What type of chemical reaction is combustion? What are the products of a combustion reaction? Is combustion a chemical reaction? What is always true of a combustion reaction? What is enthalpy of combustion? How does a combustion reaction differ from other chemical reactions?
To recognize a combustion reaction, look for oxygen in the reactant side of the equation and the release of heat on the product side. Because it isn't a chemical product, heat isn't always shown. Sometimes the fuel molecule also contains oxygen. A common example is ethanol (grain alcohol)...

What are Combustion Reactions? - A combustion reaction is a chemical reaction which a fuel undergoes oxidation by reacting with an oxidising agent, resulting in the release of energy (usually in the form of heat).
Energy is an important physical quantity which signifies the capacity to do work. It cannot be created or destroyed but it can be interconverted from one form to another. Answer and Explanation: Learn more about this topic: Combustion Reaction | Definition, Equation & Examples ...
Hint :Combination, decomposition, single-displacement, double-displacement, and combustion are the five basic forms of chemical reactions. By examining the reactants and products of a reaction, we can categorise it into one of these groups.Complete Step By Step Answer...
Classify reactions assynthesis, decomposition, single replacement, double replacement, or combustion. What is the root word of reaction? reaction (n.) Modeled on French réaction, older Italian reattione, fromMedieval Latin reactionem (nominative reactio), a noun of action formed in Late Latin fro...
A. Reactant that provides oxygen for combustion. B. Product formed during combustion. C. Catalyst that speeds up the reaction. D. Inert gas that does not participate in the reaction. 相关知识点: 试题来源: 解析 A。在甲烷燃烧的反应中,氧气(O₂)是反应物,为燃烧提供氧。选项 B 它不是产物...
