I recommend to use AP U.S history crash course
The Good:
This book is helpful when getting into some last minute studying. It is not geared towards giving you a comprehensive view of AP US History. Instead, it specifically focuses on the tips for being successful with the test. A “crash course” is just the right description for this book. It helps you avoid getting caught up in the monotony of facts and information that won’t actually be on the test.
The makers of this book have analyzed the newest version of the APUSH course and exam outline to give you just the information you need. Besides that, it includes some pretty helpful test-taking tips and strategies. It will help you think about how to approach both the multiple-choice sections and the essay portions.
One of the unique features included in this review book is the online practice exam. This exam features instant feedback as well as an explanation of answers. Having self-assessment helps you see how much further you have to go before you are really prepared for the APUSH exam. These practice tests can really serve as a guide for the rest of your studying.
The Bad:
This book is a trimmed down version of the AP US History course. That means it does not cover all of the details you could learn in class or read in other books. It is a review book without any fluff, which can make it harder to find general overview information about themes and big ideas. Even with these issues in mind, this is still one of the best APUSH review books out there.
The reaction between ethanol C2H5OH and water H2O is a chemical reaction and is exothermic.
Option A is correct.
<h3>What is a chemical reaction?</h3>
A chemical reaction is a rearrangement between the ions and molecules of a substance. For a chemical reaction to take place, bonds are broken in the reactants and new bonds are formed in the products.
The chemical reaction between ethanol and water is;
- This reaction is exothermic because molecules move from a higher state of energy to lower states.
- The resulting volume is also lesser than the initial volumes of the reactants according to Henry's Law, showing that heat is given off to the walls of the container.
Therefore, we can conclude that A chemical reaction occurs, as evidenced by the volume of the resultant mixture being less than the total volume of the initial components.
