Question
Introduction to Balancing Chemical Equations Learning Goal: To learn how to balance chemical equations. Chemical equations are written representations of chemical reactions. For example, a chemical equation can be written for the reaction of hydrogen gas (H₂) with oxygen gas (O₂). producing liquid water (H₂O): H₂(g) + O₂(g) H₂O(1) This chemical equation is unbalanced because the number of each type of atom is not equal for both sides of the chemical equation: H₂(g) + O₂(g) → 2 H atoms H₂O(1) 2 H atoms 20 atoms 10 atom To balance the equation, place coefficients in front of the reactants and/or products so that the number of each type of atom on each side of the arrow is equal. The coefficient indicates the number of moles of each substance present in the reaction. Part B ?= Starting with the unbalanced equation for the combustion of ethanol, C₂H5OH(1) + O₂ (8) CO₂ (g)+?H₂O(1) what coefficient should be placed in front of H₂O to balance the hydrogen atoms?
