There are many ways of knowing when a chemical reaction is taking place:
- Precipitate Forms
- Changes in properties such as color, texture, luster and hardness.
- Gas and bubbles may be released
- Change in temperature- Due to the releasing or gaining of energy.
-Endothermic Reactions take place when in a chemical reaction, the substance gains or absorbs energy.
Observe evidence in chemical reactions!
In this video you can observe how iron reacts with oxygen when electrons are passed through it. The different concentrations of oxygen make the reaction highly react.
In this video you can observe the five major types of chemical reactions plus examples. Learn about synthesis, decomposition, single and double replacement etc.
In this video you can observe how by mixing water, light, food dye, salt crystals and mineral serpentine, you end up with an amazing result!
