Chemistry: Intermediate
Count moles, predict shapes, balance redox equations: worked out step by step.
What you'll learn
- ✦Use significant figures correctly and calculate a limiting reagent and the mass or volume of product it allows
- ✦Explain the Bohr model's limits and describe an electron's orbital using its four quantum numbers
- ✦Write the electronic configuration of an element up to Z = 36 using the Aufbau, Pauli exclusion and Hund's rules
- ✦Use the modern periodic law to place an element and predict a periodic trend between two elements
- ✦Predict a molecule's shape using VSEPR theory and name the hybridization of its central atom
- ✦Calculate the enthalpy change of a reaction and decide if a process is spontaneous using entropy and Gibbs energy
- ✦Write the expression for an equilibrium constant and predict which way a reaction shifts when conditions change
- ✦Balance a redox equation using the oxidation-number or ion-electron method
- ✦Name a simple organic compound using IUPAC rules and predict whether a hydrocarbon reacts by substitution or addition
