7. Classify as an element, compound, or mixture
An unknown, clear liquid is given to you in a beaker. You transfer the liquid from the beaker to a clean, empty test-tube, and begin to heat it. After a while, you see vapors (which on further analysis you discover are vapors of water) rising from the test-tube, and pretty soon, all that's left are a few crystals of salt stuck to the edges! How would you classify the unknown liquid?
MIXTURE

8. Classify as an element, compound, or mixture
You have won the world's biggest lottery, for which you are given a huge block of pure, metallic gold. How would you classify this substance?
ELEMENT

9. Classify as an element, compound, or mixture
A dish is given to you, which contains a blackish-yellow powder. When you move a magnet over it, you are amazed to see black particles, (which you find out are iron) fly upwards and get stuck to the magnet, and all that's left in the dish is a yellow powder, which you discover to be sulfur. How would you classify the original powder?
MIXTURE

10. Classify as an element, compound, or mixture
A substance is analyzed in a laboratory, and when viewed under an electron microscope, it is revealed that it contains only one kind of atom. How would you classify the substance?
ELEMENT

11. Classify as an element, compound, or mixture
This gas is essential for us, and all other aerobic organisms, to survive. We inhale it along with the air we breathe (of which it forms approximately 21%) and it then helps in the oxidation of glucose in our bodies.
When not in its molecular form, how would you classify the substance?
ELEMENT

12. Classify as an element, compound, or mixture
Water is what all life in the world depends on.
How would you classify water?
COMPOUND

13. Classify as an element, compound, or mixture
A magnesium ribbon is burnt in the air, to form the grayish oxide of magnesium - magnesium oxide (MgO). How would you classify this oxide?
COMPOUND

14. Classify as an element, compound, or mixture
How would you classify the air we breathe?
ELEMENT

15. Classify as an element, compound, or mixture
These are given 'symbols' like 'Ar', 'Zn', 'W' and 'Xe', and are arranged in a table called the Periodic Table. How would you classify these substances?
ELEMENTS

16. Classify as an element, compound, or mixture
An unknown silvery powder has a constant melting point and does not chemically or physically separate into other substances. How would you classify the unknown substance?
