Question:
a. Write two half-equations for the following reactions. For each half-equation state whether oxidation or reduction is occurring.
i. Cl2 + 2I– → I2 + 2Cl–
ii. 2Mg + O2 → 2MgO
iii. 4Fe + 3O2 → 2Fe2O3
b. Zinc metal reacts with IO3-ions in acidic solution. Construct a balanced ionic equation for this reaction, using the two half-equations below:
2IO3- +12H+ + 10e– → I2 + 6H2O
Zn → Zn2+ + 2e–

I have been a tutor for the past 5 years. I have experience working with students in a variety of subject areas, including computer science, math, science, English, and history. I have also worked with students of all ages, from elementary school to college. In addition to my tutoring experience, I have a degree in education from a top university. This has given me a strong foundation in child development and learning theories, which I use to inform my tutoring practices.
I am patient and adaptable, and I work to create a positive and supportive learning environment for my students. I believe that all students have the ability to succeed, and it is my job to help them find and develop their strengths. I am confident in my ability to tutor students and help them achieve their academic goals.
