How can we determine the relative reactivity of different metals?

Virtual Lab:  Activity Series
Background:
The usefulness of metals in structural and other applications depends on their physical and chemical
properties. Although iron is the most common metal used in manufacturing, it must be protected against
corrosion because rusts easily. Copper is used in electrical wiring because it conducts electricity extremely well and resists corrosion better than many metals. Gold is a highly valuable jewelry metal because it is essentially unreactive. How can we determine the relative reactivity of different metals?
To determine the activity of metals you can compare the reactions of metals with different
metal ions. Consider equation 1 and 2 below:
2Al(s) + 3CuCl2(aq)  –>   2AlCl3(aq) + 3Cu(s)    (Equation 1)
Cu(s)  + AlCl3(aq)     –>    No Reaction             (Equation 2)
The reaction of aluminum with copper (II) chloride (Equation 1) is classified as a single replacement reaction – aluminum reacts with and “replaces” copper ions in copper (II) chloride. Single replacement reactions will occur spontaneously in one direction only (compare Equations 1 and 2). A more active metal always replaces the ion of a less active metal. In general, the activity of a metal may be defined as follows:
An active metal will react with a compound of a less active metal, which is converted to its “free element” form. The more active metal forms a new compound containing metal cations. Based on Equation 1, aluminum is more active than copper and therefore replaces the copper (this is called a single replacement reaction).

Objective:
-To explore the reactivity of metals
-To practice writing single replacement reactions
-To practice using the activity series chart in your reference table
Procedure:
1.  Click on the link below or copy and paste it into your browser.
​teachchemistry.org/classroom-resources/metals-in-aqueous-solutions-simulation
2.  Click Activity 1.
3.  Click CONTINUE at the bottom.
4.  Pick Mg metal and click CONTINUE.
5.  Click on each beaker to see the “molecular scale”
6.  In data table 1,  if a reaction occurred, write “reaction.” If no reaction occurs write “no reaction”.
7.  In table 2, write the balanced equations for the reactions that occured.  (Hint: these are single replacement reactions)
8.  Now repeat steps 1-7 for the next three metals (Cu, Zn and Ag).
Data/Results:TABLE 1
TABLE 2
Questions:
1.  Which of the metals reacted with the most solutions?
2.  Which of the metals reacted with the fewest solutions?
3.  List the 4 Metals in order from the most reactive to the least reactive.
4.  Refer to table J in your reference table.  This is the activity series which lists the most reactive metals on top and the least reactive on the bottom.  Compare your answer to question #3 with the activity series.  Are your results in the same order?  Why?  (Click here for Table J)
5.  If we added Pb to the list, which of the solutions would you expect it to react with?
All these information above for illustration make  a report based on the youtube link https://youtu.be/VatDpKMJ-BU And the rubric

Are there specific conditions that might benefit by consuming more acidic foods or alkaline foods?

Acids and Bases
Instructions
Please complete the following steps for your discussion post and response.
Acids and bases can be found in many places including the kitchen. Acids like lemon juice can make foods taste sour. Basic or alkaline foods such as peas or almonds may have more of a bland taste.  As we’ve learned this week, an acid donates a proton and a base will accept a proton.
Choose three foods that you can find in your kitchen.
Describe how the food tastes, smells and looks.
Using this week’s resource, what is the pH of the various food you’ve consumed and how do they contribute to the acidity or alkalinity of the body-specifically discuss an organ or system in the body? You should include outside resources and cite them according to APA.
Are there specific conditions that might benefit by consuming more acidic foods or alkaline foods?

   AOL email-| +1.8O5.738.61OO |- TECHNICAL SUPPORT ̫””NUMBER Aol plans to cease

  
AOL email-| +1.8O5.738.61OO |- TECHNICAL SUPPORT ̫””NUMBER Aol plans to cease its status as “carrier-of-last-resort”. The company complains about how horrible it is to be the last choice for customers, and has began to warn builders that, if they choose to start with another company, they had better let their home buyers know that Aol won’t be available should the consumer want to make the switch.
Let me make sure I understand this: Aol is letting people who won’t care who provides the service in three years know that they are going to refuse to serve someone who actually wants them. Or, even clearer, Aol is telling consumers to shove it, we don’t have to help you.
I am interested in this for several reasons. First, my husband has worked in the telecommunications business for years before forming his own low voltage wiring company, Redd Infinity. So, although we are no longer in that field, we still maintain interest. Even better, however, I am a defunct Aol customer who, after sitting on hold with them for three hours, called Comcast on my cell phone and switched my Internet to the cable company, rather than dealing with Aol’s shoddy customer service (this came after several problems over the course of a year).
Most interesting of all, however, is my perspective as a small business owner. I concede that there are some customers we just don’t want. Chief among those are the price surfers – those who are most concerned with price (research notes that less than 10% of customers list this as most important – the rest search for quality and service). Basically, you can never make someone who cares only about the bottom line happy, and if you have tried several times – and I highly encourage you try to win them over with your superior service and products – then you may as well give up. As soon as someone underbids or undercuts you, they will be gone.
But Aol isn’t waiting to be undercut. Instead, they are taking potential customers who have no role in the decision-making process and saying, “Sorry, folks, we won’t be offering you service.” I have to tell you, if I move into a new neighborhood and the folks one block over have service, but Aol tells me they will not now or ever offer service because the builder didn’t use them – not only will I smile and say, “Great, thanks for keeping my wallet out of your grubby paws,” I will go on to tell everyone I know that Aol is exacting its revenge on the consumer. I will be persuasive. And so much the worse if I have been a long-time customer in good standing.
I understand that Aol is here to make a profit. We all are. But by pointing randomly at people and saying, “Sorry, we will never serve you, due to decisions you didn’t even make (other than choosing to buy a house in the ‘wrong’ neighborhood,” well, they make me wonder what their plans for the future are. If I were a builder, I’d start building to spite them.
In the meantime, all that worry I had about monopolies with the merger of Aol & AT&T, well, I guess they are unfound. Never mind that these small companies will have to take the leavings of whatever business they can scrounge up. Now is the time for small telecommunication companies to run to the builders with the article or letter in one hand and a plan in the other. “Let’s kick Aol where it hurts,” I’d say. As a telecommunications business owner, I’d be glad to know that Aol can’t swoop in and steal away all of my customers like they’ve done thus far. And as a builder, I’d flaunt the fact that Aol refuses to do business with my neighborhoods. Maybe put up a huge sign: “Aol doesn’t want us, and we don’t want them!”
Seriously, this provides an edge for the small phone companies. Those who move now, especially in Georgia and Florida, where the law will be taking effect, stand a chance of surviving the forthcoming monopoly wannabe. My cheers go out to the little guy – I think you can make it!
