Chemical Reactions and Chemical Quantities

These flashcards cover key concepts related to chemical reactions, particularly combustion reactions, alkali metal reactions, and halogen reactions as discussed in the lecture.

Combustion Reaction

A chemical reaction where a substance reacts with oxygen to produce oxygen-containing compounds and heat.

Hydrocarbon

Organic compounds consisting entirely of hydrogen and carbon; examples include methane (CH4), propane (C3H8), and butane (C4H10).

Methane (CH4)

A hydrocarbon that undergoes combustion to produce carbon dioxide (CO2), water (H2O), and energy.

Propane (C3H8)

A hydrocarbon commonly used for heating and cooking; burns to form carbon dioxide (CO2) and water (H2O).

Alkali Metals

Elements in Group 1 of the periodic table that react vigorously with nonmetals and water to form hydroxides.

Oxidation

A chemical reaction that involves the addition of oxygen or the removal of hydrogen; often occurs during combustion.

Metal Hydroxide

A compound formed when alkali metals react with water, resulting in a base and hydrogen gas.

Halogen Reaction

Reactions involving halogens that produce metal halides or hydrogen halides when they react with metals or nonmetals.

Interhalogen Compounds

Compounds formed when halogens react with each other.

Hydrogen Halide

Compounds formed when halogens react with hydrogen; examples include hydrochloric acid (HCl) and hydrobromic acid (HBr).
