what is the correct name for (NH4)2CO3?

(NH4)2CO3 is Ammonium Carbonate

Reaction One (CO is Co I'm assuming ... they are NOT equivalent) is a double replacement. The products will be aqeuous KNO3 and insoluble Co(OH)2\n\nReaction 2 is a redox. The product will probably be Mg2N3 (Magnesium Nitride) but I'm not entirely sure if that chemical formula is correct. The magnesium is oxidized and the nitrogen is reduced.\n\nAg + H2SO4 ---> Maybe Ag2SO4 as a redox.\n\nF2 + KBr ---> KF + BR2 Single Replacement

The stock name for this compound is ammonium phosphate.  \nThis is an ionic compound, which means that it is named with the names of the ions.  The cation (the first ion, positively charged) is NH4+, which is called ammonium.  The anion (the second ion, negatively charged) is called phosphate, PO4(3-).  \nNote that because the entire compound must be neutral, there are three ammonium (+) ions to balance out one 3- PO4 ion.

N2+3H2=2NH3\n\nFirstly elemental symbols start with capital letters\n\nSecondly you need to know what they mean\nN2 = molecule of nitrogen\nH2 = molecule of hydrogen\n\nThirdly you need to know that NH3 is called ammonia\n\nThen it says 1 molecule of nitorgen + 3 molecules of hydrogen combine to form 2 molecules of ammonia (NH3)

Here is the right equation for nitric acid and sodium bicarbonate\n\n\nHNO3 + NaHCO3 ---> NaNO3 + H2O + CO2\n\nIf you do not like the sodium:\n\nHNO3 + HCO3(-) --> NO3(-) + H2O + CO2

tetraquadithiocyano cobaltate(III)\n\nThat's tetraqua dithiocyano, which looks confusing because it has a "quad" in it if there's no space. It comes from the four waters (tetraqua) and the two thiocyanates (dithiocyano). Put the anion after the name with a space.\n\nBy the way, the only reason there's a space between cyanocobaltate is because Yahoo Answers cuts off a long word and replaces it with "...". Not sure why.

This compound is an amine.  You can identify it by the NH2 (amine group) at the end.  You did a fair job with the structure considering the limits of the text here.  I am sure you realize that two of your carbons do not have the correct number of bonds.

The answer is very basic. Start with chemical names.  Carbon dioxide is made from carbon and oxygen. Carbon is called C, and Oxygen is called O. If you have two atoms of O, and one atom of C, then you have Carbon dioxide. The shorthand notaion for this is CO2. Don't be afraid of chemical formulas, but bring yourself to be comfortable with them, so you don't freak when you have to do a problem like this:\n__H4C + __O4Fe---->__HCO + __Fe. (this is balancing equations, but they're easy, once you learn to decode what chemical equations are trying to tell you )\n\nOn this website, just look at the ones that are relevant:\nhttp://www.ukrocketry.co.uk/forum/index.php?s=e26325e497d951d76619a79a0ad64ae7&showtopic=381\n\n\n\n\n\nThis si a segment on this from my school textbook: (sorry, its kinda long)\nA molecule or compound consists of at least two atoms that are chemically bonded. The chemical formula of a molecule or compound states how many atoms of each element are in one of its molecules. This formula is similar to an algebraic formula in its use of symbols. The description of a compound with numbers and symbols is called a chemical formula. Some formulae can be quite complex.\n\nQuestions you may have are:\n\nWhat are chemical compounds? \nWhat is the numbering system in a chemical formula? \nHow do you designate complex compounds? \nThis lesson will explain the basics of chemical formulas. \n\nChemical compounds\nA molecule is the chemical combination of two or more atoms. They can be of the same element, such as in the oxygen molecule (O2) or different as in the water molecule (H2O)\n\nA compound is a molecule that is made up of at least two different elements. The water molecule is a compound. When atoms of different elements combine to form a compound, the result is a new substance that has different properties than the original elements. A good example is when the poisonous green chlorine gas is combined with the explosive metal sodium to form the white salt crystals we use in our food.\n\nThe study of Chemistry is mainly interested in the formation of chemical compounds, since there are so many possible combinations of elements.\n\nChemical formulas\nChemical formulas (or more correctly: formulae) are designations of molecules and compounds in shorthand notation, similar to that used in Algebra.\n\nElements can be written as abbreviations or in a shorthand notation. For example, He denotes helium, Fe denotes iron, and Cl denotes chlorine. A chemical formula is writing the elements of a compound, using their abbreviations.\n\nThe combination of two or more elements to form a molecule is designated by writing their abbreviations next to each other. For example carbon monoxide is written as CO. The order in which the elements are written is typically alphabetical, but there are a number of exceptions for historical reasons and to clarify the geometry of the molecule.\n\nIf there is more than one atom of a type in the molecule, the formula shows it by a small number after the symbol. For example, water is H2O, which means there are 2 atoms of hydrogen and one atom of oxygen in the molecule. Carbon dioxide is CO2, which means there is one atom of carbon and two atoms of oxygen in the molecule.\n\nTo show the number of molecules, a full sized number is located in front of the molecule. For example 4 molecules of carbon dioxide is designated as:\n\n4CO2\n\nThis means there are a total of 4 C atoms and 8 O atoms in the combination. A way to remember this—taken from Algebra—is to think of it as 4 x (CO2).\n\nComplex formulae\nJust as in Algebra, you can use parentheses to separate parts in a complex formula. One example is the formula for nitroglycerin, a highly explosive substance.\n\nC3H5(NO3)3\n\nThis formula shows that nitroglycerin consists of 3 atoms of C, 5 atoms of H and then 3 molecules of NO3. If the parentheses were not used, you might have a formula like:\n\nC3H5N3O9\n\nThe number of atoms for each el
