TYPES OF CHEMICAL REACTIONS

3. Sublimation of dry ice.
4. Reaction between lead nitrate and potassium iodide present in aqueous solution.
6. You don’t start with them, but you always end with them in a chemical reaction.
8. Neither heat nor frost wakes me. Time is my weapon. Oils fall to my slow, invisible hand. What process am I?
11. A chemical duet where one dancer loses electrons while the other gains them.
12. Reaction of water with quick lime.
14. A compound falls apart when things get too heated.
16. A chemical reaction that takes place when electricity is passed through water.

1. It's a chemical dance where everything has a partner on both sides of the equation, no one gets left behind.
2. Substances that disappear as bonds break and new matter forms.
5. When bonds break and reform, giving birth to substances never seen before.
7. A reaction in which a more reactive element replaces another element in a compound.
9. A metal’s silent surrender to air and water.
10. The insoluble substance formed when two aqueous solutions mix.
13. In this class of reactions, the sum of the parts literally becomes the whole — think chemistry's way of addition.
15. A blanketing gas used to store fresh sample of oil for a long time as it prevents oil from becoming rancid.
