Cool Chemical Reactions

This blog is going to be about the article on the 10 most amazing Chemical Reactions. I am going to explain which chemical reaction is an actual chemical reaction and which one is not because not every member of the list is an actual chemical reaction. Then I will provide balanced chemical equations for the actual chemical reactions, including the type of reaction involved which is decomposition, combustion, etc. Finally I will choose my favorite chemical reaction from the author’s list and why I liked it over the others.

1.The chemical reaction beginning at the bottom of the list is a chemical reaction due to a change in color but this doesn’t help when color changes are also present in both chemical and physical changes. We can’t figure out a chemical equation because there weren’t any specific chemicals given.

2. The next reaction going up the list is also a chemical reaction due to its smoke and fire which would cause this chemical reaction to be a single replacement metathesis and is also redox: Fe2O3 + 2Al = Al2O3 + 2Fe

3. This reaction which includes superfluid helium isn’t a chemical reaction, because phase changes, like gas to liquid, aren’t chemical changes.

4. In this reaction there isn’t two chemicals involved just the sulfur hexaflouride which results in this also not being a chemical change.

5. In this next reaction, superabsorbent polymers (also known as hydrogels) is not a chemical reaction because the water would remain water when soaked up and the hydrogels would remain the same as well.

6. This also is not a chemical reaction because sodium acetate remains the same even t

7. This isn’t a chemical reaction either due to the fact that there is no indicator other than the change in temperature; there was no gas produced or color change.

8. This is a chemical reaction because gas is produced due to the fact that something is burning. This is known as a combustion reaction as well with a balanced equation of 6KClO3 + C6H12O6 = 6KCl + 6H2O + 6CO2 + 3O2

9. This is also a chemical reaction because again there is something burning which in this case is the magnesium and that shows it is a chemical reaction because gas is produced. This is known as a single replacement metathesis with a balanced equation of 2Mg + CO2 = 2MgO + C

10. This is also a chemical reaction that is again similar to reactions 8 and 9. There is clearly a gas being produced and something new is being created which indicates that it is indeed a chemical reaction. This is also synthesis and redox with a balanced equation of  2Na + Cl2 = 2NaCl.

My favorite chemical reaction had to be the Potassium Chlorate and Candy Reaction (Number 8) because it is a very dramatic display of a chemical reaction! It was mentioned that it was a disinfectant and included in fireworks and explosives. It really caught my attention because I didn’t realize how the combination of a simple piece of candy and some potassium chlorate could cause such an explosive and electrifying reaction. “When potassium chlorate is heated to melting point, any item added to it will cause a rapid disintegration in the form of an explosion”.

3 Questions Blog- 4/25/2014

1. What tasks have you completed recently?

Recently, I have studied for and taken the ACT a couple of weeks ago and finally received my results of a 25 overall for my first time. In English, I have taken a vocabulary final and I have finished writing a personal narrative essay on my passion as a cheerleaders. Also for English, I have been continuing to read The Picture of Dorian Gray and have completed many ID writings and discussions to have a further understanding of the book. In chemistry, we have been practicing a lot with net ionic equations, oxidation, and reduction equations which I’ve completed notes and worksheets on in order to prepare for the upcoming test. In culinary, I have recently prepared and served an Italian themed luncheon for the staff as part of my culinary final. 

2. What have you learned recently?

I have learned that by the end of the year we are all just tired of school and start to slack off but then more and more work is being crammed and piled in at the very end of the semesters. I have stressed myself out recently trying to stay on top of everything so I have learned that you need to stay on top no matter what because as it nears the end of the school year there isn’t much you can do to save your grade anymore.

3. What are you planning on doing next?

I am planning on trying to become more organized and to pay attention as much as I can now that it is at the end of the school year. This is a time of stress and racing to get things turned in and I am going to study for all upcoming tests especially my AP US history test coming up in a few weeks.


Solutions Mini Lab

Today in chemistry we made solutions out of sugar/water and salt/water. A solution is known as a homogeneous mixture of two or more pure substances. These next two compounds make up the solution and that would be solute and solvents: A solute is what is being dissolved, and a solvent is what is dissolving the solute. For example, to make a solution of salt water, you would take salt, which would be the solute, and water, which would be the solvent. The solvent is usually in the most abundance and the solute is in the least. For our experiment we created a solution of salt water and a solution of sugar which made the water the solute and the salt and sugar the solvents. Just by looking at our solutions there was no way to tell which one was which so in order to figure this out we had go back to the basics and work our way up. We began with the clarification that salt which is NaCl was indeed an ionic compound while the sugar sucrose which is C12H22O11, was not an ionic compound. We used a light bulb with metal prongs attached to it and stuck the prongs into the solutions, to find that saltwater conducted and made the light bulb glow but the sugar water or the deionized water didn’t conduct the electricity to light the bulb.



We hypothesized that the salt itself must break down into individual Na+ and Cl ions which would explain why it would conduct electricity if the current was passed through it. This also showed that the sugar water and deionized water wouldn’t conduct electricity. This experiment introduced us to electrolytes and nonelectrolytes. Electrolytes are known as substances that dissociates into ions when dissolved in water and nonelectolytes are substances that dissolve but don’t dissociate into ions when it does so.


