Abstract

This study discusses the equalization of chemical reactions using a system of linear equations with the Gaussian and Gauss-Jordan elimination. The results show that there is a contradiction in the existing methods for balancing chemical reactions. This study also aims to criticize several studies that say that the equalization of the reaction coefficient can use a system of linear equations. In this paper, the chemical equations were balanced by representing the chemical equation into systems of linear equations. Particularly, the Gauss and Gauss-Jordan elimination methods were used to solve the mathematical problem with this method, it was possible to handle any chemical reaction with given reactants and products.

Highlights

  • Balancing of the chemical equation is one of the initial subjects taught in most preliminary chemistry courses (Hamid, 2019)

  • A large number of research articles have been written on this topic for last two decades. It draws much attention of chemists who feel very difficult in the case of balancing typical chemical reaction equations (Hari Krishna et al, 2020)

  • Balancing chemical reactions is an amazing subject matter for mathematics and chemistry students who want to see the power of linear algebra as a scientific discipline

Summary

Introduction

Balancing of the chemical equation is one of the initial subjects taught in most preliminary chemistry courses (Hamid, 2019). A large number of research articles have been written on this topic for last two decades It draws much attention of chemists who feel very difficult in the case of balancing typical chemical reaction equations (Hari Krishna et al, 2020). Balancing chemical reactions is an amazing subject matter for mathematics and chemistry students who want to see the power of linear algebra as a scientific discipline. Mass balance of chemical reactions is one of the most highly studied topics in chemical education (Risteski, 2012). This topic always draws the attention of students and teachers, but it is never a finished product. Johar et al / International Journal of Global Operations Research, Vol 1, No 4, pp. 130-135, 2020
