Information Given:

A 0.324 g of iron salt was put through a cation exchange column and then titrated using 0.198 M NaOH as the titrant.

It took 8.38 mL to reach the first equilvalence point and 17.77 mL to reach the second equilvalence point (volumes read directly off graph).

What is the percent by mass of potassium and iron in the sample?

1. What is the volume of titrant needed to titrate all of the potassium?

2. What is the mass of potassium found?

3. What is the percentage of potassium salt?

4. Volume of titrant needed to titrate all of the iron?

5. Mass of iron found?

6. Percentage of iron in salt?

If someone can just explain how to do the first part for me (1-3) I could probably figure out questions 4-6. Please please please help, I have no idea where to start!

Thanks!

Okay, so over the past few months I have been experiencing hair loss. I used to have very thick and healthy hair and now it's dry, thin, and only getting thinner. At first I thought it was the stress of leaving for college and dealing with classes that was making my hair fall out, however, I have been home for a month and it has been falling out more than ever! Its come to the point that if I run a brush through my hair once or twice I will have around 40 hairs on it from that alone. My scalp has been somewhat itchy in some areas...could this be because of my hair falling out? Also, I find that I have been pretty tired recently, I will sleep in until noon and be tired again by 8 or 9. Also, I have been working out a little more than I did back at school..could this be a reason? I am just not sure anymore. I had been taking prenatal vitamins but have decided to stop taking them until I figure out what the problem is. Instead I have been taking biotin and Iron supplements, and was considering using extra virgin olive oil or coconut oil on my scalp and ends. I have also ordered Mira Hair Oil to give that a try. I am making a doctors appointment tomorrow, therefore I am not asking for a diagnosis just suggestions. Anything will help!

I am 19, pretty healthy and active, and not pregnant. I drink a lot of coffee, and when I first got to college by alcohol intake increased quite a bit...but as of summer I have completely stopped. (Just some small facts).

Thank You!

Even though I've had my period for about 4 years now, my cycles are never dead on...I am either a few days early or up to a week late. I never really track my periods but I have a pretty good idea on what days they usually fall. Around may 11th I was fooling around with a guy. I was on my period during this time so I had a tampon in. He may have touched himself (after he came) and touched me. However no penetration occurred (obviously). Not even his fingers were inside. So Last month I was extremely stressed out and wasn't exercising as much because of finals..wasn't really sleeping either or eating all that much and my period was about 4 days early. Now I've been home for a month or so...I have been eating healthier (more vegetables and eating three meals), I have been working out about 6-7 days a week for about 1 1/2 each day, I've been sleeping at least 8 hours. But my period still hasn't come.....could this sudden change be the reason why it is so late? My chest has been somewhat swollen and sensitive (not too bad) for about 5 days now. I have slight cramping in my lower abdomen and my face broke out about a week ago...plus i have been craving sweets quite a bit...could this be an indication that it is finally coming or should I worry?

I take these once a day.

500 mcg B-12

1000 mg Fish Oil

500 mg Cranberry

1 Prenatal (Spring Valley Brand)

500 mg Biotin

Okay so I am 19 years old, about 5'8 1/2 , and 145 pounds.

I really want to lose around 10-15 pounds. What is a good meal plan to do so? Also, I have been going to the gym at least once a day for two hours, sometimes even twice a day. However, my urge to eat has sky rocketed lately....is there any way to curb these intense cravings?

Thanks :)

*Sorry It's a bit long*

Okay....so I have known this guy since the beginning of the year. We had met at a party (classy I know) , and had been talking on and off since then. Well about 5 months ago he had sort of played me and this other girl that he was seeing. One night, he told me that him and this girl were over. Well things led to other things and we ended up having sex. The next day I found out from one of the other girls friend that she was completely distraught because they were apparently still together when I had sex with him, yet he told me that they weren't. I know he had played me for awhile, but I wasn't sure what to believe. According to him and a couple of guys he lived with, she would how up at his door all the time unexpected even after he told her he didn't want to be with her. Well now, a couple months later, she is completely out of the picture and had been for quite some time. Him and I had started talking again at a party and once again we ended up having sex a few times since then. At one point we even decided to declare a "friends with benefits" relationship. This went okay for awhile until he told me that he liked me (and straight up admitted to liking everything about me). This kind of told me to back off a bit because I didn't trust him at all. And I would stop talking to him for days at a time and he would continuously text me. Last time we hung out, I had went over strictly for sex but instead of going straight to the bedroom he wanted to hang out for a little bit, so we did. He always insists that we cuddle after the deed and kisses me on the head all the time and up my arms, its quite funny actually. For awhile I had thought that he liked me...however, some of his texts insist that he only wants me for sex. He always said he wouldn't allow me to "move on" whenever I told him I was done with him. I'm not heartless, I just don't want to get hurt by him again. Does this sound like he is just complimenting me or doing these things to keep me wanting to come back and sleep with him? Are these feeling that he tells me he has for me a fake way of keeping me interested? What should I do about the situation?

