Chapter 9.2, Problem 29SSC

Interpretation Introduction

Interpretation:

The four types of chemical reaction and their characteristics needs to be explained.

Concept introduction:

Chemical reaction is the process in which rearrangement of atoms of one or more substances occur to produce different substances. There are many evidences of a chemical reaction, such as, change of temperature, color change, formation of gas and solid etc.

Answer to Problem 29SSC

Four types of chemical reactions present, they are, synthesis, combustion, decomposition and displacement reaction.

Explanation of Solution

There are four types of chemical reactions, synthesis reaction, combustion reaction, decomposition reaction and replacement reaction.

Synthesis reaction is the reaction in which reaction of two or more substances takes place to obtain a single product.

Combustion reaction is the reaction in which combination of oxygen with a substance occurs in which release of energy occurs in the form of light and heat.

Decomposition reaction is the reaction in which breaking down of single compound into two or more new compounds takes place.

Replacement reactions are the reactions in which replacement of an element in a compound occurs by another element.
