Answer #1

Answer: A single displacement reaction has an element in elemental form on both the reactant and the product side of the arrow. This because, in this reaction one element is oxidised and other is reduced during displacement.

A combustion reactions always involves oxygen gas as a reactant because oxygen helps in combustion.

First two option are wrong because in decomposition reaction one compound is broken into two or more compound.

During synthesis reaction two or more compound combine to generate desired product.

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
