Sorry, I am too lazy to have a look at this passage. I support what lgg say, 0^0=undefined=0/0, right?

Would you guys show the prove of after finding that number, n 3x+5y=n+k, x and y are non-negative integers vary with the change of k where n and k > 0.

Why not use higher temperature? Does the volume of it increase and provide a better ideal gases environment?

Sorry I have no idea on it Go to http://en.wikipedia.org/wiki/Dextrin for more details, I am sure it can help you !

Sorry, wrong spelling, should be quadratic

Do you still need the formula? If you do, I try to write it for you. But first of all, that would not be the perfect solution since I haven't learnt many algebra yet, such as quadric

All gases are 22.4 L for 1 atm , 273 K of 1 mol What would you choose the environment for counting the mol of gases?

Oh I see, that smells acidic. How does the hydrogen ion in sodium hydrogencarbonate come out? It seems to be very stable and inertly involve in the decomposition.

PV=RnT And Volume is inversely proportional to pressure. Volume and pressure are both proportional to temperature. What I am confused of is, when T is increased, Which volume or pressure is increased? How to make the pressure remains constant in order to test the relationship between volume and temperature? Also, Increase in pressure would increase the speed of molecules, and aren't them moving faster and make the volume increase?

Ya I think so too. Otherwise, the answer is over several hundred cents. And so... What's the question, can anyone tell me what it is asking?

Sorry, I don't understand what do "every price after that continues at an interval of 1 cent"mean?

Why do the carbon dioxide react with water to form hydrogen carbonate molecule again after that?

Try not to spam or scolding other will give you a longer play. [i edit because I think of something] How can we vary our ip? I've tried a software but it is not free.

I get trouble in a rope question. O - F - is a rope. O=object(a Box) Is the force for box to endure the right force is only the static frictional force? Also, is that true if the box moving in space, the rope does not be straight? How about if the reacting force only occur when the box is in stationary and with exact 0m/s2 acceleration?

Can quantum mechanic predict which chemical decomposes naturally? Why is hydrogen carbonate so unstable while sodium carbonate is so stable?

OK thanks

Regard to my little knowledge in chemistry area, I think of nothing. Ya sublimation of carbon dioxide provide a lot of gas smoke, it is commonly used in drama. It is also a cheap and can be approach easily.

I use http://en.wikipedia.org/ this encyclocpedia too!

How about in a molecule on the sun, would the pressure give to the lower part is more than the upper part very much? Also, how does a drop of salt water taste salty?DO Chloride ion and sodium ion combine again when leave the big water MATRIX?lol

2- 4+ 2-? Is it? I'm still confused. Maybe I need to find another deeply chemistry book than my current one. "...pull the central atom" So I think the "the distance of the shared electrons between the oxygen atom and a carbon atom is the same. So that's a non-polar covalent bond. "

I have just learnt simple photosynthesis, but I'd try my best. Plants do not want to combine the oxygen molecule with hydrogen atom because the hydrogen atom is needed to carry the light energy into the light independent stage ( combine with CO2) Oh Are you talking about water molecule combines with carbon dioxide to form glucose and do not give oxygen? I'd think it's because energy is needed during reaction and the energy for the combination of two molecules are large than just very "light" hydrogen atoms to combine with carbon dioxide atoms. OR the oxygen molecule may affect to form carbonhydrates. Am I right?

Do air pressures act towards the sky ?

I heard that wrapping a book or a coat which are labelled with some anti-stealing things with an aluminium foil could leave the entrance of the shop. How does it work?

1.Is that when bonding, the electrons are first coming to the oxygen atoms. 2.The oxygens are attracted by the positive charge carbon "ion"(seemed to be ion) 3.The carbon "ion" can't move to the oxygen "ions" because they are both pulling it. 4.Then dramatically, the distance of the shared electrons between the oxygen atom and a carbon atom is the same. So that's a non-polar covalent bond. Is that because force occur in speed of light, so the 4 STEPS occur in the same time? I really want to know whether this concept is wrong? Please kind to tell me!

If you mean the hydrogen atoms the product carries, then it is 12H2O----->24H +6O2 then hydrogen atom is used to combine with carbon dioxide 24H + 6CO2 ---> C6H12O6 + 6H2O the overall equation is 12H2O+24H + 6CO2----->C6H12O6 + 6H2O + 6O2 The six water molecule will be used again, so the hydrogen atoms are mainly in the glucose molecule. There is a limiting reactant, CO2 You can calculate the gram of CO2 first and then you may get the gram of glucose produced. Just find the ratio of the weight of 12 hydrogen atoms in a molecule of it to the weight of a glucose molecule. The last 6 water molecules in experiment is not used for the photosynthesis. However, I think they do not leave because they are used with oxygen to oxidizing food to generate energy. Hence, this theoretical product is not the same as the analyzing value. To obtain a preciser result, I suggest you to kill the plant immediately. Is these things you are finding?
