Homework 1 16:36 ONE     Read through and study the following worked out example carefully. Once  you believe you understand it, answer the question at the bottom and then.  proceed to complete in order questions 2 through 4 on your homework.  Question:  Rank the following acids in order of increasing (weakest to strongest)  acid strength.  HCl, HI, HF  Solution:  Step 1:  All of the acids listed above are binary because they contain only  hydrogen and 1 other type of element.  Step 2:  Since all of the acids listed above are binary they are ranked in strength  based on the size of their anions. Each anion has a parent element that you can  find on the periodic table. The closer to the bottom and further left on the periodic  table that parent element is, the larger it is. We must first identify what the anion  is in each acid, and what period its parent element is located in on the periodic  table. We do not have to worry about the group number because all of the parent  elements of these anions are in the same in group on the periodic table.  Acid: HCl Anion: Cl -  Parent Element of Anion: Cl  Period of Parent Element: 3  Acid: HI Anion: I -  Parent Element of Anion: I  Period of Parent Element: 5  Acid: HF Anion: F -  Parent Element of Anion: F  Period of Parent Element: 2  Step 3 : The acid which the largest anion is the strongest, and the acid with the  smallest anion is weakest. The period number of the parent element of anion is  directly related to its size because all of the parent elements of the anions are in  the same group on the periodic table. The larger the period number the larger the  size of the anion. Based on that information the following correct ranking is  obtained.  HF < HCl < HI  According to the information presented in the example above, what is the name  of the weakest acid?

TWO     The following problem is similar to the example you just studied, but you  are now responsible for solving step 3 on your own. Read through and  study steps 1 and 2 carefully. Once you believe you understand it, provide  an answer for step 3 by completing the question at the bottom. Then  proceed to homework questions 3 and 4.   Question:  Rank the following acids in order of increasing (weakest to strongest)  acid strength.  H 2 S, H 2 Te, H 2 Solution:  Step 1:  All of the acids listed above are binary because they contain only  hydrogen and 1 other type of element.  Step 2:  Since all of the acids listed above are binary they are ranked in strength  based on the size of their anions. Each anion has a parent element that you can

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
