Hey! I'm not too good at chemistry and this one problem is stumping me. How do I solve it?

If it took 23.60 mL of NaOH to neutralize 25.00 mL of 0.1110 M HCl, what is the molarity of the NaOH solution?

Thank you in advance!

Hi all! I'm really stuck on this problem. Find dy/dx implicitly for the equation xy + sin(y) = 1. Does y' = -cos(y)?

Here's what I did, but I'm pretty bad at this so it's probably wrong:

xy + sin(y) = 1

y' + cos(y) = 0

y' = -cos(y)

Okay I know this description is SUPER vague but I figure SOMEONE has to be able to help me.

I caught it on TV one day and it was a really weird movie...I don't remember it well at all but I think a lot of people at the end died. I think the people in the movie were teenagers.

The main thing I remember about the movie was this actress and that's really why I'm trying to find it. I remember she had really big lips. Her character was kind of shy and quiet at first and then she gets beat up and the only scene I remember vividly is after she's beaten up and she's laying in the bed with a busted lip and blood everywhere and she starts crying and I think she ends up dying. I /want/ to say her name is Sarah (either the character or the actress) but I'm really not sure.

I know this is super vague and I'm sorry. I think the movie is a little older, maybe late 90's or early 2000's. If you know anything that could help me, thanks in advance!

Hi, I'm only in my second year of Chinese so I don't know that much yet, haha. So basically the question explains it all. An example would be "熊猫的住的地方". Would that be okay to say? Or like... "New Orleans 有多的好玩儿的活动。" I've just never heard it before so I don't know if it's a thing.

I wrote an essay for my German class but I REALLY need someone to proofread it for me...:P I didn't know how to say a lot of things so it's probably really bad...Our guidelines were to write about our weekend, and we had to use 4 genitive prepositions (trotz, anstatt, wegen, während) and simple past, past tense, present, and future tense.

German:

Letze Wochenende ging ich mit meiner besten Freundin Sarah zu dem Kino und zu dem Zoo. Ich bin bei ihr gegangen und sie hat sich in meinem Auto gesetzt. Jedoch regnet es. Trotz des schlechten Wetters haben wir gehen bestimmen. Zuerst gingen wir zu dem Kino. Wir haben Emil und Die Detektiv ansehen bestimmen. Anstatt des Kandis haben wir Popcorn gekauft. Auch haben wir Getränke und Nachos gekauft. Während des Films habe ich gelacht. Das Film gefällt mir sehr viel! Nach dem Film sind wir zum Zoo gegangen. Das Wetter hat gut gewerden. An dem Zoo haben wir viele Tiere gesehen. Mein Lieblingstier ist das Zebra. Wegen des guten Wetters sind die Zebras draußen gewesen. Ich habe ihnen geschwenkt. Dann sind wir nach Hause gegangen. Es war jetzt viel spät. Ich habe Sarah ungearmt und dann bringe ich sie nach ihre Hause. Sarah und ich haben viel Spaß gehabt. Ich werde eine Wochenende mit Sarah wieder haben!

English (what I want it to say):

Last weekend I went with my best friend Sarah to the movies and to the zoo. I went to her house, and I picked her up with my car. However, it was raining. In spite of the bad weather, we decided to go anyway. First we went to the movies. We decided to see Emil and the Detective. Instead of candy, we bought popcorn. We also bought drinks and nachos. During the film I laughed a lot. I liked the film very much! After the film we went to the zoo. The weather became good while we were in the movies. We saw many animals at the zoo. My favorite animal is the zebra. Because of the good weather, the zebras were outside. I waved at them. Then we went home. It was now very late. I hugged Sarah and I brought her to her house. Sarah and I had lots of fun. I will have another fun weekend with Sarah!

SORRY for my really bad German...:P

I'm really stuck on this question! Can anyone explain it me, if it's not too much to ask? Thanks!

To produce 40.0 grams of silver chromate, you will need at least 23.4 grams of potassium chromate in solution as a reactant. All you have on hand in the stock room is 5 L of a 6.0 M K2CrO4 solution. What volume of the solution is needed to give you the 23.4 g K2CrO4 needed for the reaction?

Thanks in advance :)

There's a song I like called "La Nueva Cordena" but I don't know Spanish, so I looked up the title in google translate and it wouldn't say what cordena was...does anyone know?

Just wondering how many people are in school and on Y!A :D

My teacher gave us this to answer, and I have NO idea what it means, I googled and wikipedia'd it, but it didn't tell me anything. Does anyone know? Is it even any of those?

This is kind of random, but I was wondering, if your parents speak two languages and you know them both fluently and use them both regularly, which one do you think in? Is one language used more often for thoughts? Why or why not? This is kind of random; thanks for any answers!

It just fell down the stairs and the screen cracked, but not too badly it's still usable...and we've had it since Christmas...can you exchange it for little or no money?

I'm a penguin and I would like to share this with as many people as possible =)

-human translators not Google or online!!!-
