Baking soda & vinegar can be used to model a volcanic eruption in a science demonstration because they bubble violently when mixed. What conclusion can be drawn about mixing vinegar & baking soda?
vinegar & baking soda react to form a new gaseous substance
baking soda & vinegar make a uniform mixture
vinegar boils when it comes in contact with baking soda
baking soda has a lower density than vinegar
Homemade ice cream can be made by adding milk, sugar and vanilla together and bringing the mixture to a temperature below freezing and the mixture freezes. When this is done in the classroom what kind of change is happening?
chemical change
physical change
transitional change
A teacher gives her students a small aluminum cube along with a list of properties. The students are then asked to see if a different metal cube is made of aluminum. Infer the single property listed on the table which would best help the students determine that the cube is aluminum.
length of each side
volume
melting point
mass
A cup of gold colored metal beads was measured to have a mass 425 grams. By water displacement, the volume of the beads was calculated to be 48.0 cm3. Given the following densities, identify the metal.
Gold: 19.3 g/mL
Copper: 8.85 g/mL
Bronze: 9.87 g/mL
gold
copper
bronze
none of these
Which of the models represents a compound?
Which of these models represents an mixture?
Abner is researching the physical properties of pure copper. He makes the table given. Draw a conclusion about the copper sample using evidence from Abner's table.
Increasing the mass of copper does not change the physical properties of copper.
Decreasing the mass of copper decreases the melting point of copper.
Increasing the mass of copper always changes the color of copper.
Decreasing the mass of copper increases the density of copper.
The shapes are floating in water. Which shape is the most dense? Least dense?
Most = B Least = F
Most = C Least = B
Most = B Least = C
Most = A Least = C
A piece of wood that measures 3.0 cm by 6.0 cm by 3.0 cm has a mass of 27.0 g and a volume of 54 cm3. What is the density of the wood? Don't forget proper units.
Will the piece of wood float or sink in water?
0.5 g/cm3 - float
0.5 g/cm3 - sink
2 - sink
2 g/cm3 - float
Which is NOT a clue that could indicate a chemical change has occurred?
Color change
Odor change
Energy change (given off or gained)
Shape change
