Fill the blank ____ is anything that has volume and mass
Matter
What is the term for this concept? Name given to the model representing the organization and behaviour of matter. According to this model: * Matter is made up of particles * All particles are in constant motion
PARTICLE MODEL
Name the phase • Definite shape • Definite volume • Particles vibrate • Particles tight together.
Solid Phase
Name the phase • Takes shape of container • Definite volume • Particles slide over each other • Particles a little further apart than solid
Liquid Phase
Name the phase • No definite shape • Particles move freely • Particles are far apart
Gaseous Phase
Which term refers to this definition? Smallest, indivisi- ble unit of matter that exists.
Atom
Which term refers to this definition? Groups of 2 or more atoms held together by chemical bonds.
Molecules
Which term refers to this definition? Substance made of at least two different types of particles.
MIXTURE
Which term refers to this definition? Substance made up of a single type of atom or molecule.
PURE SUBSTANCE ex: H2, Cu, H2O, CO2 are all exemple of pure substance.
Fill the blanks Mixtures fall into two categories: ____ mixture and ____ mixture.
heterogeneous mixture and homogeneous mixture.
Which term refers to this definition? A mixture containing at least two substances that are visibly distinct
HETEROGENEOUS MIXTURE ex: orange juice with pulp
Which term refers to this definition? Mixture made up of at least two sub- stances that cannot be distinguished with the naked eye.
HOMOGENEOUS MIXTURE ex: apple juice, blood, urine
Which term refers to this definition? Homogeneous mixture in which a solute is dissolved in a solvent.
SOLUTION
Exemple of problem related to solution Sport drinks are considered aqueous solutions. Below is the ingredient list for one of these drinks. Ingredients: Water, sucrose syrup, glucose-fructose syrup, citric acid, natural grape flavour with other natural flavours, salt, sodium citrate, red41, blue 1. Identify 3 solutes found in this sports drink.
Any 3 or the following: * sucrose syrup, * glucose-fructose syrup, * citric acid, * natural grape flavour with other natural flavours, * salt, * sodium citrate, * red41, * blue 1.
