  • what are the two classification of mixtures?
    HOMOGENEOUS & HETEROGENEOUS
  • Solution and Suspension can scatter a light. Is it TRUE or FALSE?
    FALSE
  • What do we call the material which traps the dispersed material?
    DISPERSED MEDIUM
  • Give a clear sign that a mixture is a SUSPENSION.
    Particles settle down below or above the mixtures. Large particles can still be seen by naked eye.
  • What type of solution is carbon dioxide?
    GAS IN GAS
  • It refers to the smaller amount that is broken down in a solution.
    SOLUTE
  • What type of solution is alcohol and water?
    LIQUID IN LIQUID
  • What is the common solvent?
    WATER
  • It is a mixture where the particles do not completely dissolve and settle down at the bottom or above.
    SUSPENSION
  • Give a clear sign that a mixture is a Colloid.
    has a cloudy / foggy appearance. Some small particles can still be seen.
  • what type of colloid mayonnaise is?
    EMULSION
  • It refers to substances that are physically combined, mixed, or put together. It can be easily separated.

  • Homogeneous mixtures are combined in such a way that they have different uniform phase all throughout. TRUE or FALSE?
    FALSE
  • It refers to the trapped material in a colloid mixture.
    DISPERSED MATERIAL
  • What is the Greek word for homogeneous? And its meaning.
    "homos" which means same and "genes" which mean kind
  • It is a homogeneous mixture, it refers to a mixtures where the particles mixed or dissolved in it cannot be distinguished by naked eye.
