This Canadian landform feature reached it's peak during the Precambrian Era.
What is the Canadian Shield
100
A characteristic of a substance that you can observe and measure without changing the identity of the substance
What is a physical property
100
Mendeleev found this pattern in elements and used it to organize them into a table.
What is increasing atomic mass
100
This is the type of bond that forms when atoms form a molecular compound achieving full outer energy levels and therefore more stability by sharing their valence electrons.
What is a covalent bond
200
This acronym is used for the organization that provides safety information and instruction in lab settings
What is WHMIS- Workplace Hazardous Materials Information System
200
This if formed through the process of lithification and compaction.
What is sedimentary rock
200
This property can be observed and described without detailed measurement
What is a qualitative physical property
200
Elements are classified into these three categories on the periodic table
What is metal, non metal and metalloid
200
These are the steps that occur in the process of eutrification
What is
- farm run off adds nutrients from fertilizers to water systems
-algae bloom forms due to excessive nutrients
-oxygen in water is used up when algae decomposes
-fish die from lack of oxygen
300
This process can be used to separate liquids in a mixture based on boiling point
What is distillation (a liquid with a lower boiling point that other components in a mixture, is vapourized, condensed, and collected in a beaker)
300
A mineral that releases energy when burned.
What are fossil fuels
300
These are five examples of QUANTITATIVE physical properties
What is (select from the list)
-viscosity, melting point, boiling point, solubility, hardness, conductivity, density
300
The term given to describe a vertical column of elements in the periodic table
What is group
300
This element while useful in measuring the temperature is also found in fish with toxic consequences for some cultures
What is mercury
400
This substance can only be broken down by chemical methods
What is a compound (elements in a compound are chemically combined- thus can only be broken down by chemical methods eg. to break down water into hydrogen and oxygen, use a chemical process called electrolysis)
400
Milling, smelting, tailings and slag
What are steps in the processing of metallic minerals
400
A measure of the ability of a substance to dissolve in another substance
What is solubility
400
This is the name and group of elements that are non-metals and are all odourless, colourless gases at room temperature
What is Noble Gases, Group 18
400
These represent two of the steps in the development of Dalton's Model of the Atom
What is
-all matter is made up of small particles called atoms
-Atoms cannot be created, destroyed, or divided into smaller particles
-All atoms of the same element are identical in mass and size. The atoms of one element are different in mass and size from the atoms of other elements.
-Compounds are created when atoms of different elements link together in definite proportions
500
These are three points that make up the ideas that support the "Particle Theory of Matter"
What is
- all matter made up of tiny particles
-each pure substance has it's own kind of particle, different from the particles of other pure substances
-particles attract each other
-particles are always moving
-particles at a higher temperature move faster, on average, than particles at a lower temperature
500
These were the theories proposed by Wegener to explain contintental drift
What is jigsaw shape, fossils of plants and animals, geological structure (mountains), ancient ice sheets.
500
Is the formula used to calculate this quantitative property that is ultimately expressed in g/cm3.
What is density = mass/volume
500
This happens when ionic compound forms
What is one or more electrons from one atom are transferred to another atom, producing oppositely charged ions that are attracted to each other.
In the formation of ionic compounds, the loss and gain of valence electrons between the reacting elements allows each ioin to have a full outer energy level of electrons.
500
These are the formulas used to calculate the mass number and the number of electrons
What is
mass number = number of protons + number of neutrons
number of electrons = number of protons (neutral atom)
(atomic number= number of protons
number of neutrons = mass number - atomic number)
