# 2021-05-23 Labii Integrated 4 New Chemical-related Widgets

To facilitate the chemical drawing and stoichiometry, [Labii ELN & LIMS](https://www.labii.com/) just released a minor version (v5.05) to integrates a few more chemical-related widgets in [Electronic Lab Notebook (ELN) ](https://www.labii.com/electronic-lab-notebook)and Laboratory Information Management System (LIMS).

## [**Chemical Equation Balancer**](https://docs.labii.com/widgets/chemistry/chemical-reaction#chemical-equation-balancer)

Chemical Equation is a form of describing a chemical reaction in which the name of each chemical substance will be replaced by its chemical symbol. Labii has developed a widget to perform the chemical equation balance and calculate the reaction stoichiometry.
