How Does Stoichiometry Apply In My Life

Introduction

Stoichiometry is inclined within the many branches of chemistry, as it deals with the relative amount of chemical change between the reactant and the product of compounds and elements. In simpler words, Stoichiometry is used for us to predict how much mass of a substance is required to be used in order to be involved in a chemical reaction.

As a student myself, I find Stoichiometry the hardest within all the past third quarter grading lessons as I can’t comprehend complex knowledge at a fast rate, thus I needed time to understand all the concepts regarding Stoichiometry.

Also, like the other students out there, I also question myself, “Where will I even use this in my life? What’s the application of Stoichiometry in daily

My best example for you is air-bag designs in cars because these require stoichiometric precisions. Even the production of your favorite banana ice cream can be considered as an application of Stoichiometry! See, Stoichiometry can be observed everywhere  it just takes the right eye to see it.

Stoichiometry was actually widely used in the Army. How? Well back in the Army, soldiers had food squeezed into packets. And how were they going to eat that? Stoichiometry dealt with that answer. Again, how? Well, the food squeezed into packets were to combine with water, and after that, just like magic, they have now a meal served upon them.

We all have a lot of questions regarding Stoichiometry, and so do I. This module is created to help fellow students that are having a hard time with Stoichiometry. I have broken down complicated concepts into simpler one, because like any other student, I don’t like complicated, and complex
