Question

Compounds and mixtures are both types of substances that contain different types of atoms. Alena is given a sample of material that she knows contains both Calcium and Iodine atoms. How will Alena be able to determine if this material is a compound or a mixture?
pls hurry!

Answer 1

If she can easily separate the calcium and iodine, it’s a mixture. If she can’t easily separate the two by physical means (like putting it through a filter) it’s a compound.
