Properties and Changes

2. Demo’s Copper II Chloride (Copper Chloride) and Aluminum demo
6Al(s)  +  6CuCl2(s)  +  6H2O(l)  -->  2Al(OH)3(aq) + 4AlCl3(aq) + 6Cu(s) + 3H2(g)
Basically I made Hydrogen Gas and turned some of the Aluminum (foil) into Copper.
The blue flame that you see indicates that Hydrogen Gas is burning.

3. Demo’s Zinc and Hydrochloric Acid
Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
What I did with this reaction is turn Zinc into an aqueous solution of Zinc Chloride and released Hydrogen Gas in the process.
The blue flame that you see indicates that Hydrogen Gas is burning.

4. Demo’s Barium Hydroxide and Ammonium Nitrate
Ba(OH)2.8H2O(s) + 2NH4NO3(s) + D —> Ba(NO3)2(aq) + 2NH3(aq) + 10H2O(l)
This reaction is quite a bit more complicated. But to put it into simple terms, I took two solids – Barium Hydroxide and Ammonium Nitrate – and mixed them together. They absorbed the heat (and moisture) in the air to mix together. When it did this, it turns into an aqueous solution with some water and the temperature drops radically.

5. Demo’s Lighting a Candle Is a combustion reaction
Hydrocarbon+ O2(g) ---CO2 + H2O

6. What in the world isn’t Chemistry
Think about it for a minute, and I challenge you to think about one thing that is not some sort of chemical reaction, or some sort of chemistry in this world.

7. What is Chemistry? From the smallest (atoms) to the largest materials
Take our Copper Chloride experiment. I literally took a solid material (Copper Chloride), ripped it apart with water into two groups of ions – Copper and Chloride – and then I took the atoms of Aluminum and swapped it with Copper to make a brand new product – Aluminum Chloride and a solid atom of Copper particles. AMAZING !!!!!

8. What is Chemistry Study of the structure of matter
Atomic or molecular properties and how it affects material properties
Study of the changes that matter undergoes (reactions)

9. Why Study Chemistry? ACTIVITY CHEMISTRY Had a shower Surface
Put on Deodorant Biochemistry
Put on Makeup Colors
Put on Aftershave Fragrances
Put on Clothes Polymers
Sitting in your chair Polymers that will not break

10. Doing Chemistry Everyday
ACTIVITY CHEMISTRY
Made Breakfast Food
Ate Breakfast Metabolic
Had a Cigarette Drug
Travelled on the Bus Combustion Pollution
Wrote Notes Surface

11. Doing Chemistry Everyday
ACTIVITY CHEMISTRY
Breathing, Biochemistry
Thinking Biochemistry
Electrochemistry
Being Organic Chemistry

12. Types of Chemistry Organic – Carbon containing molecules
Inorganic – Often metals and non-carbon atoms and molecules
Physical (Physics) – Mechanisms, energy flow, heat, light, power
Analytical – Identification and measurement (my favourite). Lots of math and theory
Bio – Chemistry of Life

13. Better Life Through Chemistry
Disinfection of drinking water by chlorine
Chemical fertilizers and pesticides
Synthetic polymers
Fewer cavities (fluoridation of water)
Junk food

14. Better Life Through Chemistry
Drugs – Medication
Acetaminophen and Ibuprofen

15. e.g. making water 2 H2(g) + O2(g)  2H2O(g)
What are the reaction steps?
Is heat released?
How fast is this reaction?
When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy (heat) is released and the molecules of hydrogen and oxygen can combine to form water.

16. But...
Combining the exact same atoms, but with a different ratio we get Hydrogen Peroxide (a weak acid)
2 H2(g) + 2O2(g)  2H2O2(g)

17. Or even more interesting
Chlorine gas – Cl2 is a green and very poisonous gas. It was used in WWI by the Germans against the British army.

18. But if you mix Chlorine with Urine (the salts in the Urine is what is needed), Sodium, Magnesium, Potassium, Calcium, and basically any other metal, it neutralizes the Chlorine Gas.
In fact, we use chlorine to melt ice and to kill bacteria in our pools.
Sodium Chloride (a solid) is found in Ice Melt.
