[SOLVED] an AP chem free response (please help!) i have a final tomorrow (yea i was procrasinating) and i have to figure out how to do these practice problems! please help you can! i need to know how to do it ASAP! NH3(aq) + H20(l) <---> NH4+(aq) + OH-(aq) In aqueous solution, ammonia...

I'm in standard physics junior year of high school. I really like physics but am wondering if I'll be able to handle AP without pre-calculus (which I'm taking next year also).

A billiard ball has mass M, radius R and moment of inertia about the center of mass Ic=2/5MR^2. The ball is struck by a cue stick along a horiontal line through the ball's center of mass so that the ball initially slides with a velocity Vo. As the ball moves across the table (which has a...

Hi, thank you so much for making this kind of post for students like me. I have tried the quesotins but i want to make sure that i was right. if worng, please correct me. THANK YOU SO MUCH. Also i had attached pictures of the question to give you enough information. PLEASE REFER TO THE PICTURE...

Hi, I need help with my AP Physics questions. I tried all the problems and was unsure of my ways to approach the problems. If you can correct my errors, I would greatly appreciate your help. Thank you! Please answer each question and tell me whether it is right and show me how to do it and...

I am reviewing AP chemical equations in class and we have to figure out the products given the reactants. I don't want to post every single question so could someone explain how to these types of questions in general: potassuium permanganate solution is added to oxalic acid and acidified with...

Hello! My first time on here but having massive troubles with my AP Chemistry homework and need help. I have a question that gives four different reactions and I am asked to calculate the (delta)H for each of them. I am given no more information. I am not sure how to go about the problem...

Some one please check my lab report for me if it sound right (this is the first two section of my lab report). It had to be in third person pt of view, and written in passive voice. Plz give me any suggestions, or background of Cu and I, or wording of the intro. and procedure. They CANNOT be...

Please help me w/ the 2 redox equations. Show me how to assign the oxidation # and how to do it please, especially the 1st problem. The problems are attached. Thank you very much for ur time.

I'm doing an independent study in AP Physics, and am having a lot of trouble with the following problem: "To stop a car, first you require a certain reaction time to begin braking; then the car slows under the constant braking deceleration. Suppose that the total distance moved by your car...

Hi, I'm in AP Calculus and I feel really stupid :( I feel really stupid because it's only the first week of school and I'm struggling with the review (I forgot a lot over the summer) I'm posed with these two problems (in addition to many other but I don't want to bore you all :))...

Someone please give me a good explanation on how to "Balance Oxidation- Reduction Equations." Plz show me the steps and an example of how to do this type of equations. Thanks a lot.

Should AP Physics questions go under K-12 or college level? I mean we use a college textbook so I am assuming the material matches that of some colleges - but we are still in a high school setting.

I'm going to be a high school senior next year and am planning on majoring in physics at college, unfortuantely our school does not offer an AP Physics course, they only offer one general physics course which I have already taken and which failed to teach me anything. But, since I am majoring in...

hi.. my summer assignment for AP Physics is to write a three page paper describing the 'Principles of Physics', and to make a video that properly displays them to go along with it... i am having the hardest time finding the principles.. everytime i search i get links to college courses or...

Hi, I'm new here so I'm not sure how formal this should be: I have studied electromagnetism in my Physics AP class at my high school but I have had a question at the back of my head. I don't have a very good physics teacher, and he was unable to explain this to me. My question is why, when...

Hey...Im taking the Physics B test in May and I was wondering if anyone that has taken it has any advice...Just general advice on time management or how you thought the test was (easy, hard?) Thanks in advance for any comments!
