Carbon Dioxide (CO2) is primarily responsible for the greenhouse effect, trapping heat in the atmosphere.

Alkali metals are found in Group 1 of the periodic table.

Halogens are located in Group 17 of the periodic table.

Noble gases are found in Group 18 of the periodic table.

Deuterium is the isotope of hydrogen with one neutron, denoted as H-2.

Protium is the most abundant isotope of hydrogen.

[Co(NH3)3Cl3] can exhibit geometrical isomerism due to the presence of different ligands in a square planar geometry.

The complex [Cr(en)3]3+ exhibits optical isomerism due to its chiral nature.

Ethylenediamine (en) is a bidentate ligand as it can form two bonds with the metal ion.

[Ni(CO)4] is diamagnetic because all electrons are paired in the presence of the strong field ligand CO.

[Co(NH3)6]3+ has unpaired electrons and is therefore paramagnetic.

AlCl3 contains aluminum, which is a p-block element.

In water (H2O), hydrogen has an oxidation state of +1.

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

CN- is a strong field ligand and causes large splitting of d-orbitals.

Hydrogen peroxide (H2O2) is a strong oxidizing agent.

Hydrogen gas (H2) is a strong reducing agent as it can donate electrons to other substances.

EDTA (ethylenediaminetetraacetic acid) is a well-known chelating agent.

SiO2 is formed from Silicon, which is a p-block element.

NaCl is formed by sodium, which is an s-block element.

Sodium reacts with water to form sodium hydroxide (NaOH) and hydrogen gas.

Iron is used as a catalyst in the Haber process for the synthesis of ammonia from nitrogen and hydrogen.

Sodium borohydride (NaBH4) is commonly used as a reducing agent.

Scandium has the highest atomic radius among the given d-block elements.

Mercury (Hg) is the only metal that is liquid at room temperature.

Tin can form a stable +4 oxidation state.
