W24 Paper 36 Last Minute Exam Tips #0 Too last minute, I am running out of time, what can I skip??

Summary

In this video, the speaker reviews the common experiments likely to appear in the chemistry exam (Paper Tre) on October 1, 2024. They discuss the chances of specific experiments reappearing, including ometric titration, enthalpy change, water displacement, thermal decomposition, and rate of reaction. The speaker recommends focusing on water displacement, thermal decomposition, and rate of reaction, as these are more likely to appear. Titration has a 50% chance of being included, while enthalpy change is considered less likely. Students are advised to prepare accordingly for the upcoming exam.

Takeaways

• 😀 Focus on experiments that have higher chances of appearing in Paper Tre exams.
• 😀 Titration has appeared frequently in previous exams, but it’s a 50% chance of reappearing in the next exam.
• 😀 Enthalpy change is unlikely to come out in Paper Tre again, so it can be skipped in preparation.
• 😀 For Paper 36, prioritize the following experiments: water displacement, thermal decomposition, and rate of reaction experiments.
• 😀 Water displacement requires setting up a water trough with an inverted measuring cylinder.
• 😀 Thermal decomposition experiments involve using a crucible and heating substances to observe decomposition.
• 😀 Rate of reaction experiments involve measuring reaction times to the nearest second through multiple trials.
• 😀 The likelihood of experiments from previous variants reappearing is lower, but titration is still a potential option.
• 😀 It’s important to focus preparation on experiments that involve practical setup and time-based measurements.
• 😀 Good luck for the exam, and remember to prioritize the most likely experiments over others.

Q & A

Which experiments are expected to appear in the upcoming Paper TRE exam?

The experiments expected to appear in the upcoming Paper TRE exam include water displacement, thermal decomposition, and rate of reaction experiments.

What is the setup required for the water displacement experiment?

The water displacement experiment requires setting up a water trough with an inverted measuring cylinder.

What type of chemical experiment is involved in the thermal decomposition experiment?

The thermal decomposition experiment involves using a substance that decomposes when heated, typically involving a chemical reaction that breaks down a compound into simpler substances.

How should the rate of reaction experiment be conducted?

The rate of reaction experiment should involve conducting a series of tests to measure the time it takes for reactions to occur, with the time being recorded to the nearest second.

What is the likelihood of titration appearing in Paper TRE?

Titration has a 50/50 chance of appearing in Paper TRE, meaning it could either appear or be excluded.

What should students prioritize in their preparation for Paper TRE?

Students should prioritize water displacement, thermal decomposition, and rate of reaction experiments in their preparation for Paper TRE.

Which experiment is less likely to appear in Paper TRE based on past patterns?

The enthalpy change experiment is less likely to appear again in Paper TRE based on previous patterns.

Why should students focus on the three recommended experiments rather than titration?

Students should focus on the three recommended experiments (water displacement, thermal decomposition, and rate of reaction) because these are more likely to appear in the upcoming Paper TRE, while titration has uncertain chances.

How accurate does the timing need to be in the rate of reaction experiment?

The timing in the rate of reaction experiment should be accurate to the nearest second.

What is the importance of focusing on water displacement, thermal decomposition, and rate of reaction experiments?

Focusing on water displacement, thermal decomposition, and rate of reaction experiments is important because they are the most likely to appear in the upcoming exam, based on current trends.
