Thanks

why?

Do waves with different frequency of the electromagnetic waves interfere?

PE=mgh , gravitational potential energy=mgh. The potential energy in the microscopic world is the energy used to break the bonds. and thus that is stored in the substance For instance, for a water to become vapour, you know that the volume is increased largely. With the same amount of molecules, you know that the distance between any two molecules may be lengthened in order to provide a larger volume. Take water molecules as example again In chemistry, molecules are bonded with intermolecular forces, (i.e. Van der Waals' Forces).To break the bonds, in other words, to seperate them, energy must be input. Energy is then converted into their potential energy rather than their kinetic energy. Hence, gas has a larger potential energy than liquid. I would think that the product is hydrogen peroxide at a particular temperature or with some kinds of catalase. However, I don't know how to predict it. I just know the reaction by memory. Hope someone can help me.

Just like zincate? May I know what the product is when the rust reacts with ethanedioic acid?

I heard of the drying of sponges in a cartridge. Probably mine is in this case. I tried to fill in two-third of a inkjet refill kit, but there is no ink leaking out even I smear the cartridge mouth with a moist paper tissue. In fact, I suspect my way to refill in it. I don't know the proper method and I just forced the ink into the cartridge, lol.

No non-toxic white gas? Every gas seems to be "toxic" if it reaches a certain concentration.

I cleaned. I guess the errors are caused by the normal decline of the cartridge. Do you know how long a cartridge can last for?

Titration is required.

Where is the setting?

Normally, neutralization should be more easily than a reduction.

I got a problem on my cartridge. I thought it was almost out of ink, so I refilled some into it. But after that, the intensity of the black colour decreases. I am absolutely sure about it. The most strange thing is: My printer is all-in-one. That means I can scan some documents and print them out without my computer on. The intensity of the black colour is normal and perfect for this option. Can anyone help me? In the photo, the background and the text show their difference in intensity obviously.

To melt a metal, lots of heat energy is required to overcome the strong metallic bonds. Hence, a high temperature needed to be achieved. Though mercury has a low melting point, it is very toxic. I don't think we can handle any liquid metals in that mean.

Thanks

Any form will do the job

Oh I misunderstood something. now ok

Why ethanedioic acid is present?According to my book, ethanioate ions have a higher reducing power than H+? so ethanioate ion will be oxidized and H+ will be reduced. One more question: Why Aqua regia does not last very long?

I want to extract the information from SFN and put them in my desktop.

A desktop search is provided by the google. Is the search only on the desktop or on my whole computer? I want to copy whole the information, replies, thread from the SFN into my desktop, is there any method?

Can you tell me what the main difference between uric acid and urea besides their acidity or alkalinity is?

Urea is hydrolyzed into carbonate and ammonium ions, what are the exactly name of the products?

It's different from uric acid so I have no idea.

acidic?>

Urea is an organic compound of carbon, nitrogen, oxygen and hydrogen, with the formula CON2H4 or (NH2)2CO. I heard that it is an odourless solid, is it true? What's its pH?

All the reactions are reversible. Even, there is only an atom, it still get a chance to lose electrons.
