Which is the best sound recorder ?
There are many best sound recorders that offer great futures and cost less. Some of them are Philips LHF0655, Sony ICD, Olymous VS, Zoom H4n and many more.
How do you record from an external microphone it's a H4N Recorder and your laptop at the same time?
You can't. The H4n is a USB audio device, and you can only use one input device at a time with recording software such as Cubase, which is bundled with the H4N. It is possible to record 2 inputs, from the H4N's 1/4" or XLR inputs at once.
I have an external microphone and I want a cheap good quality audio recorder that I can plug my mic into and record for my film I am also wanting it to be easy to access through a laptop suggestions?
The Zoom H4N records MP3 or WAV files directly to SD cards, These can be plugged directly into most modern laptops.
Why is ammonia written as NH4 and not H4N?
The first thing is that your question is flawed. Ammonia is NH3, not NH4. NH4 is ammonium, which takes on an extra Hydrogen atom. That said, the Ammonium atom can certainly be written as H4N as well as the ore common NH4.
In household ammonia are there the compounds of ammonia nitrate or ammonia sulfate?
Ammonia nitrate and ammonia sulfate are not proper IUPAC or common chemical names. Household ammonia consists of ammonia gas (NH3) dissolved in water. Once dissolved in water, part of the ammonia reacts with water to produce equilibrium concentrations of the positive ammonium ion, H4N+ and the negative hydroxide ion, OH-. The relevant equilibrium chemical reactions are: (Reaction#1, ammonia dissolution) NH3 (gas ) + bulk H2O = NH3 (aq) (Reaction#2, reaction with water) NH3(aq) + H2O = H4N+ + OH- (Reaction#3, water dissociation) H2O = H+ + OH- As usual, the equilibrium conditions for all three reactions must be met simultaneously.
How does aqueous ammonia or hydrazine hydrate increase pH?
Bases, with partial negative charges and overshielded nuclei, grab protòns from watter. In azo molecules, lone elèctronic pairs on the nitrogen are these negative ends. ammonia: H3N + H2O → H4N+ + HO− hydrazine hydrate: H2NNH2·nH2O + H2O → H2NHNH2+ + n H2O + HO−

Why iron corroded in the presence of ammonium carbamate?
Ammonium carbamate is a chemical salt resulting from the reaction of ammonia and carbon dioxide. The structure is: H2N-C(=O)-O(-)(+)NH4. Ammonium carbamate can be formed without any intermediates by passing ammonia gas over solid carbon dioxide (dry ice). In the real world, there is often water present and this complicates matters. Carbon dioxide and water can react to form carbonic acid, H2CO3. Carbonic acid is a diprotic acid and can react with 2 equivalents of base, so, when carbonic acid reacts with ammonia, ammonium bicarbonate begins to form; HO-C(=O)-O(-)(+)NH4. As more ammonia is added, ammomium carbonate begins to form; H4N(+)(-)O-C(=O)-O(-)(+)NH4. These are equilibrium reactions. As the concentration of ammonium carbonate increases, there is a conversion of some of the ammonium carbonate to ammonium carbamate. This is a dehydration reaction. An industrially important chemical that is derived from ammonia and carbon dioxide is urea, which is used as fertilizer. Urea is ammonium carbonate that has given up two molecules of water; H2N-C(=O)-NH2. The fertilizer plants that manufacture urea have severe corrosion problems due to the ammonium carbamate intermediate. The corrosion is so severe that carbon steel cannot be used. Some parts of the process will corrode 316 stainless steel. Those heated sections are manufactured from special alloys. Why does iron corrode in the presence of ammonium carbamate? Ammomium carbamate is hygroscopic and will attract moisture. Wetted ammonium carbamate will become an equilibrium mixture of ammonium carbamate and ammonium carbonate. This combination of salts and moisture attacks the protective oxide layer on the surface of steel with chelation-type mechanism. This exposes the underlying base metal for further attack.
