The ChemicalEquationBalance is an elegant app that does exactly as its name suggest, balances chemical equations and more. Easy to use, easy to understand, simple and effective. It balances the chemical equations, including net ionic equations as well as redox reactions. To find a solution, it uses Gauss-Jordan elimination technique to find the coefficients. It shows procedure to find the solution step by step. It also displays the input matrix which after performing Gauss-Jordan elimination forms a solved matrix with coefficients. It also performs Stoichometry calculations (mole to mole, mole to gram, gram to mole, gram to gram conversion for each reactant and product combinations). It finds the limiting reagent involved in the chemical equation. The equations are beautifully presented in classical chemical equations form. it is also possible to share the solution. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. This is a perfect app if you are a student learning to balance chemical equations. There is also a Study page to help you with learning some important chemistry topics. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
