This Assessment Task is designed to assess your understanding of topics 1-7 (Weeks 1 & 2 Lectures) presented in this unit. This assessment requires you to apply concepts presented in lectures and tutorials to determine the answers for a series of multiple-choice questions.

The quiz is not timed and you are allowed two attempts. The highest score of the two attempts will be recorded.

Note: Quiz questions are generated randomly and you will receive different questions on subsequent attempts.

All questions are of equal weighting. One mark will be awarded for each correct response. Incorrect responses will not incur a penalty.

Assessment 2 - Calculations and Short Answer Questions, has been designed to assess your comprehension of the concepts presented in the unit through their application to answer a series of questions. This assessment relates to Weeks 3-6 Lectures and Tutorial contents, and Study Guide topics 8-14. All workings must be provided for answers to calculation questions. Inclusion of correct units and chemical notation is expected. Short answer questions may require you to explain, reason, describe, analyse, or evaluate information and provide an appropriately detailed written response. Marks will be awarded for each question as indicated in the Assessment 2 - Questions Document which will be available on the CHEM11043 Moodle site. The Assessment 2 will be available on the Moodle site  from Week 5, starting Monday, 1 April, 2024. 

Maximum marks available for each question will be indicated in the Assessment 2 Written Assessment (Question document), which will be available on the CHEM11043 Moodle site. Marks will be awarded for each question or partial question as indicated in Assessment 2. No marks will be given for incorrect answers, incorrect units, or explanations.

Assessment 3 Practical Assessment consists of two (2) online laboratory quizzes and the competencies at the residential school:

1. Laboratory Quiz 1: Laboratory Introduction Safety and Spectroscopy.
2. Laboratory Quiz 2: pH and Titrations.

These laboratory quizzes will be available on the Moodle site for students to access from 2 May 2024 to 24 May 2024.

The practical component of CHEM11043 has been designed to provide and scaffold essential laboratory skills in chemistry for 2nd and 3rd year chemistry units and the workplace. The practical skills and associated theory for CHEM11043 will be supported with eight (8) laboratory sessions. Assessment 3 will be graded as Pass/Fail. In order to Pass, students must achieve a "Pass" grade for the practical component.

The practical sessions will be undertaken in a four-day residential school. The experiments have been designed to allow you to develop excellence in laboratory practices and provide a solid foundation for future laboratory work. During the practical sessions, you will develop skills in the following: • Working safely in the laboratory • Correctly using top pan and analytical balances • Sample preparation including quantitative transfers • Correctly using pipettes and volumetric flasks • Preparing dilution series for spectroscopic analysis • Using a spectrophotometer • Graphing techniques with consideration of interpolation and extrapolation • Performing relevant calculations to process data from spectroscopic analysis • Correctly using a burette • Calibrating a pH meter • Choosing an appropriate indicator for a neutralisation reaction titration • Conducting titrations with good technique and accuracy • Performing relevant calculations to process titration data • Maintaining data records

All students are required to attend and participate in all laboratory exercises scheduled for the four-day residential school. The specific assessment criteria for components of this task are as follows:

1. Laboratory notebook must show records of laboratory data, calculations and completion of discussion questions. Instructors will inspect notebooks randomly throughout the course of the residential schools.
2. Two online practical laboratory quizzes must be completed during the unit. The quizzes will relate to associated theory and techniques used in the two blocks of practicals (spectrophotometric and titration focused). You will have unlimited attempts to complete each quiz. However, to pass this assessment, you are required to achieve a "Pass" grade for the practical component.
3. Demonstration of competency in specific laboratory skills is required. This includes the correct usage of burettes, volumetric flasks, pipettes, balances, and pH meters, which will be assessed during the laboratory sessions.

This assessment will cover content you have studied throughout this term. It will be presented in a written format accessible via the Moodle site during Week 12, with a 48-hour time window for assessment access. It is essential to attempt and submit your work within a 9-hour period after downloading the assessment questions file. Ensure your completed Assessment 3 - Final Term Assessment is uploaded to the Moodle site in the form of a Microsoft Word document.

When completing this assessment, please take note of the following:

• Attempt all questions.
• All submissions should be typed and saved as a Microsoft Word document.
• Display all calculations and detailed workings as required.
• Chemical reactions should undergo balancing
• Provide correct units for your answers.
• The completed assessment is to be submitted via upload on the Moodle site as a Microsoft Word document only.

The breakdown of topics to be covered in Assessment 3 will be made available on the Moodle site prior to the Assessment 3 date. 

Marks will be awarded for each question or partial question as indicated in Assessment 4 (Question document), available on the CHEM11043 Moodle site. No marks will be given for incorrect answers, formulas, explanations, organic nomenclatures, or incorrect organic structures.
