  3. Create a study schedule: Set aside dedicated study time each week to ensure you're making consistent progress.

General HESI Chemistry Study Tips

  • Find a study partner: Do you have a colleague, classmate, or friend who is also pursuing a HESI Chemistry certification? Studying with a partner can help keep you accountable and provide an opportunity for discussion and clarification. Practicing test questions together might be an opportunity for some friendly competition too!

  • Take breaks: Regular breaks can help prevent burnout and improve retention of information. As you study, give yourself regular pauses to decompress and process what you are learning.

  • Stay organized: Keep your notes, study materials, and practice exams organized to avoid feeling overwhelmed. Whether you prefer a physical or digital studying environment (for instance, taking notes by hand versus typing them into your Notes app), a tidy space and methodical approach will help you stay focused on your test prep.

  • Take care of your physical health: A healthy body leads to a healthy mind, so make sure your test prep routine also prioritizes exercise, nutrition, and sleep during your study period. During the lead-up to your HESI Chemistry test day, don't cram - get plenty of rest so your brain is sharp!

  • Utilize test-taking strategies: Techniques, like the process of elimination, can help improve your chances of success. If you are stuck on a difficult practice exam question, try to rule out one or two options to narrow down the possible answer. Exam Edge's test-taking system allows you to flag practice test questions you want to return to - use these features to your advantage!
By incorporating these study tips into your preparation process, you will be well on your way to success with the HESI Chemistry exam. Remember, success requires dedication and hard work - don't give up!

HESI Chemistry - Study Plan Tips Sample Questions

If an industry is draining very hot water into a river, what could happen to the river water?

Correct Answer:
a. the amount of the dissolved oxygen will reduce in the river water.


when an industry discharges very hot water into a river, it can significantly alter the river's ecosystem. one of the primary effects of this thermal pollution is the reduction in the amount of dissolved oxygen in the water. warmer water has a lower capacity to hold oxygen compared to colder water. consequently, as the temperature of the river water increases due to the input of hot water, the solubility of oxygen decreases. this reduction in dissolved oxygen can have detrimental effects on aquatic life, particularly for species that have high oxygen requirements.

many industries, including power plants, require large quantities of water for cooling and other processes and often use nearby rivers as a convenient source and discharge point. after using the water, the heated water is often returned to the river. this practice leads to an increase in the river's temperature, known as thermal pollution. elevated water temperatures can lead to various ecological imbalances. for instance, certain aquatic species may not survive at higher temperatures, which can reduce biodiversity in the river. additionally, the altered conditions may favor certain invasive species that thrive at higher temperatures, further disrupting the native ecosystem.

moreover, the decrease in dissolved oxygen due to higher water temperatures affects more than just the respiratory health of aquatic animals. it can also influence the rate of photosynthesis in aquatic plants and the biochemical cycles within the river ecosystem. lower oxygen levels can increase the vulnerability of certain species to disease and reduce their reproductive capabilities, which can have cascading effects throughout the food chain.

in conclusion, the discharge of hot water into rivers can lead to a significant reduction in dissolved oxygen levels, amongst other ecological impacts. this not only endangers the existing aquatic life but can also lead to long-term detrimental changes to the river's biodiversity and overall health.
