Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

what method of separation is being used here?
centrifugation
In a medical lab, what method is used to separate the components of blood.
centrifugation
A bottle containing two different liquids is covered and shaken. The mixture is not homogenous and quickly separates to form two layers. What word can be used to describe the two liquids?
The two liquids are IMMISCIBLE.
In paper chromatography, the dye the move furthest up the paper is ( LEAST SOLUBLE / MOST SOLUBLE )
most soluble
Name two methods of separation that may depend on particle size.
Filtration, sieving or hand picking may be used to separate mixtures based on the sizes of component.
Name two methods of separation that depend on the density of components.
Decantation, sedimentation, centrifugation, and using the separating funnel all depending on the density of the components of the mixture.
