What are pure substances solutions homogeneous mixtures colloids or compounds?
Compounds and solutions are pure substances
Why are solutions mistaken for a pure substances?
Solutions are mistaken for pure substances because they often appear uniform and have consistent properties throughout the mixture. However, solutions are actually a homogeneous mixture of two or more substances, where one substance (solute) is dissolved in another (solvent). This is different from a pure substance, which consists of only one type of particle.
What evaporates pure substance or solutions?
Both pure substances and solutions can evaporate, but they do so at different rates and under different conditions. Pure substances, such as water, will evaporate at a specific temperature and pressure, while solutions may evaporate more slowly due to the presence of solutes, which can lower the vapor pressure. The rate of evaporation depends on factors like temperature, surface area, and air movement, regardless of whether the material is a pure substance or a solution.
Are HCl aq NaCl aq HCl g and NaCl s substances?
If you mean pure substances then:HCl(aq) and NaCl(aq) are not pure substances but solutions. The (aq) means the substance is dissolved in water.HCl(g) and NaCl(s) is are pure substances
What are pure substances A solutions Bcompounds C homogeneous mixtures D colloids?
compounds
Into what two broad classes can all matter be divided?
Pure substances (elements and compunds) and mixed substances (mixtures, solutions, alloys).
How do you distinguished between mixtures and pure substances?
A pure substance has only one of atom or molecule. A mixture has a number of different pure substances mixted toghter.
How are pure substances and solutions alike?
no, solutions are not pure substances because all though they may look that way to the naked eye, the definition of a solution is a mixture where one substance has completely dissolved into the other. such as salt water. you can see only the water but you know the salt is there because when it dries out, the salt is left over.
Is silver a mixture?
No, silver is a pure element because it is made up of only one type of atom (Ag). It is not composed of different substances mixed together.
Does a pure substance describes elements and compounds but not mixtures or solutions?
"Pure" generally implies that the object has no unwanted material. It can include mixtures and solutions. For example, Ivory soap is advertised as being 99.9% pure meaning it has nothing in it that they didn't intend to put in the soap.
What property of pure substance is similar to solution?
Both pure substances and solutions have specific physical and chemical properties that are unique to their composition. Both can exist in different phases (solid, liquid, gas) and exhibit properties such as boiling point, freezing point, density, and solubility that are characteristic of their chemical makeup. Additionally, both pure substances and solutions can undergo physical changes such as melting, boiling, and dissolving without changing their chemical composition.
Substances are divided into two classes?
Some people divide matter into pure substances and mixtures. Pure substances are elements and compounds. Mixtures include homogeneous and heterogeneous mixtures. Some people divide matter into homogeneous matter and heterogeneous matter. Homogeneous matter includes pure substances and homogeneous mixtures (solutions). Heterogeneous matter is heterogeneous mixtures.
