welcomes

no one follows this account but here I am again. I haven't logged in for about a year. I'm senior this year stuck at home struggling with my productivity and whatnot. I figured maybe using this account would give me structure so here I am again. I'll probably just rant a lot and look at other people's pretty journals and spreads but its something more positive than where my mind has been I suppose.

Happy to be back,

nectar

ap chem terms

hey yall

I’ve been meaning to make some ap chem flashcards the problem is my teacher never really gave us a list of terms or words we needed to know, and then from there graphs and whatnot if anyone has some examples they can show me or maybe a quizlet I could take a look at I’d be eternally grateful. If anything I might just end up using the terms in the glossary or something

#ap chem #ap chemistry #college board #ap exam #testing season #study tips #study help #flashcards #quizlet #terms #lots of questions

B. Stoichiometry

Ionic and molecular species present in chemical systems: net ionic equations

Balancing of equations including those for redox reactions

Mass and volume relations with emphasis on the mole concept, including empirical formulas and limiting reactants

C. Equilibrium

Concept of dynamic equilibrium, physical and chemical; Le Chatelier’s principle; equilibrium constants

Quantitative treatment

a. Equilibrium constants for gaseous reactions: Kp, Kc

b. Equilibrium constants for reactions in solution

Constants for acids and bases; pK; pH

Solubility product constants and their application to precipitation and the dissolution of slightly soluble compounds

Common ion effect; buffers; hydrolysis

D. Kinetics

Concept of rate of reaction

Use of experimental data and graphical analysis to determine reactant order, rate constants, and reaction rate laws

Effect of temperature change on rates

E. Thermodynamics

State functions

First law: change in enthalpy; heat of formation; heat of reaction; Hess’s law; heats of vaporization and fusion; calorimetry

Second law: entropy; free energy of formation; free energy of reaction; dependence of change in free energy on enthalpy and entropy changes

Relationship of change in free energy to equilibrium constants and electrode potentials

IV. Descriptive Chemistry (10-15%)

Knowledge of specific facts of chemistry is essential for an understanding of principles and concepts. These descriptive facts, including the chemistry involved in environmental and societal issues, should not be isolated from the principles being studied but should be taught throughout the course to illustrate and illuminate the principles. The following areas should be covered:

A. Chemical reactivity and products of chemical reactions

B. Relationships in the periodic table: horizontal, vertical, and diagonal with examples from alkali metals, alkaline earth metals, halogens, and the first series of transition elements

C. Introduction to organic chemistry: hydrocarbons and functional groups (structure, nomenclature, chemical properties). Physical and chemical properties of simple organic compounds should also be included as exemplary material for the study of other areas such as bonding, equilibria involving weak acids, kinetics, colligative properties, and stoichiometric determinations of empirical and molecular formulas.

V. Laboratory (5-10%)

The differences between college chemistry and the usual secondary school chemistry course are especially evident in the laboratory work. The AP Chemistry Exam includes some questions based on experiences and skills students acquire in the laboratory: making observations of chemical reactions and substances; recording data; calculating and interpreting results based on the quantitative data obtained; and communicating effectively the results of experimental work.

Colleges have reported that some AP candidates, while doing well on the exam, have been at a serious disadvantage because of inadequate laboratory experience. Meaningful laboratory work is important in fulfilling the requirements of a college-level course of a laboratory science and in preparing a student for sophomore-level chemistry courses in college.

Because chemistry professors at some institutions ask to see a record of the laboratory work done by an AP student before making a decision about granting credit, placement, or both, in the chemistry program, students should keep reports of their laboratory work that can be readily reviewed.

Chemical Calculations

The following list summarizes types of problems either explicitly or implicitly included in the topic outline. Attention should be given to significant figures, precision of measured values, and the use of logarithmic and exponential relationships. Critical analysis of the reasonableness of results is to be encouraged.

A. Percentage composition

B. Empirical and molecular formulas from experimental data

C. Molar masses from gas density, freezing-point, and boiling-point measurements

D. Gas laws, including the ideal gas law, Dalton’s law, and Graham’s law

E. Stoichiometric relations using the concept of the mole; titration calculations

F. Mole fractions; molar and molal solutions

G. Faraday’s law of electrolysis

H. Equilibrium constants and their applications, including their use for simultaneous equilibria

I. Standard electrode potentials and their use; Nernst equation

J. Thermodynamic and thermochemical calculations

K. Kinetics calculations

omg yes please don’t forget i know that even i will have to constantly remind myself

things you need to hear this exam season

- don’t beat yourself up for struggling even if you’re doing your best - you are smart and capable so don’t let laziness stop you from achieving your potential - stop self sabotaging. that tv show can wait. take a break but don’t become your own obstacle to success. get shit done first - eating right, staying hydrated and sleeping well are non-negotiable. look after yourself - grades do not define you so be kind to yourself. but do your best and work hard for what you want

hey there! so I’m currently taking AP US History (which is basically the bane of my existence) and I wanted to share some of the resources I’ve been using!

