820243
the chemical formula of a hydrate would be:\n\nthe original anhydrous form x nH2O where n is any whole numbers\n\nfor example: CaCl2 (calcium chloride) may form several different hydrates--\nCaCl2 x H2O\nCaCl2 x 2H2O\nCaCl2 x 6H2O

A simpler formula will be SO2+NO2+CO2+H20 (unlimited)-> H2SO4 (strong and oxidant) +  HNO3 (nitric acid, stronger and oxidant) +  H2C03 (carbonic acid, weak but ´till corrosive, just like the soft drinks)

The formula for water is H2O i.e. there are 2 atoms of hydrogen and one atom of oxygen. Its molecular weight is 18 g/mol .

I agree that answerer # 2 is confused.  An "anhydride" is simply a compound that has a formula that can be derived from the formula of another compound by removal of molecules of water.  In other words, an anhydride looks like the dehydration product of another compound.  \n\nAn "acid anhydride" is a compound that looks like the dehydration product of an acid, and a "basic anhydride" looks like the dehydration product of a base.\n\ne.g., CaO is the basic anhydride of Ca(OH)2  (Ca(OH)2 = CaO + H2O)\n\nCO2 is the acid anhydride of carbonic acid (H2CO3 = CO2 + H2O)

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
