Do not enter the state of compounds such as solids (s), liquids (l) or gases (g).Parentheses ( ), square brackets and braces (curly brackets) =Fe.H2O for a water molecule or (NH4)2SO4 for ammonium sulfate. Indices should be entered as normal numbers after the appropriate elements or groups, e.g.

The formula of a substance should be entered using the upper case for the first character in the element’s name and the lower case for the second character (compare: Co – cobalt and CO – carbon monoxide).

The substances are separated by a plus sign (+). Reactants and products in a chemical reaction are separated by an equal sign (=).The method is modified for finding integer coefficients. Our chemical equation balancer calculator uses the Gauss-Jordan elimination algorithm for solving a system of linear equations. However, in cases where we are dealing with more complex reactions involving many compounds, it is preferable to balance the equations using more advanced algebraic methods based on solving a system of linear equations. Thus, we have the following coefficients: a=1, b=4, c=1, d=5Īs the result we have the following balanced equation:

Let’s solve the system by direct substitution and find the values of the remaining variables: To quickly solve this system of equations, we assign a numerical value to one of the variables. It is necessary to find such a solution that all the coefficients have the form of the smallest possible integers. This system has several solutions, since there are more variables than equations. It remains for us to solve the above system of linear equations in order to find the numerical values of the coefficients. As can be easily checked by substituting in the previous equations, this equality is a consequence of them, not an independent relation. Since the left and right sides must contain the same number of hydrogen atoms, we get: 2 b =3 c+ d. For example, on the left we have 2 b hydrogen atoms (2 in each H2O molecule), while on the right we have 3 c+ d hydrogen atoms (3 in each H3PO4 molecule and 1 in each HF molecule). Next, we equate the number of atoms of each element in the left and right sides of the equation.

Put a factor in front of the single carbon atom on the right side of the equation to balance it with the 2 carbons on the left side of the equation: So the first thing to do in our case is to balance the carbon.

If it is necessary to balance several elements, we first choose one that is part of only one molecule of reactants and one molecule of reaction products. Note that usually hydrogen and oxygen are part of several molecules at once, so it is better to balance them last. On the right side we have 1 carbon atom, 2 hydrogen atoms and 3 oxygen atoms: C=1, H=2, O=3.On the left side we have 2 carbon atoms, 6 hydrogen atoms and 2 oxygen atoms: C=2, H=6, O=2.Consider the subscripts next to each element to determine the total number of atoms. Let us first write down the number of atoms of each element for both sides of the equation. Relatively simple equations like this one can be balanced by inspection and directly fitting the stoichiometric coefficients. As we can see, atoms of only three chemical elements are involved in this reaction.