What I Do

-flashcards flashcards flashcards! i personally use quizlet because i don’t have to make the flashcards myself (i’m lazy i know) and i can study just about anywhere using the app

-i never ever ever use the textbook. i know, strange, but i find textbooks super overwhelming. i completely depend on my review book because it takes so much less time to read and it has everything you need to know

Online Resources

website with notes, outlines, vocab, AND supreme court cases

this teachers website even though the formatting kills me (it has flashcards and review sheets)

also that same teachers youtube (the songs are catchy)

khan academy

videos of powerpoints (its kinda like Khan Academy but you can download the powerpoints!)

if you do HAVE to use the textbook, here’s most of The Enduring Vision and here’s The American Pageant (these are pdf’s so you have to download them)

Other Resources

-the internet is a magical place with lots of stuff! there are so so so many websites and things with notes and outlines!

-review books!! there’s the Amsco book my school uses, but i have friends who swear by the Princeton review book and the Barron’s review book

good luck guys and have fun :))

ooo do you have any tips for ap calc and apush?

oh boy do ijk it’s been at least 2-3 years since i took ap classes but i sure do have some tips for you!

ap calc tips

it’s not that bad, just find as many old exams as you can and practice, practice, and practice! i know that it’s cliche, but the more you understand the format and the concepts that the ap calc wants, the easier the course will be!

heres an amazing derivative cheat sheet to help you study because derivatives and integrals are gonna be the biggest thing you need, my dude

here’s an amazing ap calculus guide / tutorial post

coping with math (math for people who aren’t good at math)

another cheat list of calculus

beyond that, i don’t really remember much about the ap calc exam, tbh?

i’d just say make sure you’re solid on terminology and stuff too!

apush tips

i nailed that thing, apush was easy af

know your dates

and for the essays and short answer stuff a lil cheat thing is to know enough information about either women (women’s events like suffrage or smth), a minority group, or something along those lines.

if you look at old exams, the prompts will always have something about these topics, so if you know enough information about them, just writing all the facts about the topics is enough that your argument doesn’t need much fleshing out bc ur bombarding them with sm information.

idk if that made any sense but it worked for me so idk lmao

apush crunch time masterpost

apush masterpost (her notes are so good, highly recommend)

apush resources

hope this helped! if you need anything else, just hmu and drop an ask in my inbox, love! xx

66 Essay Transition Phrases-

To continue an idea:

Furthermore

Moreover

In addition

As well as this

What’s more

Additionally

Regarding this

The fact that [x] is so, shows that

To compare and contrast ideas:

In comparison

In contrast

Unlike [x], [y]…

Like with [x], [y]…

Similarly

Comparatively

In the same way

Another way of viewing this is

Yet

Still

Nevertheless

On one/the other hand

Conversely

Notwithstanding

In spite of this

However

Besides

Though/Although

On the contrary

Contrary to this

In order to list:

Firstly; Secondly; Thirdly; Finally

To begin with; In addition; In conclusion

These are the following:

These are as follows:

In order to introduce an example:

An example of this is (the fact that) (the following)

To illustrate this

This is exemplified by the fact that/to exemplify (this one seems a little bit weird, but I use it all the time in order to show an idea being strengthened within a lot of my English Literature essays)

For instance

For example

In this manner

In particular

Namely

[x] can be shown strongly/most clearly when…

To show that something causes something else:

As a result

Because of this (I wouldn’t use this one in very formal writing because formal writing tends to discourage the use of ‘because’ and ‘also’ at the start of your sentences)

Consequently

Hence (this can also be used in the middle of the sentence to explain why something is the way it is)

For this reason

The consequence of this is

To repeat an idea with more/as much detail:

To repeat

That is,

In other words

To be precise

To be exact

More precisely/exactly

To reiterate

To draw conclusions:

From this, I can extrapolate (most of the time, personal pronouns are not used in very formal writing, so ‘it can be extrapolated’ is good if you want to sound very sophisticated)

From this, it can be inferred that…

It is clear that from [x], [y] means…

This shows the reader/audience that…

This enables us to understand the fact that…

[x] shows us that [y] feels…

From this, it is clear that…

To make an overall conclusion:

In conclusion

In short

To summarise

In summary

To conclude

I hope this helps!

springbreak break™️

hi its been a while and of course i have been worrying!!

i was on spring break this week and was fortunate enough to be able to go visit colleges and universities here in my state, I want to edit the clips and possibly upload them to youtube because i personally really love watching videos like that I'm gonna do some research so the video comes out somewhat nicely. the trip made me realize a couple of things that I think could help other high school students

anyways I made this post because we are in the month of may which means we are weeks away from ap testing and sat testing, for these reasons I am here to ask for tips on how to study for such big tests. I am taking AP Chem, AP English Language and Composition, AP US History, and AP Calculus AB as well as the SAT on May 4th. so far I have bought flashcards, started writing notes for APUSH and reviewing for chem and even so I feel like there's more I can do

any tips will be greatly appreciated. please and thank you!!
