Five different types of evidence that a chemical reaction has occurred include the formation of a precipitate, color change, evolution of gas, – Examples of physical changes include changes in size, shape, or state of matter. Color Change A chemical reaction may be indicated when a substance changes color without adding dye or paint. The most frequently mentioned examples include rusting iron, burning wood, cooking an egg, and mixing baking soda with vinegar. 2. Rust forms on a hammer that has been left outside to long. The document outlines evidence of chemical reactions, including gas production, temperature changes, color changes, precipitate formation, and light or odor Types Of Chemical Reactions Explained With Real-Life Examples · 1.
