Chemistry help??? It's simple stuff...?
You prepare a salad using a garden salad mix and an oil and vinegar salad dressing. If you suddenly decide that you don't want oil and vinegar on your salad, what would you do to separate the salad dressing from the garden salad mix?
I cant understand chemistry at all?
First , I think embets is right . The things that he said was you should do everyday . Second , because of your exams are coming up I suggest you can make it simple, you can think of it as something else . Third , formulas to compile a it down . Fourth , discuss your questions with your classmates , talk them why you confused , and how you think of this question . I have encountered the same problem, the above is my solution. I hope it help . ~Don't worry ! If you have tried , God might bless you .~ : )
Why chemistry is so boring?
haha.. although it is a matter of perspective, it really isn’t boring!This Article can help you with this:https://educrafterm.school.blog/...https://educrafterm.school.blog/No subject is boring in itself, its just a matter of perception and presentation of that subject. If it is explained in a good way, you will love that subject and if it is explained in a bad way, you will hate that subject.Sometimes, it is not Chemistry’s fault, its the person teaching at fault ;)Thats all for the philosophical part! Now, I can share some tips, that actually help you embrace chemistry..Try a new perception. Chemistry is the subject which provides you with many fundamental reasons for the existence of this universe. Here, you don’t see ‘what happens next’, rather you find ‘why did this happen’. Well what do your think astronauts are looking for on Mars after discovering water availability……Think!First things first! Get your basics and fundamentals right. (You must know Co is Cobalt not Copper!) .. Get those valencies and nomenclature right before digging in!Secondly, write, write and write. If you find the Chemistry teacher in front of you a nosy annoying character frightening you to the highest ….. pin it down! Write all what she says, take down as much as you can. Now you managed to subside your frustration and you have an excellent set of notes to study from.Thirdly, Try relating examples. I’ll take an example of ‘Corrosion’. Instead of studying about its theory and all the 250 pages of notes I had.. (woof!) . I took up an example. (For instance the Bridge Collapsing. )Lastly, duh! Revise!TIP: Most of us have pictorial memory. Try searching the web for some images for reactions you need to memorize. Try drawing the structures all the other way round.I followed this patter to score in this:Take notes — Revise– Practice — Revise Reactions — Clear Doubts — Revisit the Topic (Skim through notes)Yes, chemistry is done majorly through rote method. But why to be prejudiced…. Try these methods yourself! They worked for me, they’ll work for you too.After all, chemistry isn’t as boring as you think!To Know more, Click Below:https://educrafterm.school.blog/...https://educrafterm.school.blog/Hope this Helps.
Chemistry is killing me. could someone please help me with these?
Um...we need to know how much vinegar and what you were reacting it with (which chemical, also its mass, if a solid, or volume & concentration, if a solution) to be able to help you!! Added: You don't say much about the lab, I am having to assume you are doing some kind of titration; neutralizing the acetic acid in the vinegar with a basic solution. Take the volume of titrant (basic solution) IN LITERS required to neutralize the vinegar x the molarity, this will give moles of titrant. If this titrant reacts with just one mole of acetic acid (such as NaOH), the moles of titrant = moles of acetic acid in the vinegar sample. Now that we know the moles of acetic acid that were present in the vinegar, we can determine the molarity of the vinegar, but only if we know the volume of the vinegar sample used. As for the sample size, it isn't important, but it is! Let me explain. You can use a large or small sample of vinegar for the titration and you will use correspondingly more or less of the titrant, and the moles of acetic acid will be more or less, but, when you divide by the larger or smaller sample volume, the molarity will turn out the same regardless of sample size! Maybe when the teacher said the volume is not important, he/she meant the exact sample size isn't important (like it doesn't need to be exactly 10ml or something like that, but you did need to write down the volume you used). The volume of the sample is needed to calculate the molarity of the vinegar, as molarity is moles/liters and if we don't have the liters we can't calculate molarity. It is possible they you are doing some other type of experiment where molarity is determined in a different manner, so some of this may not apply to your situation. However, if you were supposed to have recorded the volume of vinegar used and didn't, maybe you can get the molarity of the vinegar from another student that took the same lab and work backwards and find out what volume of vinegar would have reacted with the volume of titrant you used. This might be considered cheating, but IMO to be able to fabricate the experimental data from the answer requires just as much of an understanding of the concepts as doing it the right way!
Physics or Chemistry??? Which one is better? HELP Please?
Well this is my last year of highschool and I have two choices Physics or Chemistry and I don't really know which one would be more fun and better for my future!!! So I don't know people. Please tell me the advantages and disadvantages of this 2 courses!!! Thank You !!!
Help with some chemistry problems....please help?
Prefix multipliers are things like 'milli', 'micro', 'nano' and so on. You should have a table of them somewhere, or be able to google them pretty easily. Nano is 10^-9, so the answer to question 1 would be 5.81 nanolitres (nL) Giga is 10^9, so the answer to question 3 is 67 gigajoules GJ Make sure you pay attention to the case - capital or lowercase - when you write these out. I'll leave the rest for you to do. For the conversion questions, in the first one you need to divide 1000 by 60 to convert from minutes to seconds (i.e. the object will travel 60 times less far in a second than it does in a minute.) The conversion from kilometres to miles is about 1.6, though you might want to google for a more precise value. For the final question, a cm^3 and a mL are the same unit, so no conversion needed on the bottom line, but there are 100 micrograms in a gram... Hang in there!
How do I gain an interest in chemistry?
Interest will come only when you are curious about something which you are interested in. Same applies for chemistry also. So stay curious first. Below are something you can do 1. You should know this first. Chemistry plays an important role in our daily life more than other subjects. It Starts from your tooth paste in the morning to ends at the sleeping tablet which somebody use to sleep at night. So ask yourself where you are using chemistry in your daily life. This will help you to stay more curious about chemistry.2. Try to understand the basic concepts first. Because no way you can do experiments without some proper basics. If you want to do just a labor job then you can do experiments in lab from whatever the procedures which professors give it to you. Following the experimental procedures without thinking is complete wasting of your time and its sometimes dangerous too. Start from an atom and think yourself that how atom plays a role for making a molecule. Similarly go step by step with other topics. Please don't just memorize the concepts and organic reactions as many students do for their exams. If you do that then all will evaporates from your mind faster than liquid nitrogen. For basics I strongly recommend this book. When you read this book you will come to know the essence of chemistry rather than just reading.3. Another important thing is that the teacher who teach you the chemistry subject. Because some of the teachers makes chemistry subject to be bored. In that case you can't do do anything but if u really curious still you can learn many basics from online resources like youtube etc...Here is the one guy who makes chemistry more interesting than others. I hope he is good role model not only chemistry teachers but also those who teaches science. Try to watch it.Tyler DeWitt4. Again think, think, think whatever you read and see about chemistry. Ask questions by yourself how it works and how its related to other things in chemistry. Try to find out the answers for it. Eventually you will get into chemistry.

Boyfriend says no chemistry, what does that mean?
I was just reading the answers--think some detail is necessary.. we have lots to talk about--we talk all the time our likes and dislikes, religious beliefs, political beliefs are all almost the same (about 90%) we rarely fight, but have good discussion. When he says chemistry he always relates it to the physical, but he says I am attractive. As for finding someone else. Most likely not, with his work schedule it would be difficult. (except on line). He has also had the chance to go be physically with someone else and turned it down. I guess. Thanks for all the answers. They are really helping me think things through.
Wts the best way to understand physics ?
spend more time on physics and chemistry and less time on the other two. And READ READ READ
