Chemistry

  Examples of Chemical Reactions in Everyday Life Examples of Chemical Reactions In Everyday Life - Chemistry   is a branch of science that deals with the study of the composition, structure, properties, reaction and behavior of substances.  Therefore, chemistry is called central science. This is the essence of our daily lives and occurs in the foods we eat, the air we breathe, the water we drink, are all the result of the chemical reaction process. In fact, osmosis like love, hatred, also driven by chemical reactions.  To better understand the almost chemical reactions around us, we have provided everyday examples in two parts.  First, an example of a chemical reaction in our body and two examples of chemical reactions that exist outside our body or occur around us. Chemical Reactions In The Body Chemical reactions play an important role in our survival, and living without chemicals can not even be imagined.  They participate in the main functi...

Dialogue of teachers and students In class that morning Teacher: "good morning children" All students: "morning sir" Teacher: "today we will learn about acid and alkaline substances, who knows what is acid and alkaline?" Ani: "I pack, I think it's acid that has a sour taste and alkaline compounds that have a bitter taste." Teacher: "yes very good, there is one acid that does not have a sour taste that is CHCOOH that has no taste. The acid-base theory proposed by some scientists, one of them is the theory of Arrhenius which says acid is a property which can interconnect ion ion hydrogen (H +) when dissolved in air, whereas a base is a property which can be released hydroxide ion (OH-) when dissolved in air The acid-base reaction (neutralizing reaction) is a H2O-forming reaction of H + and OH- Another theory is proposed by the Bronsted-Lowry theory which states that acids can give protons (H +) to other compounds, whereas a ...

Cause And Efect O f C hemichal R eaction A. Understanding               Chemical changes are changes in substances that produce new substances. For example: the paper before being burned has properties different from the paper before being burned. Examples of chemical changes are rice rot, stale milk, stale vegetables, rotting eggs, salted eggs, rusted iron, etc. B. The characteristics of chemical changes 1. The formation of new types of substances 2. Substances that change can not return to their original shape 3. Followed by changes in chemical properties through chemical reactions During chemical mass changes the substance before the reaction is equal to the mass of the substance after the reaction. C. The causes of chemical changes 1. Can occur due to combustion   One of the chemical changes that we often see in everyday life is combustion events. Do you know what burning is? Burn...
