📖 1. Reactants and Products

🔑 Key Concepts & Definitions

• Reactants: substances that start a chemical reaction and are consumed during the process. They are the initial materials that undergo change.
• Products: substances formed as a result of a chemical reaction. They are the new materials produced after the reaction occurs.
• Chemical Reaction: a process where reactants are transformed into products, involving the breaking and forming of chemical bonds.

📝 Essential Points

• Reactants are always listed on the left side of a chemical equation.
• Products are always listed on the right side of a chemical equation.
• Identifying reactants and products is essential to understanding the direction and outcome of a reaction.

💡 Key Takeaway

Focusing on the starting materials (reactants) and the resulting substances (products) helps in understanding the flow and outcome of a chemical reaction.

📖 2. Arrow in Equations

🔑 Key Concepts & Definitions

• Arrow Symbol (→): indicates the direction of the chemical reaction from reactants to products. It shows the transformation process occurring during the reaction.

• Word Equation: a chemical equation written using the names of substances instead of chemical formulas. It describes the reactants and products in words.
