Demo’sCopper 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.

Demo’sZinc 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.

Demo’sBarium 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.

Demo’sLighting a Candle

Is a combustion reaction

Hydrocarbon+ O2(g) ---CO2 + H2O

What in the world

isn’t ChemistryThink 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.

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 !!!!!

What is ChemistryStudy of the structure of matter

Atomic or molecular properties and how it affects material properties

Study of the changes that matter undergoes (reactions)

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

ChemistryDrugs – Medication Acetaminophen and Ibuprofen

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.

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)

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.

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.
