Matter
Each pure substance has its own set of ________ or characteristics, such as colour, odour, and hardness.
physical properties,
Mixtures that look as though they have only one set of properties, such as paints, are called ________
homogeneous.
Mixtures that contain two or more materials that are still visible are called ________
heterogeneous mixtures.
Forming a solution by mixing two or more materials is called __________
dissolving.
Approximately half of your blood is made up of _____
water.
A _______ such as paint contains two or more pure substances such that each one’s properties are not lost but may be hidden.
mixture
“homogeneous” means that
every part of the mixture is the same.
A heterogeneous mixture in which the particles settle slowly after mixing is a __________
suspension.
What is the substance that dissolves in a solvent to form a solution.
The solute
When we measure how fast a solute dissolves in a solvent, we are measuring this.
the rate of dissolving
All matter can be classified into two categories. What are they?
Pure Substance and Mixture
A homogeneous mixture of substances in which no settling occurs is a _______
solution.
A heterogeneous mixture in which the particles do not settle is a _______
colloid.
What is the substance that dissolves a solute to form a solution.
The solvent
A ______ is one in which no more solute will dissolve in a specific amount of solvent at a specific temperature.
saturated solution
– contain only one type of particle
– can exist in three states of matter: solid, liquid, and gas
What am I?
Pure Substance
According to the particle model, solutions occur when
the particles of the components slip in between each other in an even distribution throughout the entire mixture.
Mixtures that are obviously heterogeneous are usually called _________
mechanical mixtures.
What does soluble mean?
Soluble means able to be dissolved in a particular solvent.
An unsaturated solution is one in which
more of the solute could dissolve in a specific amount of solvent at the same temperature.
– contain two or more pure substances
What am i?
Mixture
How can the particle model be used to illustrate a sugar and water solution
. Every sugar particle has all the properties of sugar.
Every water particle has all the properties of water. The solution blends the properties of both.
The separate parts of a mechanical mixture are called _________
phases.
Water has been called the this because it can dissolve so many materials.
“universal solvent”
A solution that contains more solute than would normally dissolve at a certain temperature is called a ________
supersaturated solution.
