Chemical Reaction and The PH Scale

Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter.
A Chemical reaction is the outcome of two or more elements together results in the formation of a chemical bond between atoms and compound. Chemicals react together due to participating atoms. The reason why atoms react with each other is to reach a state in which their valence shell is filled. Reactions occur at different speeds, they have different rates of reaction. There are some things that must be considered in a chemical reaction. Kinetics is one of these things. Kinetics decides The speed of the reaction and what is happening on a molecular level. There are a few things that decide the course and speed of the reaction.
One thing about chemical reaction is that , there is now known that there are three types of chemical reactions. They are classified into three types: exoergic (exothermic), endoergic (endothermic), and aergic (athermic). In these cases, energy is supplied, but the different types of reactions initiate the energy differently.
First of all , Exoergic, or exothermic, reactions release energy during the reaction. Combustion is one of the major reactions that do this. The burning of wood, or any other fuel, gives off heat, and the burning of glucose in our bodies gives off both energy and heat. Secondly, Endoergic, or endothermic, reactions absorb energy during the reaction. The melting of an ice cube is an example of an endothermic reaction. And last, Aergic, or athermic, reactions neither give off nor absorb energy. There are very few cases in which this happens.
One example, of chemical reation is imagine you want to bake bread. You will need seperate and very different elements such as water, eggs, flour, and yeast. As you m...
