explanation:

Chemical equation:

CH₃OH + O₂      →     CO₂ + H₂O

Balanced chemical equation:

2CH₃OH + 3O₂      →     2CO₂ + 4H₂O

The given reaction is combustion reaction. In this reaction methanol is burn in the presence of oxygen and produces carbon dioxide and water.

The balance equation show reaction also follow the law of conservation of mass.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
