Hon Chemistry 1-11-23 Double Replacement & Combustion Reactions

HON CHEMISTRY: We had to go fast, but do you realize what we did? We finished all 17 types of reactions today! We’ll practice them tomorrow since we had to go so fast today.

Careful when you work with any of these! For all single replacement reactions and reactions involving forming or decomposing oxide, be sure and refer to the Activity Series. Yes, you do get to memorize the Activity Series for the test – for the big test, not for the coming up quiz!

Are you working on memorizing all 17 types of reactions?! But don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!! (and yes, I realize I am repeating myself, but I do and you can!)

  1. When can decomposition result in no reaction? This type of reaction may have no products if the reactant is a metal oxide and the metal in the compound is above iron on the activity series. The only metal oxides that decompose in heat alone are mercury and anything below that on the activity series.

  2. What elements on the activity series are least likely to be found in nature? The elements at the top of the activity series are rarely found in nature because they are more reactive. If they were commonly found in nature, then they would be reacting with things all around them, which would not be good for the environment.

  3. Why is it a bad idea to store acids in a lead container? It is a bad idea to store acids in a lead container because lead is able to react with acids because of its location on the activity series. A container that reacts with what it is holding is not a very good container.

  4. Why can’t lithium be found free in nature? Lithium is high in the activity series meaning it reacts with both oxygen and water. If it were freely in nature, it would most likely react with its surroundings.

  5. Why do diatomic molecules react with themselves? Some elements are so reactive that if the element is on its own, it will react with itself. Some examples of what elements do this would be hydrogen, oxygen, and nitrogen.

  6. Why is pure potassium rarely, if at all found in nature? This is because potassium is very high on the activity table indicating that it is extremely reactive. Potassium in nature reacts with its surroundings quickly to form a less reactive compound.

  7. Why is something like gold which seems already rare more commonly found in nature than other pure substances on the activity series’s? Gold is low on the activity series which means to find pure gold you would have a better chance at finding gold than other pure substances, but for some substances you might be able to find variations of those substances that have already reacted.

  8. Why is lead not good to build house pipes? Lead reacts with acidic substances like human waste, and it can also cause lead poisoning for drinking water. This is because of its reactivity on the scale.

  9. Why can Chlorine not replace Fluorine in a Single Replacement Reaction? Chlorine is less reactive than Fluorine on the activity series. This means that the reactivity of chlorine will never be enough to take the place of Fluorine in a chemical rxn. In other words, fluorine is top dog.

  10. Why is a container made of something such as Tin not suitable to store acids? This is because tin is an element very likely to react with acids based on its placement on the activity series.

  11. Why can’t copper replace calcium in a single replacement chemical reaction? Copper is higher than calcium on the activity series, and in a single replacement reaction, elements can only replace other elements that are lower than them on the activity chart.

    • Why can’t copper replace calcium in a single replacement chemical reaction? Calcium is higher than copper on the activity series, and in a single replacement reaction, elements can only replace elements that are lower than them on the activity chart.

  12. How flammable are 1st-6th graders? This would be useful to know when planning out the explore zone to prevent heat blankets or even life support from having to be broken out. We done need any possible liabilities throughout the presentations.
