Chemical changes are taking place in almost everything that is going on. Chemical properties are determined by the reaction of a substance with other substances. Chemical changes are found in cheese making and at other jobs. When chemical changes take place some of the chemicals that were there may evaporate or turn into different chemicals. Some examples of chemical changes are combinations with acids and bases, reactions with oxygen and other active gases, and the reactions of the substance with other compounds. The chemical change of acids and bases are used when you are trying to remove warts. When your trying to kill someone with lethal gases you are using the oxygen and other active gases chemical change. The chemical change of substance and other compounds is used when your making the delightful treat of pudding. Chemical reactions are found in other ways but these are the most common occurrences.
Chemical change results in the production of new substances. Two types of substances which are very important in everyday life ar
Chemical changes between oxygen and other active gases can be harmful but also helpful in some ways. When oxygen and gases combine they turn into a different gas and that gas can be carbon dioxide, a useful gas, or carbon monoxide, a deadly gas. There are other gases but these are the ones we here about most. Another gas made is methane. Methane producing bacteria could have a profound effect on the atmosphere of the early Earth, producing strong absorption in mid-infrared at a wave number of 1300 cm. This is very harmful to earth. When factories release there smoke into the atmosphere it mixes with the oxygen and produces smog. Smog is not good for all of us to breath and makes it hard for us to see in the early hours of the morning. So for all the people who live in tight little compacted cities, they produce a lot of smog and they produce so much smog it comes into other states.
For the chemical reaction in a substance and another compound the best evidence to find a difference in the chemical properties of the reactants look for these differences.
