A monatomic ideal gas with volume 0.200 L is rapidly compressed, so the process can be considered adiabatic. If the gas is initially at 1.01x10^5 Pa and 3.00x10^2 K and the final temperature is 477 K, find the work done by the gas on the environment, Wenv.

I get 30.9 J when I do it, but the book says the answer is -17.9 J. Please explain how to get the right answer.

When I was in high school (about 7 or 8 years ago) I read a series of Christian books. They were for young adults/teens and I remember that they were about a brother and sister. Their dad had gone missing on a missions trip I think and when they had trouble, they chatted online with this man who gave them advise (I never finished the series, but I had always assumed that this man would be revealed to be their dad). The one I remember the best was that a new-age book store had opened in town and the teens' mom was gone for the weekend. The lady at the book store asked for their help because she knew they were christians to deal with a house that had demon activity. I think several of the books deal with spiritual warfare, but I cannot remember any of the titles, the name of the series, or the author. Any help would be appreciated.

I have been working on this for hours and still feel like I have no idea what is going on. Please explain how I can get the answer too. I need to understand this. Thanks!

Suppose exactly 25.00 mL of water was pipetted into a flask containing 25.00 mL of a stock solution of a weak monoprotic acid. The solution was titrated with 0.1025 M NaOH(aq). Estimate the equivalence point volume from the data below. Calculate the molarity of the acid solution (total volume=50.00 mL).

Volume of NaOH added pH

28.40 mL 5.05

28.50 5.22

28.60 5.49

28.70 6.40

28.80 10.06

28.90 10.40

29.00 10.58

29.10 10.71

29.20 10.81

For about the past 2 weeks I have have had the persistent tight feeling in both of my legs (and the sides of my feet) like they are about to cramp up (like when you get a charlie horse). I didn't do any rigorous exercise at the time or recall anything unusual that may have caused it. Walking or moving my legs seems to help but when I am sitting still or trying to sleep, I can feel it. It is very uncomfortable, and almost pulsing sometimes. When I was little, I would get very bad leg cramps at night that would prevent me from walking for several hours and felt worse than breaking a bone, so the constant feeling like that is about to happen, although it hasn't actually happened, is very scary. I'm 22, so I really don't know what it could be, but it is really affecting my sleep because I keep waking up and having to walk for a few minutes before I can fall back asleep. If you have any suggestions of what it might be or how I could stop it, I would really appreciate it!

This is the question I don't know how to do. Please explain how you get your answer so I can learn how to do it. Thanks!

Calculate the volume of concentrated HCl needed to prepare 250 mL of an HCl solution that is approximately 0.12 M

I live in Indiana and I applied (and paid) for a substitute teaching license on July 24th. When I check the status of the application it says "school material review" and classes for the students start tomorrow so I would like to be able to start soon. I have emailed the LVIS and haven't heard back. I was just wondering if it is normal to wait this long for a license?

Long story short, One of those gel filled stress balls exploded on my wood dresser sometime during the night and then a zen garden spilled on top of the gooey mess. The sand made the gooey gel harden like glue and I can't figure out how to get it off.

I have a little cabin that the fish can swim through for my aquarium but my sister accidentally washed it with dish soap, is there any way I can make it safe for my fish again?

I woke up this morning feeling a little bit uncomfortable. At first I thought it was just some leftover emotions from a dream I had been having about work( of course work is uncomfortable), but then my stomach started to gradually start hurting. It hurt below my belly button, like when you have diarrhea, and also above it, like when you throw up. I went to the bathroom and was unable to have a bowel movement at first, and the pain just kept getting worse and worse. Finally I had diarrhea and also vomited, even though I hadn't eaten anything since the night before( So i just vomited stomach acid). This pain didn't feel like the flu at all, I could probably say that it was the worse pain I have ever felt. Even before I threw up, my ears were burning up and pulsing and my scalp itched really bad. Usually when I am sick vomiting or having diarrhea will lessen the pain, but with this pain, there was no relief at all. I finally couldn't produce any more vomit or diarrhea and curled up in my bed in the fetal position after checking my temperature (and taking pepto and ibuprofen). My temp read 96.6 even though I felt like I was burning up. I still had no relief from the pain, until I started rubbing my stomach in a circular motion. This gave me about 15 seconds of partial relief every 2 minutes or so. This went on for about an hour until I felt comfortable enough to fall asleep. When I woke up after another hour, I felt much better except my whole abdomen felt tight and compressed, which is how I felt for the rest of the day. I have also not been able to produce a bowel movement since then. My mom says it's just the flu and I don't need to see a doctor, but I thought I'd look for a second opinion.

