  • What is the difference between a heterogeneous mixture and a homogeneous mixture?
    het. unevenly distr. hom. evenly distributed
  • True or False? A solution is a type of mixture.
    true
  • What do you call a mixture of two or more metals?
    an alloy
  • True or False? In many mixtures, the different materials are uniformly distributed.
    false
  • If you were to magnify a section of a solution and you took two separate samples of the same solution, what would you see?
    They would be the same.
  • True or False? Alloys are not considered solutions because they are made of two or more metals.
    false
  • Give an example of a homogeneous mixture.
    various answers
  • Identify THREE ways you could separate a solution.
    Melt it. Boil it. Allow it to evaporate.
  • Give an example of a heterogeneous mixture.
    various answers
  • Which ONE is not true for a solution? (heterogeneous - homogeneous - mixed at atomic level)
    heterogeneous
  • True or False? A mixture is a physical combination of two or more elements.
    false
  • Why CAN you represent a compound with a chemical formula?
    It has a definite composition.
  • Why is it relatively easy to separate a mixture (consider ALL mixtures)?
    Each substance keeps its properties - not chemically combined.
  • Why would I manipulate the amount of carbon in my steel?
    to affect the hardness
  • How many substances make up a mixture?
    two or more
  • Why CAN’T you represent a mixture with a chemical formula?
    It does not have a definite composition.
  • True or False? Bronze is an alloy made of copper and tin.
    true
  • What is the solvent in seawater?
    water
  • What is a difference between a mixture and a compound?
    mixture - physica/different composition l compound - chemical/same composition
  • Why would anyone in their right mind want to mix two metals together?
    To make bronze/steel - tools, weapons, sculptures, etc.
  • Other than a solid dissolving into a liquid, give TWO other examples of solutions.
    gas and liquid - metal and metal
  • Why would a filter NOT be the best way to separate a solution?
    The particles/molecules are too small to be trapped in most filters.
  • True or False? A salad is a solution.
    false
  • True or False? Solutions always involve a solid dissolving into a liquid.
    false
  • What is the solute in seawater?
    salt
