200
You are examining an object that is solid, does not conduct electricity/heat, is malleable, and a shiny silver color. Is it a metal, nonmetal, or metalloid?
metalloid.
200
A mineral sample you found can scratch glass (on the Moh's Scale this falls BETWEEN Apatite and Feldspar), but will NOT scratch Quartz. This means that it is _______ (harder/softer) than ____________, but (harder/softer) than Quartz.
Harder, Fluorite, Softer.
200
Calculate the mass of an object that has a volume of 6 cm and a density of 13 g/cm.
Step 1: The formula for finding Mass = DxV Step 2: DxV (13g/cm x 6 g) Final Answer: 78 g/cm
300
Na is the symbol for _________.
Sodium.
300
What three elements comprise (make up) the Atmosphere?
Nitrogen, Oxygen, and Others.
300
You are examining an object in science class that is pale yellow, brittle, solid, and is not shiny (luster). Is it a metal, nonmetal, or metalloid?
Nonmetal.
300
Malleability, Luster, Ductility, Conductivity, and Oxidation are ALL examples of ___________ properties.
Physical
300
Calculate the volume of an object that has a mass of 45 g and a density of 9 g.
Step 1: Volume = M/D Step 2: Volume = 45g/9g Final Answer: Volume = 5g
400
An element is a pure____________.
substance.
400
What element makes up the majority (biggest part) of the Earth's crust?
Oxygen (47%)
400
If you wanted to find a solid material that conducts heat/electricity, is solid, and is ductile (can be stretched into a thin wire), you would need a ___________. Choose: metal, nonmetal, metalloid
Metal.
400
You and a partner are conducting two DIFFERENT types of experiments. What are you BOTH doing during those experiments?
Making observations.
400
Calculate the density of a cube that measures 5 cm on one side, and has a mass of 10 g.
Step 1: Volume = LxWxH (5x5x5) = 125 cm3 Step 2: Density = M/V (10g/125cm3) = 0.08 g/cm3 Final Answer: Density = 0.08 g/cm3
500
Short Answer: Even though the Earth's crust is mostly made up of Oxygen (47%), why can't you breathe it?
The oxygen is combined with other elements to make things, such as Quartz.
500
What is the chemical symbol for Iron?
Fe
500
Two samples of mineral have the same mass. This does not mean that they necessarily have the same ___________.
Density.
500
You and your group are conducting a lab investigation. What procedure should you do to ensure that all the data you collected is reliable?
Record all data as soon as it is collected.
500
Calculate the density of a cube that measures 7 cm on one side, and and has a mass of 5 g.
Step 1: Volume = LxWxH (7x7x7) = 343 cm3 Step 2: Density = M/V (5g/343cm3) = 0.014g/cm3 Final answer: The density of the cube is 0.014 g/cm3 or 0.015g/cm3 if you rounded up.
