Having trouble with homework? Come here and ask. If anyone knows the answer, or can help, please post here and help, you will recieve thanks, and if this thread becomes popular and important, you might be acknowledged by a moderator and given a merit. This is a good idea that I came up with while working on my chemistry homework (MgBr2= wtf?) so... yeah, if you need help, or can give help, please post your questions or answers, and a simple rule, please try not to post more than five (5) problems in one post, and please don't double, triple, quadruple, or multi-post. I hope your questions will be successfully answered and that you have great acadmic success, also, if you are past school or college, you can still help, if you've gone through the grade that problem is in, you will have better experience dealing with it.
Ah, the horrible days of homework. I still have them! I'm in 8th grade, but take Algebra, and Pre-AP Language Arts. So, if you need any help on most things, feel free to ask.
You use your periodic table to help yourself figure out the charges of nonmetals and group Ia and IIa metals. There really isn't an easy way to remember the transition metals unfortunately. Group 1a: 1+ Group 2a: 2+ Group 3a: 3+ Group 4a: 4+ Group 5a: 3- Group 6a: 2- Group 7a: 1- Group 8a: None, inert Now look at AlCl, Aluminum chloride. Al has a 3+ charge, since it is in group 3a, while Cl has a 1- charge, because it is in group 7a. Since the compound must be neutral, the correct formula should be AlCl3, or a ratio thereof.
are the 1a, 2a, etc. the rows across or rows down?
oh thank you for telling him that, but he really should find the link to the original thread instead of saying that there is another one already made.
Wasn't that exactly what I was saying???
Btw, anyone having trouble with understanding a certain word, try googling it. Most come up with a few results for definitions. This is what I have to do every so often when talking with Strop...
I am only in 7th grade but I am in an advanced math class so if it would help I know a lot about algebra or I could help those who are younger than 13.
ok, can people PLEASE ask questions, it doesn't even have to be homework, I have a dictionary right next to me at all times if you want to learn the definition of a word.
@ Cenere find someone other than me to help, and _S_K_E_, pi is an infinite decimal sequence, it CAN'T be divided, or multiplied, or added, or subtracted. also, x is a variable and could be any number, unless x is simplified, the "equation" cannot be worked out.
