Introduction

This book follows the Platform Adaptable Strategic Solution (PASS) template designed by Drs. Lindsay Blackstock, Sharon Brewer, and Verena Roberts to support students at various levels of understanding and mimic the experience that a student may have during an office hour. You can find the first examples using this template on the PASS Chem website: https://chempass.opened.ca/.

For each question, students may attempt and check their answer with Show/Hide Answer. If you were correct, AMAZING! You can move on to the next question.

Strategy Map: If you need assistance in what general steps to take (i.e., spoiler-free! ) then move on to the strategy map (see the yellow box below). The strategy map will provide you with a procedure (instructions) of what to do to reach the answer. 

Solution: If you would like to see each step (i.e., spoiler alert!), move on to the solution (see the green box below). This section shows a simple step-by-step solution to reach the answer but without any commentary.

Guided Solution: If you need more help and want to know why you are performing each step in the solution, move on to the guided solution (see the blue box below).

The guided solution explains the chemistry theory or rationale behind the process. The guided solution’s purpose is to replicate what a student may experience during an office hour or a lecture, working through a problem supported by the ‘teacher talk.’ Here, you will also find hints embedded throughout, including:

• Links to read more from the LibreTexts reference textbooks
• Additional context or an alternative perspective
• Reminders about various unit conversions or significant figures
• Common mistakes to avoid

Complete Solution: Below the guided solution is the complete solution that combines the step-by-step solution with the key context points from the guided solution.

Check Your Work: In chemistry, you can often avoid mistakes by thinking critically about the theory related to the problem and predicting what the answer should or shouldn’t be. Be sure to check your work (see the purple box below). This section provides the rationale of why your answer ‘makes sense’ with respect to the chemistry theory. Use this strategy to avoid making mistakes in similar problems.

Question 

The creators of this Pressbook currently use the free open LibreTexts platform CHEM1500: Chemical Bonding and Organic Chemistry to host their remixed General Chemistry textbook for Thompson Rivers University (TRU). Each topic will have a question that we will be working through together. Clicking on ‘Show/Hide Answer‘ below will only reveal the answer. 

Our suggested approach:

1. Attempt it yourself. Check to see if you need additional assistance to get the correct answer.
2. After checking your answer, decide how much additional support you need to understand how to solve the problem yourself. Navigate to one of the three boxes below:
   1. Strategy Map
      
   2. Solution
   3. Guided Solution.
      The boxes are listed in order of how much assistance is provided from least to most.

Below the answer is the link to the online resource to find supplementary information about this topic.
