Hydrogen can act as a reducing agent by reducing metal oxides to their corresponding metals.

Hydrogen peroxide (H2O2) can act as a reducing agent due to its ability to donate electrons.

Hydrochloric acid is commonly used for cleaning metal surfaces due to its ability to remove rust and scale.

Hydrogen is commonly used in fuel cells to produce electricity through a chemical reaction with oxygen.

Hydrogen is used in the hydrogenation process to convert unsaturated fats into saturated fats in the petroleum industry.

Sodium bicarbonate is commonly used as an antacid to relieve heartburn and indigestion by neutralizing stomach acid.

Copper can be extracted using various methods including electrolysis, roasting, and hydrometallurgy.

BF3 (boron trifluoride) is a Lewis acid because it can accept an electron pair.

Acids in aqueous solution can conduct electricity due to the presence of ions.

Acids are known for their sour taste, while bases are bitter and slippery.

Hydrogen gas (H2) acts as a reducing agent by donating electrons in redox reactions.

NH4Cl (ammonium chloride) is a salt formed from the strong acid HCl and the weak base NH3.

Hydrochloric acid (HCl) is a strong acid formed from hydrogen.

Sulfuric acid (H2SO4) is a strong acid that contains hydrogen.

Sodium hydroxide is a strong base that is often used in drain cleaners and other cleaning products.

CN- (cyanide) is a strong field ligand that causes large splitting of d-orbitals in transition metal complexes.

Sublimation is not a method used for extracting metals; it is a phase transition from solid to gas.

Hydrogen is not used in the direct synthesis of nitric acid; instead, it is primarily used in the production of ammonia and hydrogenation processes.

Cyanide (CN-) is a strong field ligand that causes greater splitting of d-orbitals in transition metal complexes.

Sodium reacts vigorously with water to produce hydrogen gas.

Aluminum is extracted from its ore, bauxite, using electrolytic reduction.

The Hall-Héroult process is used for the electrolytic reduction of aluminum oxide to produce aluminum.

Aluminum is extracted from its ore, bauxite, using electrolysis due to its high reactivity.

Alumina (Al2O3) is the primary source of aluminum, extracted from bauxite through the Bayer process.

Aluminum is extracted using electrolysis due to its high reactivity and the need for a large amount of energy to reduce it from its ore.

Gold is often found in its native state due to its low reactivity with other elements.

Sodium is highly reactive and easily oxidized compared to the other metals listed.

Copper is more likely to be reduced because it has a higher reduction potential compared to the other metals listed.

Iron is most susceptible to corrosion in the presence of moisture, leading to rust formation.

Aluminum commonly forms a +3 oxidation state in its compounds.
