What Students can use to distinguish pure substances?
Students can distinguish pure substances from mixtures by observing their physical properties, such as melting points, boiling points, and solubility. Pure substances have specific and consistent properties, while mixtures may exhibit a range of properties. Additionally, techniques like chromatography or filtration can be used to separate components in a mixture, confirming the purity of a substance. Conducting tests for chemical reactivity can also help identify pure substances versus mixtures.
Who would use chromatography?

You can use your senses to observe of a substance?
Yes, you can use your senses to observe properties of a substance. For example, you can use sight to observe its color and texture, smell to detect any odors, touch to feel its texture and temperature, and taste to determine its flavor.
Are a substance and a pure substance the same thing?
Technically, a non-pure substance is called a compound, so substance should not be used as an official scientific term. If you do come across the term 'substance', use context to decide. e.g. "Scientists isolated the substance boron." would be a pure substance, as boron is a single element.
What term would you use to classify the two substances of how their atomic mass and atomic number?
They are isotopes.
What are the pure substance which you use in day to day life?
