EQUATION OF CHEMICAL REACTIONS
What is a chemical reaction ?????? A substance is said to undergo chemical changes, if the substance is transformed into a new substance of different properties of the substance of origin. Chemical Change is also called Chemical Reaction. What happens when chemical reactions take place ???????
There are so many chemical reactions happening in the world. His example is rusted iron, apples are peeled off his skin and left for a while will be blackened and many more examples dialam. Chemical reactions also occur in laboratories. Where the chemical reactions occurring in the laboratory are characterized by several features, such as sediment formation, gas formation, color change, or heat change.Here's a video guide to make it easier to understand the equalization of chemical reactions.

Why are there chemicals that can not react?
BalasHapusIn chemistry there are some reactions that can not be reinterpreted.
HapusFor example is a noble gas group that is difficult to react with other compounds.
The noble gas element is difficult to react with other elements because the octet precious electron structure of the octet (8) (except helium duplet) is the most stable structure so called inert gas.
What is the chemical reaction formula on rusted iron ?
BalasHapusIn corrosion events, the metal undergoes oxidation, while oxygen (air) is reduced. The metal rust is generally an oxide or carbonate. The chemical rust formula is Fe2O3.nH2O, a solid brown-red substance.
HapusWhat the meaning of gas formation?
BalasHapusThe gas formation is defined as the ratio of gas volume in reservoir conditions to the volume of gas under surface conditions.
HapusWhat reactions are classified in chemical reactions?
BalasHapusBy knowing some properties or types of reactions, we can understand the chemical reactions more easily. Generally, chemical reactions are classified by type as follows:
Hapus1) Reaction of merging
2) Decomposition reaction
3) Reaction of change (single exchange reaction)
4) Metathesis reaction (multiple exchange reaction)
