A student analyzed impure samples of Oxalic Acid dihydrate (mm = 126.08g) using a .128 Molarity solution of NaOH. If a .473g sample of impure acid required 35.00 mL of NaOH to reach end of titration, how many moles of Oxalic Acid Dihydrate were in original sample?

H2C204 . 2 H2O + 2 NaOH = Na2C2O4 + 4 H2O

For the reaction shown, calculate how many moles of NH3 form when each amount of reactant completely reacts.

3 N2H4(l)→4NH3(g)+N2(g)

I have multiple options to "plug in" the first is 4.7 moles of N(2)H(4)

Please explain what to do, I can't find it in my notes and the online homework site doesn't explain or help in any way it is SO FRUSTRATING.

Here's a question I cannot figure out:

The density of gold is 19.3g/mL. If you had (2.53x10^1) kilograms of gold, how many milliliters would you have?

answer must have 3 significant figures and in scientific notation.

I have a long driveway. In my dream I was walking down my driveway with my boyfriend and I looked out into my field and saw a big white horse running across it. I started saying how beautiful and amazing it was, then realized "oh that's my neighbors horse!" I didn't want it to wander near the road and get lost or hurt so I went to the end of my driveway. It came up but was very scared. I kept trying to approach it and calm it down (meanwhile my bf was telling me he wasn't sure this is a good idea) finally I was able to grab it's black harness and pet it and calm it. I walked it back to my house. In my drivewayby my house, my old bookshelf was just sitting there.. It was 2 sided though and I started looking through the drawers. Then I woke up.

f(x)=8x-x^2 (x squared)

i feel like this is so easy but i can't find how to do it!! please help

Recently I found the dirty hippie sabotage remix of Tove lo's song "habits" and it's awesome! I need more great songs!!! The song cracks by flux pavilion is good too. Someone give me a list! Please

I just need some advice. My boyfriend and I have been dating two and a half years and we used to never swear at eachother. We'd swear but never at eachother and we'd never say I hate you. We went through a 2 month phase recently where we fought non stop for hours at a time usually ending with me crying. I became more emotional and he became angrier which made fights even more common. During this time he started to hardcore curse at me. Telling me to shut the f*** up and calling me a *****. I think I hear him tell me to shut the f up at least once a day and it's usually over me just telling him something he doesn't wanna hear. Nothing mean just like saying his conversation with his brother was confusing and he'd get all pissed and swear at me. I've only sworn at him once. I know to some it may seem stupid but I grew up in a family that never swore infront of eachother. I don't mind it but when it's said to someone you're to love I feel like it's a slap in the face and disrespectful.

Sue's course grade is based on a weighted average. The weights are as follows: homework (15%), quizzes (25%), tests (40%), and final exam (20%). if Sue's homework average is 75, quiz average is 70, test average is 83, what must she score on the final exam for her course average to be between 80 and 89?

please help, I cant figure out how to tie in the % with the average.

Math is not my forte at all :( i'm starting to understand it but this question stumped me.

i mainly do not understand what to do with the 2/5. please someone explain i appreciate it so much!

I'm 19 years old and I've always been in love with tattoos. Now that I'm old enough and have some money I'd love to get some, mother inappropriate or "too much" but a couple simple ones. One being a Latin phrase on my forearm, but while discussing it with my tattoo artist he said most people in the medical field really frown on any tattoos. I'm going this fall to be an ultrasound technician. Do you really think one simple tattoo would really hinder my chances of landing a job? It's really a bummer I have to even consider this 😔 I need all opinions but please nothing rude.

One day I randomly squeezed my right breast and a tiny bit of white stuff came out. I did it again a couple times then it stopped. After a while I tried again and it did it more. It has been doing this for at least 3 months and only on my right one. I'm not pregnant I've had a regular period. What on earth could this be? I don't have a doctor at the moment. I'm 19 years old as well.

please help me, every now and then if i angle my head to my left and swallow this extreme painful shock occurs in a spot kind of above my ear on the right side of my head. It usually happens when i am working and i think if my arm is slightly raised and only when i swallow. I can barely describe it except its like a huge painful twitch thats so painful for a split second i jump. while it happens its like i black out or lose track of my vision just for a very short moment and then i regain myself almost instantly. This sensation is so scary cuz its strong and only on one part of my head. It doesn't happen too often but every now and then for the past couple years. could this be a sign of anything? im very worried now because tonight at my job it happened and it seemed even worse then usual. Im only 18 too.

His birthday is on valentines day (it sucks!) and i made him this bullet shell necklace with his initials on it in a fancy font and a black bead on the top with the little copper part used to be, then i got a teddy bear that ill probably hang the necklace on. Then i bought him a famous brand shirt for 25$. Im also taking him out to eat at a really nice italian restaurant (cuz hes italian). would that be a good gift? weve been dating almost 9 months with many more to come :] and for my birthday 2 months ago he got me a necklace and a lava lamp so it was simple. i need feedback or any other good ideas!!!

It seems like every day i get gas at some point, and if it gets bad ill get a "gas bubble" which causes a sharp pain until i manage to get all the gas out (which is extremely embarrassing and aggravating) Also, it has been 3 months since my bowels have been moving regularly, i used to have a certain time a day where id go to the bathroom and it'd come out fine and normal but lately it feels like either i have diarrhea like 3 times a week or barely anything comes out and its soft. i dont know whats wrong i dont thing its any food except ice cream in particular.. i know that makes me sick. but i can drink milk and be fine. sometimes i think cheese from pizza can get me sick but im not sure. Could this be anything in particular? Im so sick of being sick in my stomach its literally the worst. its never vomitting its always in my lower abdomen feeling like i have diarrhea or very gassy. im only 18 what is going on with my body?

im writing a short story or "gothic tale" for my american lit class and its about a girl who is put in an asylum and hallucinates to see insanity coming for her. but i need the story to end with her death, but i cant really find any good info on the internet about specific deaths within the asylums. even if she commits suicide, i have no clue where to start with it!! please help, give me any ideas you have :] thankss
