Now, we can move on to the problem-solving stuff.

Function to set up and solve Constraint Optimization Problem However, we store the coefficients as a negative number since this will make it easier when setting up our constraints.

Code SnippetДЇirst, we iterate over the lhsCompounds and store the result from chemparse as well as the unique elements.ДЄfter that we iterate over rhsCompounds, we do not need to store the unique elements again. We need to store the unique elements so we can form constraints for each and convert each reactant and product into a dictionary produced by chemparse. To get the compounds we can split by вЂњ+вЂќ and remove the trailing spaces. We can split by вЂ->вЂ™ to get the Left Hand Side and the Right Hande Side] Code Snippet The function will expect an input similar to the one below Zn + HCL -> ZnCl2 + H2 LetвЂ™s create a function to parse the equations. They are taken from the libraryвЂ™s documentation вЂњCH4вЂќ returns

pip3 install chemparseД«elow are a few examples of what chemparse returns. We will use the chemparse library to parse the reactants and products. Now, we can move on to generalizing this to support other equations as well. This problem can be set up using PuLP and solver using PuLPвЂ™s default solver. To summarize this is how our problem is setup Problem Setup The problem has no objective other than minimizing the coefficients, which means the objective is basically 0 (None). The Problem can be considered as a Minimizing Problem since we need to find the smallest coefficients that can balance the equation. For H: The number of Hydrogen Atoms in Reactant must equal to the number of Hydrogen Atoms in Products Constraint due toВ H.For Cl: The number of Chlorine Atoms in Reactant must equal to the number of Chlorine Atoms in Products Constraint due toВ Cl.For Zn: The number of Zinc Atoms in Reactant must equal to the number of Zinc Atoms in Products Constraint due toВ Zn.Each variable must be an integer greater than or equal to 1. X1, X2, X3, and X4 are the variable coefficients. The coefficient of each reactant/product can be thought of as a variable. LetвЂ™s consider the first equation we had looked at Example of an Unbalanced Equation So how can we use Constraint Optimization?

Eg: The below equation although doable manually will require quite a bit of trial and error. However, things get complicated as the number of elements increases and the number of reactants/products increases. The above equation was easy to solve and can be done manually. As a result, the equation is balanced and it no longer violates the law of conservation of mass. The number of atoms in the Products remains unchanged.

In the balanced equation, we are using 2 atoms of H and Cl in the reactants.

This does not respect the law of conservation of mass However, there is only a single atom of H and Cl in the Reactants.

In the unbalanced equations, there are 2 atoms of H and Cl in the Products.

In the above picture, you can notice the following Basically if you X grams of an element as a reactant, the product will also have X grams of that element in the Products (ideal conditions). How can we balance Chemical Equations using Constraint Optimization?Д«alancing a chemical equation essentially means respecting the conservation of mass and ensuring the same number of atoms of an element are present on the left-hand side (Reactants) and the right-hand side (Products).

calcium hydroxide + carbon dioxide = calcium carbonate + waterД®xamples of the chemical equations reagents (a complete equation will be suggested):.

PhCH 3 + KMnO 4 + H 2SO 4 = PhCOOH + K 2SO 4 + MnSO 4 + H 2O.

To enter an electron into a chemical equation use + H 2O.

Compare: Co - cobalt and CO - carbon monoxide

Always use the upper case for the first character in the element name and the lower case for the second character.Дћxamples: Fe, Au, Co, Br, C, O, N, F.
