QuestionAnswer
reaction of a substance with oxygen to form an oxide with heat and light (fire); also burning combustion
the result (new substance) from a chemical reaction; product has different chemical and physical properties from the reactant(s) product
the original substance in a chemical reaction; either disappears or diminishes reactant
The following is an example of which type of reaction? CH3OH + O2 → CO2 + 2H2O + heat combustion
If a substance is completely consumed (it has a "limit") in a chemical reaction, what is that substance? limiting reactant
This reaction uses all of the energy up in the reaction ("End"s the energy) endothermic Reaction
