The Periodic Table

12:05 AM

So I plan on tryout for my middle school science olympiad team. I have read through physics, chemistry and biology high school books. The problem is that in chemistry the naming systems, some of the laws and reactions tend to be hard to remember. I was wondering whether it is necessary for me to complete it, or will my basic knowledge(lewis dot, molecular formula, structural formula, periodic table, etc) suffice. And if any of you have time, will basic knowledge in newtonian mechanics also be fine?

@genius It entirely depends on where you live, but it's highly unlikely to get a tough nomenclature question.

Since that would be unscientific.

The scientist shouldn't be challenged by naming, but by the puzzles the nature throws at him.

It generates different avatars for different sizes when it only should be taking the hash into account.

WHY?

DEAD

@Martin-マーチン The 'let us' might give the wrong impression that you're using the verb as the main verb of the matrix clause, transitively.

"Let's" is better.

Martin - マーチン

What?

DEAD

It might give that impression, since the question is asked by a community member, not a mod.

Like me asking for a feature request.

And that would imply that this is still not taking place, while it is.

I did not major in English, I don't understand.

@Martin-マーチン I think the distinction DEAD was trying to make was that 'let us' implies were asking someone to give us something a la 'let us have some cake' as opposed to 'let's' which is more akin to us deciding to do something between us 'let's have cake'

Grammatically there shouldn't be a difference given that let's is just a contraction, but in spoken english there does seem to be a difference in meaning. At least to a Brit.

ahhh thanks. i do understand now :D

Yeah, it's more or less what NotHoffward said.

Q: I want know the mechanism

How can I solve reaction mechanism problems of organic chemistry in a easy way? How can to convert cyclo pantene ring in to benzen ?

I guess I shouldn't read old nomenclature answers, or at least I shouldn't follow links.

Please note that your link contains several mistakes. In particular, the numbering in the following examples is wrong: 4-methyl-1-ethylidenecyclohexane should be 1-ethylidene-4-methylcyclohexane, 6-methyl-3-methylenecyclohex-1-ene should be 3-methyl-6-methylidenecyclohex-1-ene, 1-methyl-3-(4-methylpent-3-ynyl)cyclohexa-1,3-diene should be 1-methyl-3-(4-methylpent-2-yn-1-yl)cyclohexa-1,3-diene, 4-(2,2-dimethylcycloprop-1-enyl)-6-isopropylcyclooct-1-yne should be 4-(3,3-dimethylcycloprop-1-en-1-yl)-6-(propan-2-yl)cyclooct-‌1-yne, 4,4-dimethylnon-8-en-1-yne should be 6,6-dimethylnon-1-en-8-yne, … — Loong 10 mins ago

I understand that by adding Nitrogen to my water my Lucerne plants will grow better. Firtsly, is this correct? Secondly, if so, I further understand that I must add/mix Ammonia (NH3) and nitric acid (HNO3) to form nitrogen which is added to the water, is this correct? However I understand that th...

However, sometimes I make a minor correction, which bumps up the question, which gives the original author some reputation and a silver badge. :-)

DEAD

@Mithoron I think they figured out that they know the chemical formulas, and got all mad-scientist-y.

Next step, taking over the world.

@DEAD Nah they'll blow themselves and that'll be the end of story :D

Or dissolve.

No it's not. It's an advanced question, but heck, my organcis professor often gave homework questions we couldn't solve with the help of his assistants & doctoral candidates. Plus it's posed in a lazy, offhanded way, without even a question mark, and no hint to any own effort by the OP. — Karl 17 mins ago

I might respond to this, and I might not.

Just throwing it here so you guys say what you want to.
