c6h6 +h2

To balance the equation C6H6 + H2 = C6H12 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 tướng represent the unknown coefficients.

a C6H6 + b H2 = c C6H12

Step 2: Create a System of Equations

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

C:	6a	+	0b	=	6c
H:	6a	+	2b	=	12c

Step 3: Solve For All Variables

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

  • 6a - 6c = 0
  • 6a + 2b - 12c = 0

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

[ 6	 2	-12	0]

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

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

  • a = 1 (C6H6)
  • b = 3 (H2)
  • c = 1 (C6H12)

Step 4: Substitute Coefficients and Verify Result

Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced.

C6H6 + 3 H2 = C6H12

Reactants Products

Since there is an equal number of each element in the reactants and products of C6H6 + 3H2 = C6H12, the equation is balanced.
