What is matter
Anything that has mass and takes up space
100
What is chemical reaction
Another name for chemical change, a process that involves one or more substances changing into a new substance
100
What is the law of conservation of mass
Mass is neither created or destroyed during a chemical reaction, it is conserved
100
What is mixture
The number of these possible to create are infinite
100
What is an element
Pure substance that cannot be separated into simpler substances by physical or chemical means
200
What is a pure substance
Table salt is an example of this
200
What is phase change
Transition of matter from one state to another
200
What is the law of definite proportions
A compound is always composed of the same elements in the same proportion by mass, regardless of the sample size
200
What is heterogeneous
Salad dressing is an example of this mixture, whose composition is not uniform and substances do not blend smoothly
200
What are groups/families
Elements that have similar chemical and physical properties are classified as this
300
What is a solid
Concrete and Wax
300
What is physical change
Condensation, solidification and boil are all key words for this process
300
What is Mass of Element divided by Mass of Compound multiplied by 100
This formula tells us the ratio of the mass of each element to the total mass of the compound expressed as a percentage
300
What is gas-liquid
When oxygen and carbon dioxide are dissolved in seawater this type of system is in play
300
What are compounds
Using heat or electricity, one can separate these into simpler substances
400
What is a vapor
Gasesous state of substance that is a solid or liquid at room temperature
400
What is chemical change
Aluminum combing with oxygen to form aluminum oxide is an example of this
400
What is the product
A student carefully placed 15.6g of sodium in a reactor supplied with an excess quantity of chlorine gas. When the reaction was complete, the student obtained 39.7g of sodium chloride. Sodium chloride is this part of the equation
400
What is crystallization
Separation technique that results in the formation of pure solid particles of a substance from a solution containing dissolved substances
400
What is water
At room temperature, this is a stable compound that when broken down becomes highly reactive with many elements
500
What is extensive
Mass, length, and volume are dependent on the amount of substance present, which makes them this type of properties
500
What is a physical change
The process when at atmospheric pressure and 0 degrees Celsius, water is ice. As heat is added to the ice, it melts and becomes liquid water. When the temperature increases up to 100 degrees Celsius, water boils and becomes steam
500
What is 8.4g Carbon / 20.0g Sucrose x 100
A 20.0g sample of sucrose contains 8.4g carbon. This is the setup to determine mass percentage of sucrose
500
What is sublimation
Process during which a solid changes to vapor without melting
500
