Chemistry Retake Unit Test Review

If you were finding the amount of particles in a wooden block, you'd be finding the block's:

• mass

• weight

• volume

• density

Which of the following statements show how mass and volume are similar?

• mass and volume are both size independent

• mass and volume are determined by gravitational force

• mass and volume are both size dependent

• mass and volume are found using beakers or flasks

Which of the following units are used to measure volume?

• cubic centimeters

• liters

• both of these

• neither of these

If you placed a copper block in a graduated cylinder filled with 45 mL of water, and the water rose to 70 mL, what would be the volume of the copper block?

• 25 mL

• 2.5 mL

• 70 mL

• 105 mL

If you had a rectangular prism with a length of 5 cm, a width of 5 cm, and a height of 10 cm, what is the volume of the prism?

• 250 cm3

• 25 cm3

• 20 cm3

• 2,500 cm3

Why is density best used to identify an unknown substance?

• each element on the Periodic table has its own unique density

• density will not change with gravitational force

• density is the only physical property that is size dependent

• density can easily be found by placing an object in water

If a brick had the mass of 2,556 grams and a volume of 3,997 mL, what would its density be?

• .63g/cm3

• 630 g/cm3

• 1,441 g/cm3

• 6,533 g/cm3

If you chopped a large piece of wood into several smaller logs, this would be an example of:

• a physical change

• a chemical change

• a reactive change

• an oxidative change

Why would your weight be different on the moon, but not your mass?

• weight is determined by the force of gravity

• weight is determined by the gases in the atmosphere

• weight is determined by the average temperature of the atmosphere

• weight is determined by how quickly a planet or moon is rotating

If you were needing to find the density of a very hard, shiny, yellow colored bar to see if it was gold, which two instruments would you use?

• digital scale and beaker

• composition notebook and magnifying glass

• computer and a microscope

• flask and a pipette
