Solutions
What are solutions?
Solutions are two or more substances that cannot be separated.
What are mixtures?
Mixtures are two or more substances that can be separated.
Mixtures and Solutions are the same.
False they are not the same.
What is called if a solution or mixture have a uniformed composition?
They are called homogenous.
When particles get hot what do they do?
They move faster.
When looking at a particle model, which state of matter has all particles neatly arranged and tightly packed?
Solid
What are the two things that create a solution?
They are solutes and solvents.
Why can mixtures be separated?
They can be separated by the differences in their physical properties.
Solutions do not need a solvent.
False
Something that dissolves into a liquid to create a solution.
It is a solute.
What is a particle theory?
Particle theory is all matter that are made up of tiny particles like atoms or molecules and are always moving.
When looking at a particle model, which state of matter has all particles spread far apart with no fixed shape?
Gas.
Define a solvent.
A solvent is what a solute needs to dissolve into.
What are homogenous mixtures?
Combination of two or more substances that has a uniform composition and appearance throughout. No matter where you take a sample of the mixture, it will contain the same proportion of its components. You cannot visually distinguish the individual parts.
Mixtures need pure substances.
True
Two things that mixed that can be separated
Its a mixture
True or False particles are far apart from each other.
False.
What happens if we apply heat (energy) to a liquid?
It will eventually turn into a gas
Define a solute.
A solute needs to dissolve into a solvent.
What are heterogenous mixtures?
Combinations of two or more substances where the components are not uniformly distributed. The different parts are usually visible to the naked eye, maintain their individual properties, and can be separated easily through physical means (like filtering or straining).
Solvents are dissolved into the solute.
False
Two things that mixed that cannot be separated
It is a solution
What has a fixed volume but not a fixed shape.
Liquid.
What are the main states of matter?
Solid liquid and gas.
Summarize what a solution is.
Solutions cannot be separated and can contain anything that is a solute and solvent.
Summarize mixtures?
Mixtures can be separated and are created by pure substances.
Mr Mitchell is the best teacher.
True
What is the universal solvent?
H2O - Water.
What has no fixed volume and no fixed shape?
Gas.
What is meant by the term dissolve?
to mix a solid into a liquid, creating a uniform solution.
