Mixtures can be characterized by being separable by mechanical means e.g. ), is dissolved in liquid water to form a mixture known as hydrochloric acid, HCl(aq), the hydrogen chloride is the solute, and water is the solvent. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. [8f-16] [8f-16] the boiling point is lower than pure water Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform. Hydrogen chloride (HCl), a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure. An example of this type of mixture is sugar in water. Student B – Iron sulphide dissolved inCS 2 whereas neither iron nor sulphur dissolved in the mixture. If the burning ribbon is now placed in an atmosphere of nitrogen, it continues to burn and forms a compound Y. Adequate dissolved oxygen is necessary for good water quality. The oxygen that formed combined with the iron to form iron oxide, and he collected the hydrogen gas over mercury. The lower the concentration, the greater the stress. Oxygen dissolved in water is considered as mixture … (According to mythology - … Here are some sugars: Sucrose, Lactose, Galactose, Fructose, and many more. 4. Does sand dissolve in water? Explanation: Why? In this case, lake water is not pure water, beside hydrogen and oxygen, maybe it also contain mineral and others Many common fuels, such as gasoline and kerosene, are combinations of these substances or others.
