Answer/s
In chemistry, a mixture is a material made up of two or more different chemical substance/substances which are not chemically combined. A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.
2. How were the different component of the moxtures separated?
Answers
Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.
3. What material did you use to separate the materials mixed? Why?
Answer/s
Solids Separation
Sieving. Just like sifting flour, we can sift Earth material. ...
Sedimentation. When small enough particles have been obtained through the crushing and sieving
process the resulting material can be mixed with water creating a slurry. ...
Flotation Tanks. ...
Magnets. ...
Filtration and Evaporation. ...
Centrifuge. ...
Distillation.
4. Which set of mixtures did you find it easy to separate? Difficult? Why?
Answer/s:
Nitrogen and Hydrogen gets react and converted into ammonia their occurs a chemical change hence separation of nitrogen and hydrogen is most difficult
5. Which set of mixtures did you find it difficult to separate? Why?
Answer/s:
salt and pepper because it's hard to separate
