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?

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?
Please be sure to validate your opinions and ideas with citations and references in APA format.

Which of the metals reacted with the most solutions?

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

1. The text of the paper must be at least 4 pages in length.
One page must contain a hand-drawn molecular structure in ink showing hybridizations and bond angles, with a list of chemical and physical properties. The last page must be a bibliography, clearly showing the references used for the paper.  Make sure journal articles are cited properly, including journal title, year, volume, number, author, article title and pages. Total length of the paper should be 4-5 pages, so that leaves 2-3 pages of actual writing.
2. Format the paper using 1-inch margins, double spacing and Times Roman 12-point font.
3. A minimum of Four (4) references is required.  Onereference must be The Merck Index, the best place to find the chemical/physical properties and a structure.
           The Merck Index link:
 https://library.shoreline.edu/MerckIndex   
 You need to log in with your Shoreline username and password to get access
4.  One must be a peer-reviewed scientific journal about your molecule from Shoreline  
database.
Two magazine articles websites (for example: the Encyclopedia of Science and   
 Technology) are a good source for current applications and information. No more than  
two websites may be used, and they must be crediblewebsites, i.e., .edu, .gov.  Wikipedia 
does not count as an acceptable reference, but it is 
 a good starting point.
​​
5.​Include the following information on your molecule, as appropriate.  Not all information will be available for all molecules, but something in each section must be present.
a.​Background: discoverer, date discovered, origin of name, source, first known use,history, developing company, etc.  
b.​Major uses or industrial importance – keep to two or three uses, how it works or achieves desired effect if applicable.
c.​Anything else of interest – here is where any unusual/unexpected uses, side effects,applications or issues discovered during your research should be presented.  This is the fun part!
​d.    ​Include on a separate page: hand-drawn structure showing hybridization and bond angles, physical and chemical properties including toxicity (if any).
6.​Treat this as an English composition.  Use complete sentences and coherent paragraphs.  Although I am not an English teacher, I will consider spelling and grammar in the grade.  It is a very good idea to make use of the Reading/Writing Center and the grammar/spell check function in Word.
7.​The paper is worth 10% of your total grade.
