Sample Question

When we cook a viand for dinner, we mix different ingredients. In scientific and chemical definition, the “mixture of ingredients” is technically not a mixture. Why is this?

  • It is not a mixture because it can still be separated.
  • It is not a mixture because it is homogenously mixed.
  • It is not a mixture because there is a chemical reaction.
  • It is not a mixture because there is no chemical reaction.

This is just one of our 120,510 study questions in Quipper School.
