Fractional Distillation Quiz Questions And Answers
We welcome you to our informative Fractional Distillation Quiz Questions And Answers. Fractional distillation is a process by which elements in a chemical mixture are separated into different parts, referred to as fractions, corresponding to their boiling points. It is used to filter chemicals and separate mixtures to achieve their components. This quiz focuses on what is the first physical process in distillation & a compound containing only hydrogen and carbon called. Take this quiz and discover what you know or don't know about fractional distillation. Good Luck!
