I’ve made this Equation Balancer with the introductory chemistry student in mind. I hope it will be used as a way for them to check their work quickly and easily but I highly doubt it. Its a rather simple program thus it requires a bit of precision in its input. It recognizes elements only as starting with capital letters and knows compounds are separated by ‘+’ or ‘=’. (In absence of a arrow key I’ve used the ‘=’ key as a way to denote one side of the equation from the other). For those who are interested, the widget works by creating a homogeneous matrix containing the number of an element in each compound and then solves it for the coefficients.
