Because certain chemicals can have adverse reactions in your body when mixed.
Yes
Not ALL reactions are chemicals. When chemicals reacte with other chemicals it is called as chemical reactions.
Because some reactions between chemicals can cause explosions, release toxic gases, etc.
Unless you know what chemicals you are mixing, and what kinds of chemical reactions they are going to have, you don't know what will happen when you mix chemicals. There are some chemicals which, when mixed, will release a very deadly poisonous gas. There are other chemicals which, when mixed, will explode or burst into flames. Even aside from that, chemicals in a science lab are there for some reason. Someone obtained those chemicals for the lab and intends to do something with them. They are not there to play around with at random.
Allergic reactions depend on a person's immune response and biological reactions. This means that all chemicals has the potential to trigger at least one person's allergic reaction.
Chemicals are often mixed in test tubes
it can cause a fire, explosion and dangerous chemical reactions
Mixing dangerous chemicals together can result in hazardous reactions that may release toxic gases, cause fires or explosions, or produce harmful byproducts. It is essential to follow proper handling and storage procedures for chemicals and never mix them unless you are trained to do so in a controlled environment.
Because some chemical reactions result in an exothermic or endothermic reaction in the products.
These are exothermic reactions.
a solution is two substance mixed together
