Matter
Name one thing that is made of matter
Books, cats, snow, air
Which state of matter is made of large clusters of particles?
Solid
What type of property is flammability?
Chemical property (has to change to a different substance to observe it)
Which of the following is a compound: Sucrose, steel, beef stew, soil?
Sucrose
Which can be separated by physical means:
Pure matter
or
Mixtures
Mixtures
Which varies with location: mass or weight?
Weight
Which state of matter has an indefinite volume and an indefinite shape?
Gas
What type of property is length?
Physical property that does change with amount (extrinsic)
What is one difference between homogeneous and heterogeneous mixtures?
Homogeneous are thoroughly mixed, heterogeneous you can see differences. Heterogeneous may separate on their own. Homogeneous must all be the same state of matter.
Which of the following is true about compounds:
They have properties different from those of their component elements
Define matter
Anything that has mass and takes up space
Why do liquids have a definite volume but no definite shape?
Their particles are loosely bound but can slide past each other.
What must happen for a change to be a chemical reaction?
There must be a change in chemical properties
Which one is a difference between a mixture and a compound?
A mixture can be separated by physical means
Why is N2 not a compound?
Because it does not have more than one element
Name one thing NOT made of matter
Light, electricity, thoughts
Define vapor
A gas that exists below its boiling point
What type of property is tendency to rust?
Chemical property
Name a homogeneous mixture
Sugar water, air, metal alloys, salt water, vinegar
Why is salt not an element?
Because salt is made of sodium and chloride, making it a compound
How do you measure mass?
With a balance
Give an example of a vapor
Humidity, fumes from gasoline or nail polish remover
What type of property is density?
Physical property that doesn't change with amount (intrinsic)
Why are the following not heterogeneous mixtures: salt, baking soda, air?
Salt and baking soda are compounds, air is a homogeneous mixture
Which of the following is not a physical property of water:
Freezing point of 0 Celsius
