I think the answer you're looking for is a "Chemical Reaction". For instance, combining Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) will cause a Chemical Reaction resulting in salt water (NaCl + H20).
No. A chemical reaction is not alive.
A chemical reaction is a reaction in which elements have their chemical and/or physical properties altered by the end of the reaction.
heat is produced, light is produced, gas is produced, the chemicals change color.

Yes. They can. The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. If you take either baking soda or baking powder, and you add them to vinegar they both form bubbles in a chemical reaction.
the four components of fire are heat, fuel, oxygen and the sustaining chemical reaction
- forming a homogeneous solution- forming a precipitate by chemical reaction- sedimentation of an insoluble phase, without chemical reaction

Four factors are:- temperature- pressure- catalysts- stirring
Heat, Fuel, Oxygen and Chemical Chain Reaction
The four different types of chemical weathering are hydration, oxidation, carbonic acid action and hydrolysis. Chemical weathering is a chemical reaction that erodes certain things such as building materials and rocks.