:)

Ever since I lost my virginity earlier this year, I had had sex quite a few times with the same guy. Now it has been around four weeks, maybe even longer since I am now home from college and we live far apart....but is it normal to think about sex all of the time and get turned on very easily?

A gas mixture contains 1.15 g N2 and 0.94 g O2 in a 1.46 L container at 19 degrees celsius. I already calculated the mole fraction of N2 ( = 0.58) and the mole fraction of O2 ( = 0.42).

So my question is :

How do you calculate the partial pressure of N2 and O2 using the information above?

Okay so during sex I often find it difficult to orgasm without some sort of clit stimulation, I am sure there are other women out there who know what I am talking about. My newest partner doesn't really ever touch it the way I would like him to, even when I told him what I wanted...he must have thought it was strange because he only did it for about two minutes which wasn't nearly enough. How can I convince him that that is the only way to get me to climax the way he expects me to?

Also, I know a lot of men like it when women pay attention to their testicles during oral......is it weird that I am kind of too shy to do so during oral? Is this weird and how can I fix this?

Sorry if some of the explanations seem provocative, I am just not sure how to explain without doing so. Thanks!

What are the net ionic equations of the following reactions?

1) Cd(NO3)2 + NH4OH

2) Fe(NO3)3 + NH4OH

3) Al(NO3)3 + NH4OH

--------

4) NaI + AgNO3

And what is the net ionic equation formed with KCl?

Thank You!

Okay so I am supposed to start my period around the 20th of this month.....however, this past friday I had unprotected sex and although I realize how stupid that was now, I am really beating myself up about it now. I have been worried because about 4 days ago my breasts became a little tender. I usually get sore breasts before my period is about to start so I didn't think much about it. I haven't experienced nausea, discoloration of nipples, or back pain of any sort....however the fact that my chest has been a little sore worries me. They aren't painful or overly sensitive...I can still run at the gym or touch them without feeling a lot of pain. My question is, should I be worried about possibly being pregnant or does it seem to be premenstrual symptoms? Also, I have recently changed my exercise habits so I have been going to the gym more frequently...do you think that could possibly be causing this? Or may even prolong my period coming?

Any advice would be helpful, please no lectures :)

Okay, so this past friday me and my boyfriend had unprotected sex and he pulled out. I definitely know now that that was NOT a good idea....My period is due in about a week and I have been working out at the gym everyday...not to mention stressing a bit. My boobs are somewhat sensitive and sore, I feel bloated, tired, and somewhat moody...could this just be my period coming soon? Or.....

Please no lectures, i know it was a bad idea and believe me after the stress it has put me through so far...it will NEVER happen again.

So, I've recently became sexually active, and although I was aware of the "pee after sex" to avoid UTI rule, I neglected to do so one night, and sure enough.....i got one. So my question is, and it may be a stupid question, but I couldn't really find the answer i was looking for on google. But, can you get a UTI if you don't pee after masturbating? I never used to masturbate before I had sex..weird I know...but im always worried not that ill get another uti.....it was terrible aha.

Okay so Im trying to come up with a user name for my new account......the only thing is...it seems as though all of the user names i made in the past, i end up not liking them later on.

I wanted to make one that incorporates my first and middle name... Emily Megan...

Think of this is a game(: aha ready GO!

I know it wouldnt be worth much more than the starting price but here are the details:

-1997 Matchbox

-Part of the retro 70s collection

-Limited edition ( 1 of 25,000 made)

-World class series (13)

-unopened package in mint condition.

Im pretty healthy, I workout on a daily basis, and for the most part eat really healthy. Ive recently decided to take vitamins, and I was wondering if what Im taking is too much or is okay to mix.

I currently have:

1,000 Mg Vitamin C

500 Mcg B12

1,000 Mg Fish Oil.

Are these vitamins okay to mix?

also on the fish oil bottle, it says adults should take 3 capsules a day, im assuming that would be too much since im just starting to take it and since im mixing it with other vitamins?

I am aware that for accurate advice i should consult my physician, but I just want opinions for now?

Thanks(:

I have to write a paper for my economics class. This paper focuses on negative and positive externalities. We were asked to find an article that discusses one or the other, or both.

So i was wondering if anyone new of a product...etc, that would be considered a negative AND positive externality. also, if there was an article link that went along with your idea that would be nice.

Any help would be much appreciated!! plus you get 10 points:)

Thank youu.
