Instructions

To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

• Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
• Ionic charges are not yet supported and will be ignored.
• Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
• Compound states [like (s) (aq) or (g)] are not required.
• You can use parenthesis () or brackets [].

Examples

• Hexane = Benzene + Dihydrogen
• C6H14 + (9.5O2) = CO2 + H2O

Balance C6H14 = C6H6 + H2 Using the Algebraic Method

To balance the equation C6H14 = C6H6 + H2 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 represent the unknown coefficients. a C₆H₁₄ = b C₆H₆ + c H₂

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 = 6b + 0c H: 14a = 6b + 2c 

Step 3: Solve For All Variables

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

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

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

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. C₆H₁₄ = C₆H₆ + 4 H₂

Since there is an equal number of each element in the reactants and products of C6H14 = C6H6 + 4H2, the equation is balanced.

Balance C6H14 = C6H6 + H2 Using Inspection

The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in C6H14 = C6H6 + H2 must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a time until both sides are equal and the chemical equation is balanced.

Step 1: Count the number of each element on the left and right hand sides

Step 2: Multiply coefficients for compounds to balance out each element

H is not balanced. Add 3 molecules of H₂ to the product (right-hand) side to balance Hydrogen:
C₆H₁₄ = C₆H₆ + 4 H₂

Step 3: Verify that the equation is balanced

Since there are an equal number of atoms of each element on both sides, the equation is balanced.

Hexane – C₆H₁₄

Hexane is an unbranched hydrocarbon with the formula C₆H₁₄.

• Hexane is a nonpolar molecule with a weak intermolecular interactions occur between the molecules of pure liquid hydrocarbons.
• It is a highly volatile, flammable toxic chemical which is a by-product made from crude oil.
• Hexane isomers are to a great extent lifeless, and are every now and again utilized as an organic solvent since they are very non-polar

Other names – Amyl Carbinol, 1-Hexanol, Hexyl alcohol, 1-Hydroxyhexane

    Frequently Asked Questions

    What is hexane used for?

    Hexanes are used for the manufacture of clothing, leather goods, and roofing glues. They are also used to extract cooking oils from seeds (such as canola oil or soy oil), to clean and degrease a variety of products, and in textile manufacturing.

    Is hexane a good solvent?

    When you are trying to dissolve a nonpolar compound, hexane is a strong solvent; but, if you were trying to use hexane to dissolve a polar compound it would be very unsuccessful. With a polar compound, water would be a safer option than hexane, because water is polar and can interact more readily with the polar compound.

    Why hexane is flammable?

    N-Hexane is a crude oil-producing compound. Pure n-Hexane is a liquid with a slightly unpleasant odour. It is extremely flammable, and can be explosive in its vapours. The key application for n-Hexane-containing solvents is to extract vegetable oils from crops such as soybeans.

    Does hexane evaporate?

    Pure n-hexane is a liquid with a slightly unpleasant odour. This evaporates very quickly into the sun, and just partially dissolves in water. N-Hexane is extremely flammable and can have volatile vapours.

    Why is hexane used for extraction?

    N-hexane is used as a solvent in solvent extraction for its attributes such as quick recovery, non-polar existence, low vaporisation latent heat (330 kJ / kg), and high solvent selectivity. Enzyme processing has significant potential to extract oil in the oilseed industry.