The question is

f(r)=√r+1 -9 The r+1 is the only part under the square root. the -9 is outside.

solve for f(x-1)

Me and my friend Anna have been friends for years, we were best friends all through high school. The kind of friends that are completely open with each other and even if we got mad, we forgave the other right away because our friendship was too important to risk over an argument. We even stayed really close after graduation, and got together almost every week even going to college 2 hours away. but now Anna has gotten a new boyfriend that I don't like that she thinks she is going to marry and she has gotten a new job at a gas station and has started to change for the worse. She is getting deeper and deeper into some really bad stuff and doesn't want to talk to me about it. In fact, I'm not sure I even want to talk to her anymore either. She seems like a completely different person and It's like she forgot everything we have been through together. I feel like I am the only one trying to keep us friends anymore, and I'm wondering if I should just give up?

I don't know if maybe i'm doing something wrong on the website, but I really hope i am. I need to ship an Easter gift to a friend. We are both in Indiana and my package is small and only weighs about a pound. I tried both ups and usps and both of them came to between 20 and 25 dollars for the cheapest shipping options. I am not going to spend 25 dollars to ship a 5 dollar gift, but I don't know why it's so expensive. Someone please help me out.

I am working on an art project that is due tomorrow and the color sharpie I need only came in fine point. I need to write with it, so I need an ultra fine point and was wondering if anybody knows of a way to maybe adjust the tip with common household supplies so that it works like an ultra fine point.

So, I went to Florida(fort myers area) for vacation and found a lizard, I think he is a gecko, but I don't know what kind. I kept him in a tank and need to know what kind he is to know how to care for him ( unless they all require the same care) I cant get a picture of him because he is too fast, but he is light brown, like dead grass and he has two darker brown wavy stripes going down either side of his back. he is about 2-3 inches long with his tale and his tale takes up most of that. Right now I'm treating him like a leopard gecko, but I want to take care of him correctly.

All I have in my tank are guppies, four females, one male and a few 1 month olds that i haven't sexed yet. One of my females just gave birth to about 12 fry and I usually take the fry out and put them into another tank so that they don't get eaten. I already have a pretty full tank and was just wondering how many fry I could expect to survive into adulthood if I just leave them alone? I have six fake plants and two live plants in my tank along with an aquarium decoration that has hiding places inside. oh, and it's a 20 gallon tank.

Ok, so here is the dream:

I was outside my apartment building( I don't have an apartment in real life) watching about 100 kids playing on a playground. Me and two of my friends were babysitting them, but one of my friends was in the car listening to the radio. Suddenly he came over and told us that a huge storm was coming that would destroy the world. We quickly gathered the children and I announced that the safest place for us all would be inside my apartment. When we reached the apartment, I not only had all of the kids, but everyone in the world was trying to crowed into my apartment. Just as we are going in, ominous looking clouds roll in from every direction and we get a torrential downpour of snow, rain, sleet, hail, and fire with a bunch of tornadoes. Suddenly we get a huge earthquake and everyone passes out. When I wake up, I find that my computer is broken beyond repair and when I actually stand up, I see that the floor is covered with multicolored grains of rice. I soon realize that this rice is almost everyone in the world just shrunk really tiny. Myself and about 50 others are still normal size. I try to find my friends and accidentally step on some of the tiny people. I don't seem to really be that worried about stepping on them though, more like I don't want to get them on my shoes. I find some of the other full sized people and tell them to go to the theatre so they don't miss the show( because the apartment is now a huge mansion) I pull out my phone and try to text one of my friends, but the letters are mixed up and it is very frustrating. finally I get a txt typed out and my phone dies. This is where I wake up. Just curious if it means anything!

I would like to eventually open up a small pet shop selling small rodents, fish, and reptiles. I was researching the possibility, but came up with absolutely nothing when I searched for pet vendors. Do these places just not have websites, or do other pet stores supply their own pets. Where do the animals come from?

My little sister is 14 and I remember when I was her age I would read 3 books a week. Reading was very important to me, but my sister hates reading, she won't even read her school books and It kills me to see anyone, especially my sister, living without that joy that I have with books. I have tried buying her books but they just collect dust. I've tried reading to her but she zones me out. I have tried getting her interested in a book by telling her about it, or having her watch the movie, but she acts like it is the most boring thing in the world. I need to find a way to convince her of the joy of reading?

Lately, I have begun to have this strange feeling, I'm not even sure it's an emotion, but it has the same feeling as one. It is difficult to describe but It feels like a longing, mixed with an ominous feeling( like when you know something bad is about to happen in a movie) mixed with seriousness mixed with innocence. It's feels very good, but the kind of good when you know it is wrong. I usually get it when I'm outside or when I see trees, and it makes me think of blackbirds. I know this sounds bizarre, but I'm being entirely serious and would like serious answers. What is this feeling and why am I getting it?

Just two days ago, I had a very pregnant guppy in a small breeding "box" the kind where the babies can swim to the bottom to escape the mother, but overnight the pregnant guppy just went back to her normal size and shape without any babies. She was very far along so I don't think she could have absorbed them, and she was definitely pregnant, so I don't know what is going on?
