3 Fundamental Laws of Chemistry
Three foundational chemistry laws—conservation of mass, definite proportions, and multiple proportions—set the rules for how matter behaves in...
S12E2 - Rate Laws: Differential Rate Laws and the Integrated Rate Law
Rate laws are the key link between what’s happening chemically and how fast it happens: they express how a reaction rate depends on reactant...
SI Units in Chemistry
Chemistry measurements rely on the SI system because units make numbers meaningful and comparable across labs worldwide. A measurement isn’t just a...
S15E2 - How do Buffer Solutions Resist Changes in pH?
A buffer’s pH stays nearly steady when a strong base is added because the added OH⁻ is quickly “quenched” by reacting with the buffer’s weak acid,...
S18E3 - Coordination Compounds, Ligands, and Complex Ions of Transition Metals
Coordination compounds are built around a charged “complex ion” made from a transition metal ion plus attached ligands, with additional counterions...
S6E1 - Thermochemistry and the Nature of Energy. Potential vs Kinetic Energy, & the Transfer of Heat
Energy is defined as the capacity to do work or produce heat, and it obeys a strict rule: the total energy of the universe is conserved—never created...
S2E1 - Three Fundamental Laws of Chemistry; Law of Conservation of Mass; Dalton's Atomic Theory
Chemistry’s three “fundamental laws” are introduced as the backbone for balancing reactions and predicting how elements combine—then tied directly to...
S8E2 - Electronegativity, Dipole Moments, and Bond Polarity
Whether a bond is ionic or covalent—and whether it makes a molecule polar—comes down to electronegativity differences between the bonded atoms....
S7E1 - Electromagnetic Radiation (EMR), the Electromagnetic Spectrum, & Energy/Frequency/Wavelength
Electromagnetic radiation (EMR)—from gamma rays to radio waves—differs only in energy, frequency, and wavelength, and those differences determine...
S12E3 - How to Determine the Form of the Rate Law: The Method of Initial Rates
Determining the form of a reaction’s rate law becomes a matter of experiment rather than guesswork: the method of initial rates extracts the reaction...
S11E1 - Molarity, Molality, Mass Percent, and Mole Fraction
Solution chemistry starts with a simple need: mixtures can be uniform, but their “strength” must be measured precisely for calculations. When a...
S1E3 - Types of Errors in Measurement, and Accuracy vs. Precision
Measurement errors come in two distinct flavors: random errors, which scatter results in both directions, and systematic errors, which push...
