halite
Calcite
Reagent: Add dilute Hydrochloric acid [HCl] Inference: Effervescence and a gas which turns limewater milky [CO2 ] Equation: CO32- +2H+ -> H2O + CO2
Talc is insoluble in water and only slightly soluble in dilute mineral acids.
When zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2.

It is most likely to contain the mineral calcite.

To dilute mineral oil, you can mix it with a carrier oil such as olive oil or coconut oil. Start by adding a small amount of carrier oil to the mineral oil and mix well. Gradually increase the amount of carrier oil until you reach your desired dilution ratio. Be sure to stir or shake the mixture thoroughly to ensure even distribution.
Quartz
For simple identification purposes you should ask: what is the hardness of the mineral compared to other minerals; what is the color (streak) of the mineral when scratched on an unglazed porcelain ceramic surface; and does the mineral react with dilute hydrochloric acid or vinegar, indicating whether or not it's a carbonate mineral. Other identifiers would be the mineral's specific gravity, lustre, and crystal classification.
Put a few drops of dilute hydrochloric acid on both samples. Both will fizz indicating the presence of calcite.
You would see bubbles (effervescence) of Hydrogen gas being given off as the reaction happens.Magnesium + Hydrochloric acid ------> Magnesium Chloride + HydrogenMetal + acid ------> Metal Salt + Hydrogen
Some minerals give off carbon dioxide bubble when acid is dropped on them. Geologists have termed this as the "acid test".
