The electron configuration for sulfur, which has 16 electrons, is 1s² 2s² 2p⁶ 3s² 3p⁴.
Sodium chloride (NaCl) is an ionic compound, consisting of positively charged sodium ions and negatively charged chloride ions.
In KMnO₄, potassium has an oxidation state of +1 and oxygen has an oxidation state of -2. To balance the charges, manganese must have an oxidation state of +7.
Hydrogen bonds are the strongest type of intermolecular force compared to London dispersion forces and dipole-dipole interactions.
As you move from left to right across a period, elements become less metallic and more non-metallic in character.
Catalysts increase the rate of a reaction by lowering the activation energy and are not consumed during the reaction.
Methane (CH₄) has a tetrahedral molecular geometry, with four hydrogen atoms symmetrically distributed around the central carbon atom.
Ammonia (NH₃) exhibits hydrogen bonding due to the presence of a highly electronegative nitrogen atom bonded to hydrogen atoms.
The given equation represents a synthesis reaction, where two or more reactants combine to form a single product.
Fluorine has the highest electronegativity of all elements, meaning it has a strong ability to attract electrons in a chemical bond.
HCl is a strong acid that dissociates completely in water. The pH is calculated as -log[H⁺], so for a 0.01 M solution, pH = -log(0.01) = 2.
