In this lesson, students will learn about the symbols in chemical equations and how to determine if they are balanced.
Students will be able to read and interpret chemical equations.
Students will answer questions to review the periodic table. They will also look at equations, such as 3a + 4b = 25 and y = mx + b, and write down some common symbols they see. They will talk about how math symbols, like = and +, are used in chemical equations.
Introduce chemical equations, reactants, and products. Students will find the reactants and products in 2HCl → H₂ + Cl₂. Discuss the common symbols seen in chemical equations, including, chemical symbols, plus (+), and yield (→). Students will recall some chemical symbols prompted in the lesson.
Next, explain the purpose of the coefficient, and the difference between a coefficient and a subscript. Explain that products and reactants are balanced in chemical equations. Students will determine whether the equation 2H₂ + N₂ → 2NH₃ is balanced.
Students will respond to ten true/false and multiple-choice questions.
Students will recall what they learned in the lesson and complete an exit slip.
