Chemistry
Tap the periodic table to build any formula. Get the molar mass, the name, the products, the balanced equation and the stoichiometry, with every step worked out the way your instructor writes it.
iPhone and Android apps: App Store and Google Play links are coming soon.
What's inside
Everything for the course, in one app.
Learn
53 short lessons that follow a two-semester general chemistry course, with practice that checks each step.
A periodic table that calculates
Molar mass, percent composition, and empirical and molecular formulas update as you tap.
Names and formulas
Ionic compounds, molecules, acids and hydrates, named and written correctly.
Predict and balance
Products, balanced and net ionic equations, and particle pictures of what is happening.
Stoichiometry
Grams to moles, limiting reactant and percent yield, laid out step by step.
Shapes and structure
Lewis structures, 3D VSEPR shapes and polarity you can turn and explore.
Search 14,659 compounds
Look up a compound by name, or a whole reaction like “baking soda + vinegar”, even without a connection.
For instructors
Build a problem set and share it as a link or QR code. Every student gets the same problems and a score they can send back to you.
Three levels
Start with Intro. Go as far as your course does.
IntroIncluded
Guided lessons, molar mass, names, reactions, stoichiometry, unit conversions, significant figures and practice problems.
General
The full two-semester course: gases, solutions, thermochemistry, kinetics, equilibrium, acids and bases, electrochemistry, nuclear and organic naming, plus a lab companion and chapter quizzes.
Professional
Buffer recipes with temperature and ionic-strength corrections, statistics and error propagation, and advanced sections in every tool.
