Three Things We Used In our Daily Life
The detergent is used to clean the dishes and bowls, if you use it, the dishes and bowls you washed will be cleaner.
The firework is used in the celebration because of the Chinese tradition.
The lighter is the thing we use to light something when we need to get fire easily.
Washing the dishes or bowls
Using for celebration
Making something burning
Corrosion remover, NaCl , H2O
C, Sulphur, Al, CaO
For the substances we are familiar:
H2O, NaCl and C. We almost use them everyday to keep our lives.
For the substances we are unfamiliar:
CaO, Al and C4H10. CaO maybe we can see it in our daily lives because it is one of the main materials of the antiseptic. However, about other substances, they are not used often in our daily lives like Al and C4H10, it’s dangerous because it is easy to explode.
The similarities and differences
The similarities: From the names of the substances, they can also give us some information. Like C and C4H10, these substances can be burned.
The differences: From the names of the substances, such as H2O and Al, one is the thing that can’t be burned, and the other is really easy to burn or explode.
Green label is marked by government departments and public or private organizations in accordance with certain environmental standards. If the products have the green label, then it means that this kind of product wouldn’t be harmful to the environment, humans, animals, plants or other lives.

The things happened to substances
Detergent made the dirt of the bowls (heterogeneous)on the bowl turn into homogeneous.
When we were young, we played with fireworks, it became another kinds of heterogeneous.
The gasoline in the lighter became homogeneous after burning.
We think that we should keep using these things. We’ve already gotten used to a saying ”Each coin has two sides.”In the one hand, it can be dangerous; but in the other hand, we can improve them as we are using them. Because we believe that no problems no progress.
About this question, we choose one of the most normal and important compound in our daily—NaCl in the detergent. About the issues of it, some people say that we are not supposed to use it because some kinds of detergent can pullute our water and environment. Its properties are that it has water-solubility because it can be dissolved in the water, it is white solid, and it has stability although it is not very good. We can use as salt, for it is the main part of the salt. We can evaporate the seawater to get it. This is the most common way. For disposal, since it is not dangerous, so when it gets outside, we just need to clean it up.
