The post-lab questions provided are SIMILAR to questions you may encounter in your lab manual. These questions will provide you with a step-by-step guide on how we approached the problem. You can use this guide and the data you recorded to help answer the questions. Any given examples with values will be with mock values. Use of these values will almost assuredly give you nonsensical calculations. They are only meant to illustrate the logic.

 

question 1

You are asked to balance and complete some reactions.

Using data from your data sheet (link) and your knowledge of the periodic table trends (link), answer these questions based reactivity and your observations. Then, balance the equations. You can also “google” many these reactions to check your answers. However, it is important to understand since these information may show up on quizzes.

question 2

Asks you to locate which part of the periodic table have strong oxidizing agents.

Understand that oxidizing agents GET REDUCED and GAINS ELECTRONS by OXIDIZING OTHERS. Using your knowledge of the periodic table trends (link), you should understand electron affinity and electronegativity trends. This will help you answer which elements are the strongest oxidizing agents. Be sure to answer clearly and specify increase or decrease, location, direction, and also specify the group.

 

question 3

Given a nonmetal oxide (CO2) reacts with a metal oxide (CaO) to make CaCO3, you are asked if boric oxide would react the same with (CO2).

Locate these elements on the periodic table. See if they are the same type and group. Understand that those in the same group behave very similarly.
