How do we know when a chemical reaction has happened? Well, there are a few things we can tell off, have you ever noticed those rotten leaves by the sidewalk? Yeah, they have overcome a chemical reaction themselves. Here is how you could tell if a chemical reaction happened:
- Colour Change:
2. Bubbles Form--> Produces a gas
3.Temperature Change
4.Luminescent-glows after mixing chemicals
So lastly, if you ever see anything like this happen, then you know the object of water(whatever), has over gone a chemical reaction.
