mixture is 混和物
A mixture is formed when mixing different materials which may be all sorts of things
Milk, Salt Water, oil, and soup are all mixture. When we talk about mixture, we think of it as something contrast to pure substance.
A compound is 化合物, according to Merriam Webster's on-line dictionary,
It is: something formed by a union of elements or parts; especially : a distinct substance formed by chemical union of two or more ingredients in definite proportion by weight
A compound is usually formed by the force of chemmical bonds between different chemical elements..
CO2(Carbon and Oxygen), NaCl(Sodium and Chlorin), NaHCO3....are all compounds, not mixture. Conmparing to mixtures, they're pure substances.
混合物是相較純物質說的,只要是任何東西混合在一起就可以組成
牛奶.鹽水.都是
化合物是相較單一元素組成的物質說的,透過化學鍵結組合把不同元素組合在一起.單一元素組成的物質例如鐵(Fe).銅.(Cu)
化合物例如精鹽(NaCL鈉和氯).碳酸鈣(CaCO3)
化合物本身是純物質.
