Balancing Chemical Equations – Answer Key Balance the equations below: 1) 1 N2 + 3 H2 Æ 2 NH3 2) 2 KClO3 Æ 2 KCl + 3 O2 3) 2 NaCl + 1 F2 Æ 2 NaF + 1 Cl2 4) 2 H2 + 1 O2 Æ 2 H2O 5) 1 Pb(OH)2 + 2 HCl Æ 2 H2O + 1 PbCl2 6) 2 AlBr3 + 3 K2SO4 Æ 6 KBr + 1 Al2(SO4)3 7) 1 CH4 + 2 O2 Æ 1 CO2 + 2 H2O 8) 1 C3H8 + 5 O2 Æ 3 CO2 + 4 H2O 9) 2 C8H In other words, in a chemical reaction, what goes into the reaction must come out of the reaction. Using this knowledge and some bookkeeping skills, all unbalanced chemical equations can be balanced. Learning Objective • Learn the steps to balancing a chemical equation. Success Criteria • Demonstrate the ability to balance a chemical reaction. Chemical equations do not come already balanced. This must be done before the equation can be used in a chemically meaningful way. All chemical calculations to come must be done with a balanced equation. A balanced equation has equal numbers of each type of atom on each side of the equation. The Law of Conservation of Mass is the rationale for. KEY Chemistry: Balancing Chemical Equations Directions: First, balance each of the chemical equations below. Then, classify each reaction as synthesis, decomposition, single-replacement, or double-replacement. Sep 25, · Chemical equations must be balanced when studying chemistry. By understanding this process, we can comprehend the mechanics of reactions and how substances change into forms. The mass is conserved by ensuring equal numbers of atoms for each element on both sides of the equation. Writing and Balancing Equations Worksheet STO.1 Balance a chemical equation. STO.2 Identify the parts of a chemical equation. RXN.1 Describe a chemical reaction using words and symbolic equations.
