Solid copper is added to nitric acid, and copper(II) nitrate, nitrogen dioxide, and water are produced.

What's the balanced equation for this?

The skeleton equation would be like;;

Cu + HNO3 yields to CU(NO3)3 + NO2 +H2O

The numbers are subscript, of course.

In 2004 Bush re-instituted lunar exploration as the primarary goal of NASA, partially because of the advanced programs of China, the EU, and India. The resources on the moon are a potential energy source for the next millenia.The cost is estimated at 100 billion dollars. Heium3, which emits hardly any neutrons during the fusion process, rendering it almost harmless to the containment grids, is abundant on the moon, according to samples from the Apollo missions. These samples were given to other nations as a good will gesture during the 1970's.Is there a new space race for the moon now, and is it essential for the US to use our past expertise at getting to the moon to ensure we capture the untold benefits of this limitless energy source?

Apart from lifestyle factors such as diet, stress, toxins, is there something in our DNA that will determine how long each one of us lives?

In other words, is there a biological clock ticking in our DNA that determines the maximum age you can live?

I'm sorry the title is so gruesome, but I have a question, I have heard in urban legends, people talking about news and things like that, that when a person puts a dog, cat, or baby ((O_O something I would never do!)) in a microwave, the subject explodes after a while, our friends were discussing this when we heard a man killed a baby by putting it 40 seconds in the microwave, and a dog exploded after 4 min.
I have heard about these stories, but never seen it happen, when my tea cup goes in the microwave with some stranded little ant, even though I put it 1:50 seconds, nothing happens to the ant, when I put a chicken in the microwave, lets say im cooking a whole chicken for 10:00 min. or more, it doesn't explode, so why would a cat, dog, or any other animal that fits in it explode?

"You [the scholars of hadith] are the pharmacists but we [the jurists] are the physicians." This was explained by `Ali al-Qari in his book Mu`taqad Abi Hanifa al-Imam (p. 42): "The early scholars said: The hadith scholar without knowledge of fiqh is like a seller of drugs who is no physician: he has them but he does not know what to do with them; and the fiqh scholar without knowledge of hadith is like a physician without drugs: he knows what constitutes a remedy, but does not dispose of it."

I am writing a story that takes place in the future and i was wondering how to stop the moon from escaping the orbit of the Earth via mining material from the asteroid belt and bringing it to the moon. What are the mathamatical equations needed for such a feat?

example.-- how many cubic tons would it take to halt the moon from traveling any farther from the Earth and stabilizing in a fixed orbit and yet not having the gravitational pull to send it hurtling back at Earth and killing all life as we know it?

My 9 year old son is always asking questions. Sometimes I can answer, sometimes I can't. Here is one that he asked several weeks ago. He wanted to know where the air goes when someone is born. He said "there are so many people and animals born all the time, what happens to all that air that their body takes up? I wasn't sure how to answer. If anyone has any intelligent answer that would be great. Please no smart a@# comments. Thanks

I hate chem because it is hard to visualize and i am terrible at word problems. Also there is tons of things you need to know and memorize in order to have a good foundation for later topics.

Is there any book or anything that makes chem more fun to learn? any ideas?? or how do you approach learning chem?
