YOUR QUESTION: I'm reading "Wuthering Heights" for English, and if there is someone who can explain somethings to me, it would be great! Thanks!


Do you have specific questions? Without specific questions, it seems more like you're hoping for someone to do your homework for you rather than looking for help. Is there something in particular you're struggling with? Is it specific words? A plot device? A metaphor?

Listing some of the things you're confused on here will mean people can actually help answer your questions and help you understand. ;3


I was hoping someone would PM me and I could barrage them with my questions, because I have a lot.

For example, why is Heathcliff so volatile? Actually, why is everyone from Wuthering Heights so volatile? Why are they so rude and mean? Also, why with the repetition of names? Catharine Earnshaw vs. Catharine Linton?

TYPE OF QUESTION: Chemistry
YOUR QUESTION: How can you work out molecular formulae of compounds? Just the steps: thank you!


I don't know the steps exactly, but it helps to work out how many bonds each atom can have. eg carbon can have 4 bonds, hydrogen can make only 1 bond. oxygen can make 2 bonds*. From this you can work out that CO2 is made of two double bonds to each oxygen. Also it helps to know your functional groups and naming conventions, (meth, eth, but, prop, pent, hex...that's all I had to know during school). So if you are asked to draw the molecule (this will help to visualise it and to count the number of atoms in the compount) pentanol. You then know it has 5 carbons and an -OH group (as this indicates an alcohol). Then hydrogen bonds with all the other spots on the carbons left.

This is linked to the number of electron in the outer shell compared to the maximum for that shell. Carbon has 4 gaps, hydrogen only 1 and oxygen has two gaps and nitrogen has 3 gaps. So elements in the same period will bond in similar ways.

Sorry if I have made this too complicated.

Thanks for the clarification! I'm bumping this in case you haven't gotten a PM yet. I would suggest talking to your teacher also and seeing if they'll discuss with your or suggest some things to think about/look into.

This doesn't sound like something we can help you with. The slogan sounds like something you should come up with on your own. Us providing an answer could be cheating.

My suggestion for this is to think about yourself and how you feel about sports. You probably have or had required PE classes. What did you like about them? What did you not? Did you notice people being left out? What kind of comments were made towards them?
For the slogan, maybe look up catchy brand slogans (for fast food, insurance, etc. - if you watch commercials, you see these all the time). What resonates with you in a slogan? Music/a tone, rhyming, humor? Go with one of those and make your slogan based off that.

This is hard because we can't ask for private information and the answer to your question could depend on your academic level. An example might be nice, just for clarification.

Like, are you asking about how to tell the formula when you're given something like "dihydrogen monoxide"?

Chemistry has some pretty strict naming nomenclature. It's got specific words for number of molecules. Ex. above "di" means two and "mono" means one, so you know you have 2 hydrogens and 1 oxygen (H2O - water). Suffixes can tell you the same thing. Ex -ide vs -ate (-ide commonly referring to a nonmetallic/electromagnetic compound, meaning unless otherwise specified, there's probably not an oxygen attached to he element ending in -ide; -ate commonly indicates a salt or acid, and acid meaning it's probably going to have oxygen attached).

Tbh, if you don't know these rules, figuring out the compound of a formula is extremely difficult. I would personally just google it. =p

Sorry if I have made this too complicated.

Just gonna jump in here and add that in case you're not that far in chemistry, one of the more important things to remember is that an atom wants to have exactly eight electrons in its outermost shell (Except for Hydrogen and Helium, they only need two because they have a smaller outermost shell).
Here's an example for you:
Sodium has one outermost electron. To have a full eight, it wants to lose that one so that the next layer down, which already has eight, will be its outermost layer.
Chlorine has seven outermost electrons. To have a full eight, it wants to gain one more.
I'm sure you may recognize this compound (NaCl) as being table salt. These elements bond very often because both help the other ensure that their outermost layers have eight electrons in them. You'll also notice that elements with only one electron in that outermost layer (Sodium being one - they're called the Alkali metals) react very violently to try to fill that layer. You may have seen videos on youtube or perhaps an example in class of sodium or other alkali metals, such as potassium and francium, being put in water. If not, I'd recommend taking a quick look on youtube. It's pretty cool.

Sorry, kind of went off on a tangent there, but I hope this was somewhat helpful.

oh yeah I forgot about that. Thisdoesn't apply to the transistion metals as their sublevels have lower energies than other ones and its a tad complicated
Found alkali metals reacting with water, loved watching brainiac in chemistry class when I was in school!

TYPE OF QUESTION: Math
YOUR QUESTION: Mrs. smith's class planted 1200 pea plants. Due to a lack of water, 2/3 of the plants died. How many of these plants died?

It seems like an easy question, but it has me and my sister stumped for some reason?
I'm thinking it's 800, but I can't back this up. My sister was asking help with her homework.
