Ba(HCO3)2 + Na2CO3 = BaCO3 + NaHCO3 - Chemical Equation Balancer

To balance the equation Ba(HCO3)2 + Na2CO3 = BaCO3 + NaHCO3 using the algebraic method step-by-step, you must have experience solving systems of linear equations. The most common methods are substitution/elimination and linear algebra, but any similar method will work.

Step 1: Label Each Compound With a Variable

Label each compound (reactant or product) in the equation with a variable to lớn represent the unknown coefficients.

Step 2: Create a System of Equations

Create an equation for each element (Ba, H, C, O, Na) where each term represents the number of atoms of the element in each reactant or product.

Ba:	1a	+	0b	=	1c	+	0d
H:	2a	+	0b	=	0c	+	1d
C:	2a	+	1b	=	1c	+	1d
O:	6a	+	3b	=	3c	+	3d
Na:	0a	+	2b	=	0c	+	1d

Step 3: Solve For All Variables

Use substitution, Gaussian elimination, or a calculator to lớn solve for each variable.

1a - 1c = 0
2a - 1d = 0
2a + 1b - 1c - 1d = 0
6a + 3b - 3c - 3d = 0
2b - 1d = 0

Use your graphing calculator's rref() function (or an online rref calculator) to lớn convert the following matrix into reduced row-echelon-form:

[ 2	 0	 0	-1	0]
[ 2	 1	-1	-1	0]
[ 6	 3	-3	-3	0]
[ 0	 2	 0	-1	0]

The resulting matrix can be used to lớn determine the coefficients. In the case of a single solution, the last column of the matrix will contain the coefficients.

Simplify the result to lớn get the lowest, whole integer values.
