How many grams of methane [CH4(g)] must be combusted to heat 1.20 kg of water from 23.0°C to 85.0°C, assuming 1.00E2% efficiency in heat transfer?

And

At one time, a common means of forming small quantities of oxygen gas in the laboratory was to heat KClO3:
2KClO3(s)--->2KCl(s)+3O2(g) H=-89.4kJ

For this reaction, calculate for the formation of the following:

a) 0.805 mol of O2
b)10.85g KCl

And

after reading quite a bit about it...pro and con...it seems to me it's real and coming soon. Fuel shortages or high prices, fuel siphoning, food shortages due to high delivery costs, economic effects, etc. So my question is, where do you want to be when the **** hits the fan?

Hello,

I am playing pick up soccer once or twice the week. In the last 3-4 months I felt a kind of stiffness in my right knee. At the beginning I felt only that my movement was not as usual and during the game I did not feel anything. In the last 3-4 weeks I feel during the night pain in my right knee which goes away during they day. I am not limited in what I am doing and when I rest my knee for a longer time it feels fine. But I recognized after playing soccer that the pain always comes back during the night for one or two days. Then it disappears .... Any ideas?

Of course I plan this week to get it checked!

Thx, Roman

i did an experiment on the energy in sunlight. i measured the temperature of an aluminum block sitting in the sun for 30 minutes and kept track of what degree celsius the thermometer gave me each minute. i've written up my report (including making a graph), but it lacks a thesis and a conclusion...because i don't understand what the experiment is supposed to prove...i just wrote what i did for the experiment and what happened...i'm at a loss, seriously. i feel like there should be something more to the experiment than "it got hot," but what???

I was talking to my boyfriend about this and I expressed to him that I have no intentions of changing my last name. I have had to spell my first name my entire life, but my super easy last name makes up for it. If I were to take my boyfriend's last name, then I would be spelling both my first and last name for the rest of my LIFE. Besides that, I really just like my name and it just seems to fit me and be so much of a part of me that I could not imagine being called something else. He became kinda upset and feels it is only right for the woman to take the mans last name. He asked me to compromise by hyphenating. That is not an option either. He feels that my independent nature is the real reason behind me refusal to change my name, but it really is more about keeping my identity...the person I have been all my life. Am I wrong? Selfish?

I woke up at four in the morning because he punched me really hard in the middle of my back. He kept his fist out and in my back until I said, "Stop! You're hurting me!" I started crying because it hurt so bad! He feels awful about it and has been apologizing all day. Is there any way to help him sleep soundly without flailing around?

My son started out with one spot on his face that kept getting bigger and bigger and then he got another spot a month later.. now he has two or three more spots.. but they're only on his face. We got referred to a dermatologist and she swabbed it but it was mostly just blood that she got out, no pus or anything, but they checked for an infection and said there was none and that his skin would just grow over it. Well, its NOT going away and his skin is NOT growing over it, its getting WORSE! So we went back to the pediatrician and he gave us more bactracin cream but that was it. He said it should be gone by December or else we're going to have to talk surgery to remove all of them and my son will have scars all over his face. I do NOT want him to have surgery... what should I do??? Also, he took an antibiotic for about 3 months and it did absolutely nothing. Thank you for all of your help and please pray for my son, I think it hurts his little face!

I'm a 24-year-old college student, and over the summer my parents found out I smoke marijuana and gave me a couple urine tests. I decided to stop smoking completely for the entire summer (without any difficulty, I must add), so I passed both tests. Now I'm back at school and smoking a few times a week, but I'm concerned my parents may test me again when I come home for Thanksgiving. So I'm trying to figure out the best way to test negative, in case they test me again. I'm willing to stop smoking again until Thanksgiving if it comes down to that, but I want to see what other options I have. A local head shop sells a drink called Detoxify, which they say diverts the THC metabolites into your colon or something so that it won't show up in your urine for a few hours. That sounds good, but I'm not sure if it's 100% reliable, and I heard some tests can detect these drinks, although the people at that head shop say it won't show up because it doesn't mask the THC. Any advice?

Can you actually stop loving someone or do you just ignore the feelings you have, put the past behind you and move on with your life?

Assuming there was no abuse, no cheating, no fighting...things just didn't work out due to circumstances beyond your control.

I'm just asking because at what point, without a legitimate excuse, does it become acceptable to withhold sex? Obviously marriages are important, but at what point do you say enough is enough with the sex issues. I am asking not as much for myself, but friends of mine who have wives withhold sex on a regular basis and we were talking about his the other day, so just curious about people's thoughts on this subject.

For halloween I'm being the tooth fairy, so I made some tooth earrings out of play dough for the costume. I really like how they've come out, but I'm afraid that if they're still soft on halloween and they get caught on something or somebody touches them, they'll be completely ruined. What can I do to make the play dough dry and become solid?
