Question | Answer |
matter | •Has mass (g, kg). •Takes up space or volume (mL,L or cm3, m3). •EVERYTHING AROUND US. |
mixture | •Made up of 2 or more substances. •Can be made up in different ways (ie. different concentrations, or combinations), therefore, a mixture does not have fixed chemical composition, or a chemical formula. •Properties of a mixture are the blended . . |
Heterogeneous | Heterogeneous is an adjective that describes substances or materials. •means not the same throughout. •Usually more than 1 visible phase is obvious with the naked eye |
Solutions | Homogeneous mixtures. •Made up of a solute and solvent. •Solute dissolves into the solvent. •One visible phase. •Solutions can be made up of solids, liquids and gases. meateals as well |
Homogeneous | Homogeneous is an adjective that describes substances or materials. •means the same throughout – same composition and concentration – uniform appearance. •One visible phase is seen with the naked eye (without a magnifier). No visible “bits” or layers. |
Pure Substances | Are compounds or elements. •Are truly homogenous - with the same composition and concentration throughout. •Have one visible phase. •Can be described with a chemical formula and has a fixed ratio of elements. Made up of all the same particles |
Compounds | 2 or more elements bonded together to make molecule. •Compounds of the same substance have the same chemical formula the same chemical composition.water is H2O – 2 hydrogen atoms bonded to 1 oxygen atom. •Ex: salt – , water – H2O, carbon dioxide – CO2. |
Elements | Made up of atoms. •One visible phase – the same composition and concentration throughout. •Elements can be found on the periodic table. •Atoms are the building blocks of matter. •Examples: iodine crystal – I, iron – Fe, H – hydrogen, C – carbon. |
Solid | A state of matter • Definite shape •Definite volume •Particles are very close together •Particles stay in the same position but rotate a little |
Liquid | difinent volume. changing shape, medeaim space bettweenparticals, medeam attraction of paricals. |
gas | in defentent volume and shape, large shpace bettween particals, but movment bettween particals is very fast. |
plasma, | the forth state -o-f matter a has that is alectrisity charged, mainly stars and nuculas in outer space. |
partical theroy | all matter is made up of tiny particals, that have spaces bettween them, allwaysmoveing. when heated particels move faster and pread apart. |
Mechanical Mixture | diffrent parts that you can see mixted together, also known as a homogeneois mixter |
Change of State | when a substance changes its state of matter. |
Solute | the smaller part that is being disolved. |
solvent | the larger part that is dissolveing the solute |
Types of Solutions | when i solute and a solvent is mixed. |
Solubility | how well something idsolves |
Factors that Affect Solubility | factors are: temperature, crushong the solute, and stiring the solution. |
