Question 1

What should I focus on for International Baccalaureate Organisation Alternative Academic Qualification Chemistry?

Accepted Answer

In Paper 2 data-response questions, always annotate given data with relevant formulas before attempting calculations, and show all working to maximise partial credit even if the final answer is incorrect.

Question 2

What should I focus on for International Baccalaureate Organisation Alternative Academic Qualification Chemistry? (2)

Accepted Answer

For the Internal Assessment, explicitly address safety, ethical, and environmental considerations in your methodology, as these are distinct marking criteria in the exploration section.

Question 3

What should I focus on for International Baccalaureate Organisation Alternative Academic Qualification Chemistry? (3)

Accepted Answer

Always show full workings for calculations, including units; even if the final answer is incorrect, method marks can be awarded.

Question 4

What should I focus on for International Baccalaureate Organisation Alternative Academic Qualification Chemistry? (4)

Accepted Answer

Use precise scientific vocabulary (e.g., 'endothermic' vs. 'exothermic', 'electrophile' vs. 'nucleophile') to demonstrate depth of understanding.

Question 5

What should I focus on for International Baccalaureate Organisation Alternative Academic Qualification Chemistry? (5)

Accepted Answer

For data analysis questions, annotate graphs clearly and comment on uncertainties, using error bars or percentage differences where appropriate.

Question 6

What are common mistakes in International Baccalaureate Organisation Alternative Academic Qualification Chemistry?

Accepted Answer

Students frequently confuse the terms 'atom' and 'molecule', especially when describing diatomic elements or ionic compounds, leading to inaccurate representations in equations and diagrams.

Question 7

What are common mistakes in International Baccalaureate Organisation Alternative Academic Qualification Chemistry? (2)

Accepted Answer

A common misconception is that adding a catalyst increases the yield of a reversible reaction, when it only speeds up attainment of equilibrium without shifting its position.

Question 8

What are common mistakes in International Baccalaureate Organisation Alternative Academic Qualification Chemistry? (3)

Accepted Answer

Errors in sign conventions for thermodynamic quantities—such as misassigning positive or negative values for enthalpy changes in exothermic/endothermic processes—lead to incorrect numerical results and faulty predictions.
