Chicken Soup - 4Pure substances can be divided/sorted into two categories. What are the two types?Pure substances can be divided into two categories called,
Elements,
Compounds. - 5What is a solute?A substance that is dissolved in a solution.
- 6What is a solvent?A solvent is a substance that is able to dissolve a substance, therefore, making a solution
- 7What has the larger quantity in a solution: The solute or solvent?The Solvent has a greater quantity in a solution.
- 8What dissolves in a solvent?A solute dissolves in a solvent.
- 9What 4 things affect the solubility of a liquid?The 4 things that affect solubility are temperature, pressure, polarity, and molecular size.
- 10What is a homogeneous mixture made up of solute(s) dissolved into a solvent that has been uniformly dissolved?It is a solution.
- 11Water is the universal _________?Water is the universal solvent.
- 12The amount of solutes determines the ______________ of solutions.The amount of solutes determines the concentration of solutions.
- 13What is a saturated solution? When does it occur?A saturated solution is when a solute will no longer dissolve in a solution, they occur when you put a certain amount of solute in a solution
- 14What is an unsaturated solution?An unsaturated solution is when a solution has solute in it but if you add more solute into the solution it will dissolve, it occurs when putting a certain amount of solute into a solution
- 15What is a supersaturated solution?A supersaturated solution is when a solution has more solute than its able to dissolve
- 16does sugar dissolve faster in hot water? Why?It dissolved faster in hot water because it has faster-moving particles that are more spread apart than in cold water.
- 17What is a mechanical mixture?Mechanical mixtures are mixtures made of two or more substances that remain visible even after they are mixed.
- 18Are filtration techniques important in recycling our water? Explain why or why not?They are important because our environment needs to be healthy.
- 19Name the 6 different types of separating mixtures.Sorting, Filtration, Sifting, Distilling, Evaporation, and Magnetism.
- 20What is Sorting?Sorting is separating objects based on their appearance.
- 21What is Evaporation?Evaporation separates liquids from solids by using heat.
- 22What is Distilling?Distilling is turning a liquid into vapour and then turning it back into a liquid again.
- 23What is Sifting?Sifting is sorting solids based on their size using a mesh or screen.
- 24What is Filtration?Filtration is separating solids from liquids or gases.
- 25What is Magnetism?Magnetism is used to separate iron and steel from non-magnetic objects.
- 26What is tar sand? Is it good for the environment?Tar sand is a mixture of mostly sand, clay, water, and bitumen. and it is bad for the environment.
