Chemistry: Equation Solver

Check chemical equation coefficients, look up stored reactions and find element properties with Chemistry. Keep the tools you use for homework and revision together: an equation balancer, molar mass calculator, periodic table and solution calculators. Balance chemical equations Enter the reactants and products to calculate balancing coefficients. For example, H2 + O2 → H2O becomes 2H2 + O2 → 2H2O. Find reaction equations Search the built-in reaction database by chemical formula to find matching equations. Results come from the stored reaction catalog. Calculate molar mass and composition Enter a compound formula to calculate its molar mass and the percentage by mass of each element. Explore the periodic table Tap an element to view its atomic number, atomic mass, electron configuration, electronegativity and other properties. Work with chemical solutions Calculate amounts for preparing solutions or diluting a stock solution to a target concentration. Look up chemistry reference tables Check the metal reactivity series and solubility table while studying displacement and precipitation reactions. Use core tools offline The equation balancer, built-in reaction search, periodic table and calculators work offline. Online content and ads need an internet connection. For students reviewing chemical equations, formulas and basic chemistry. Use the tools to check your work alongside your course materials.
