To use the app of chem calculator, the user simply enters the unbalanced equation into the chemical balancer app, and the app adjusts the coefficients of the reactants and products to solve. Enter the value 1 in the bottom right cell I8, and fill column K with zeros and 1 as shown. Following are the steps to Balance Chemical Equations using this app: - An chemical equation solver uses algorithms to balance chemical reactions. For the products, column G chromium pentoxide has -5 O and -1 Cr, column H potassium sulphate has -2 K, -1 S and -4 O, and column I water has -2 H and -1 O. Thus in column D, hydrogen peroxide has 2 H and 2 O atoms in column E potassium dichromate has 2 K, 7 O and 2 Cr and in column F sulphuric acid has 2 H, 4 O and 1 S. The table is filled with the numbers of each type of atom in the reactant and product compounds, reactants being positive and products negative. In column J are entered each of the atomic species in the reaction, ie H,K,O,Cr & S ( their order doesn't matter ) and x at the end. Next is a table in block D3:K8 which will contain the input matrix, with the coefficient headings a-f at the top of the block. Column C is for the calculated results and can be left empty to begin with. The reactants and products are entered in column A and their coefficients a,b,c, d,e, & f in column B.

The next step is to set up a table in the spreadsheet as shown in Table 1. Just enter in each molecule name and it will give the right numbers of each required to balance the equation. a H2O2 + b K2Cr2O7 + c H2SO4 → d CrO5 + e K2SO4 + f H2O To begin with, we write out the reactant and product species formulae and apply algebraic coefficients to each: Reactants ProductsĮg.
