Answers - midterm study guide. Test Difficulty:.Adding stress to the left side increases the rate of the forward reaction, creating more products. The hydroxide and conjugate acid ions are created in a ratio and therefore will be equal.

Therefore, atom Z will be farthest to the right have the most protonsand thus will have the highest electronegativity value.

Twice as many moles being created means twice as many electrons are needed. With a lower concentration on the reactants side and a higher concentration on the products side, the reaction will shift left, decreasing the overall potential of the reaction.

This is true for both A and Bmeaning [NO] would decrease. The only tricky bit here it to remember that boron is considered stable with only six electrons in its valence shell. Additionally, they would have a greater spread of potential velocities, which would lead to a wider curve. Thus, oxygen has a higher electronegativity. Converting each of those to moles yields 0. Thus, for every one oxygen atom there are three carbon atoms and six hydrogen atoms.

Unit 1 - Chapters 1,2,3 - Summer Review

The first equivalence point occurs at a volume of 10 mL, and thus the half-equivalence point is at a volume of 5 mL. If the nitrogen is reduced, that value must get more negative.

Option B has a strong acid and strong base, option C has a strong acid and its salt, and option D has a weak acid and a weak base.

An increase in temperature thus causes a shift to the left, decreasing the numerator and increasing the denominator in the equilibrium expression. However, the overall mixture will have a greater mass Of the four options, methanol and acetone would both have dipoles, but those of methanol would be significantly stronger due to the H-bonding. To balance the electrons, the reduction half-reaction must be multiplied by two and the oxidation half-reaction must be multiplied by three in order to have six electrons on each side.

The nitrate ion is a spectator and would not appear in the net ionic equation. During this time, the speed of the molecules and thus the temperature does not rise. The oxygen is in excess, and only 2. Prior to the reaction there were If the molecules are moving very slowly, the IMFs between them are more likely to cause deviations from ideal behavior. A low dissociation is signified by a low presence of hydrogen ions. The weakest acid is choice C.

A higher bond order means shorter and stronger bonds. Through mass spectrometry, it is proven that each element has more than one possible mass. In a larger flask, the gas molecules will spread farther apart and become more disordered.

When identifying line I vs. The rate of both the forward and reverse reactions are constant at equilibrium. If the temperature does not change, neither does the equilibrium constant. Eventually, the reaction would reach equilibrium again, meaning the lines would level out.

As the line is curved, the only way to do that without calculus is to draw a line tangent to the curve at that point and measure its slope. To get the overall order, we add the exponents in the rate law. When creating solutions with acid, you always add some water first, as the process is extremely exothermic and the water will absorb the generated heat.

The entropy disorder of the system is increasing as it moves from three gas molecules to five.Advanced Placement AP. It can be difficult to keep your notes organized throughout the school year, especially in a class that covers so much content. This article will give you links to notes on every topic included in the AP Chemistry curriculum. If you're missing some of your notes, or if you just want a more structured overview of what you need to know for the exam, you've come to the right place!

I'll also give you some study tips so that you can use both these notes and the notes you took throughout the year to your best advantage. Due to the COVID coronavirus pandemic, AP tests will now be held remotely, and information about how that will work is still evolving. The notes in this article can be used to study smaller portions of the curriculum or to review for the final AP Chemistry exam.

As of the updates, there are nine units that organize all the concepts in the course, so I've categorized these notes according to that framework. Topics should be listed in roughly the same order as you learned them in class.

These notes will provide a ton of background information, but keep in mind that AP Chemistry is less about memorization of facts and more about the ability to apply your knowledge to a variety of experimental scenarios.

Reading notes can only get you so far. Practice problems are essential a point that I will emphasize again later in this article.

Take a diagnostic test before you dive into these notes if you plan on using them to review for the full AP test. Based on your results, you can see which areas need the most improvement, and then you can focus on the notes that are most relevant. These notes come from several sources. Some of are in-depth, others give a broad overview.

Some focus more on notes, others on working through practice questions. The goal is to give you a comprehensive guide of what you need to know for AP Chemistry. Note that, because AP Chemistry's curricula was recently updated inmost online notes haven't been updated yet, which is why some topics don't have corresponding notes and some notes cover multiple topics.

At the end, I've also included a link to a document created by a high school AP Chemistry teacher that goes through all of the concepts in one place. This document was created by an AP Chemistry teacher. It's sort of like a long crib sheet with all the concepts and formulas you need to know in one place!

If you want a quick holistic review without going through every individual notes page listed above, you can take a look at this document to remind yourself of the most important concepts for each unit. Ah, the bliss of knowledge. Also, this guy should probably get to the ER immediately.

AP Chemistry Practice Midterm Exam

This is what happens when you cram, everyone. If you want to use these notes to your full advantage, you shouldn't just read them all and consider yourself prepared. For chemistry, you need to dig deeper to understand the material fully. Here are some tips to keep in mind:. If you're studying for chemistry, you should work your way through concepts in the order of when they show up in the curriculum.

You need to master the basics first, or more advanced problems will look like complete gibberish to you. If there are any topics in Big Idea 1 that you don't feel comfortable with, start your studying with those. Everything else in the course builds on the concepts you learned in the first couple of months! Every time you read a set of notes, do a few practice problems to make sure you've absorbed the information.

Reading through these notes is a waste of time if they don't provide you with the background information and skills you need to solve relevant problems. If you find that you're having trouble with practice problems after you read through notes, this should be a red flag that you need to modify your study strategy. Don't forget about the notes you took in class, handouts your teacher gave to you, and any other resources you've accumulated throughout the year.

It's worthwhile to shop around and see whether certain explanations of concepts resonate more than others. You might decide that videos explaining concepts are more useful to you than notes, or you may choose to buy a review book that provides more guidance in planning out your studying.Show all questions.

Essential Knowledge Top of Page One cannot count particles directly while performing laboratory work. Thus, there must be a connection between the masses of substances reacting and the actual number of particles undergoing chemical changes. Expressing the mass of an individual atom or molecule in an atomic mass units amu is useful because the average mass in amu of 1 particle atom or molecule or formula unit of a substance will always be numerically equal to the molar mass of that substance in grams.

Thus, there is a quantitative connection between the mass of a substance and the number of particles that substance contains. The mass spectrum of a sample containing a single element can be used to determine the identity of the isotopes of that element and the relative abundance of each isotope in nature. The average atomic mass of an element can be estimated from the weighted average of the isotopic masses using the mass of each isotope and its relative abundance.Which one of the following represents an acceptable possible set of quantum numbers in the order n, l, ml, ms for an electron in an atom?