The above picture shows that you can create a particle diagram of a sodium chloride solution and a sugar solution. The sodium chloride solution would have water surrounding it evenly and due to opposites attract the water has a partial charge so the hydrogen will be facing the Cl but will be turned away from the Na because hydrogen is positive. The sugar solution will have the hydrogen facing away from the molecules because of the partial charge and will also have water surrounding a bunch of molecules.

Chemical Reactions Lab

Today in Chemistry we performed a lab that had 11 different experiments that had to be performed to show us the different types of chemical reactions that occur. There are three major indicators that tell us if they are true chemical reactions, which include: a precipitate forming, color change and the appearance of bubble/fizzing. During each mini lab at least one of each indicators was seen, for example me and my partner performed reactions 5 and 8 which was assigned to us by our teacher. Reaction number 5 resulted in turning a milky white, became increasingly hot and had big bubbles that kept fizzing out and in reaction number 8 it turned a bright yellow color. I believe that the products of reactants can be predicted because the atoms in the reactants are the same, so the outcome will always be the same.The reactions were divided up into five sections: Section 1 (Reactions 1 and 2); Section 2 (Reactions 3 and 4); Section 3 (Reactions 5 and 6); Section 4 (Reactions 7, 8 and 9); and Section 5 (Reactions 10 and 11).

This was done based on similarity:

Section 1: Two reactants that produced one product.  Ex: 4Fe+302=2Fe203                                                                                           Section 2: One reactant that produced two or more products.  Ex: 2H202=2H20+02                                                                                 Section 3: One element or ion is replaced by another element/ion in a compound.  Ex: Zn+Pb(NO3)2=Pb+Zn(NO3)2                               Section 4: Two compounds exchanged their elements/ions for those of the other compound.  Ex: Pb(NO3)2+2KI=2KNO3+PbI2               Section 5: Combustion. Ex: CH4+O2=CO2+2H2O

Here are the balanced chemical equations for the 11 chemical reactions:

1. 4Fe(s) + 3O2(g) –> 2Fe2O3(s)

2. CaO(s) + H2O(l) –> Ca(OH)2(aq)

3. 2H2O2(l) —MnO2–> 2H2O(l) + O2(g)

4. 2NaHCO3(s) –> H2O(l) + Na2CO3(s) + CO2(g)

5. Ca(s) + 2H2O –> H2(g) + Ca(OH)2(aq)

6. Zn(s) + Pb(NO3)2(aq) –> Pb(s) + Zn(NO3)2(aq)

7. Na2CO3(aq) + Ba(NO3)2(aq) –> 2NaNO3(aq) + BaCO3(s)

8. Pb(NO3)2(aq) + 2KI(aq) –> 2KNO3(aq) + PbI2(s)

9. CaCO3(s) + 2HCl(aq) –> CO2(g) + H2O(l) + CaCl2(aq)

10. CH4(g) + 2O2(g) –> CO2(g) + 2H2O(g)

11. 4C2H5O2(l) + 9O2(g) –> 8CO2(g) + 10H2O(g)


 Ca(s) + 2H2O –> H2(g) + Ca(OH)2(aq)


Pb(NO3)2(aq) + 2KI(aq) –> 2KNO3(aq) + PbI2(s)

3 Questions Blog-4/11/14

1. What tasks have you completed recently?

Recently, I have planned out all my classes for next year in order to make sure I am on the right path and will allow me to succeed. I have also taken the ACT test this Saturday for college! In my chemistry class we have completed our test about stoichiometry and limiting reactants.

2. What have you learned recently?

I have learned that studying is very essential and will help you so much when it comes to tests, my studying prepared me for my ACT test and my chemistry test. Also I have learned that it’s okay to make mistakes as long as you learn from them and really try hard to re correct your error.

3. What are you planning on doing next?

I am planning on staying on top of all my school assignments, test and activities in order to achieve my goal of having all A’s in all my classes by the end of this year. I am also going to complete all my National Honors Society volunteer hours by committing my time to the Soup Kitchen and recycling days at school.

White Powder and Unknown Liquid

Yesterday and today in my chemistry class we did a mini lab that experimented with the reactions of combined white powders and unknown liquids to release a gas. We performed three different tests with three different combinations together. The first test we did was with vinegar and sodium bicarbonate which resulted in lots of fizzing and bubbling; creates gas. We used 0.78 grams of sodium bicarbonate and 2 fingers of vinegar which resulted in the production of 0.37 grams of gas. Test number one and two had the result of always being a 1:1 molar ratio which means for every 1 mole of powder used, there should be one mole of gas produced. For test number three is not like the other two because we had to balance the equation by putting a 2 in front of the NaHCO3 and the CO2 which had caused it to become a 2:2 molar ratio. There is a molar relationship between these two substances because you can always determine the amount of gas produced by certain amounts of solid, which is known as the line of best fine, if you have the balanced equations and molar masses. A solid to gas ratio would apply to any and/or all chemical reactions because the only factor in the ratio of gas produced is the type of solid in the reaction. This experiment overall was a very efficient way to help us learn the lesson of the mole and to be introduced to stoichiometry.
