Textbook Question

What coefficients must be placed in the following blanks so that all atoms are accounted for in the products?C6H12O6→_C2H6O+_CO2a. 2; 1b. 3; 1c. 1; 3d. 2; 2

Verified step by step guidance

Identify the number of each type of atom in the reactant C6H12O6: 6 carbon (C), 12 hydrogen (H), and 6 oxygen (O) atoms.

Set up the equation with variables for the coefficients: C6H12O6 → xC2H6O + yCO2.

Balance the carbon atoms: 6 carbons on the left require 2x + y = 6 on the right.

Balance the hydrogen atoms: 12 hydrogens on the left require 6x = 12 on the right.

Balance the oxygen atoms: 6 oxygens on the left require x + 2y = 6 on the right.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Balancing Chemical Equations

Balancing chemical equations involves ensuring that the number of atoms for each element is the same on both sides of the equation. This is crucial for obeying the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Coefficients are used to adjust the quantities of reactants and products to achieve this balance.

Stoichiometry

Stoichiometry is the calculation of reactants and products in chemical reactions based on their molar ratios. It allows chemists to predict the amounts of substances consumed and produced in a reaction. Understanding stoichiometry is essential for determining the correct coefficients needed to balance a chemical equation.

Molecular Formulas

A molecular formula represents the number and type of atoms in a molecule. In the given equation, C6H12O6 (glucose) breaks down into C2H6O (ethanol) and CO2 (carbon dioxide). Recognizing the molecular formulas helps in identifying the number of each type of atom present, which is necessary for balancing the equation correctly.
