The best bet is to go to a chemistry website and see if there is an explanation of chemical formulas. Also, you should be able to download the periodic table, showing all the elements.

HCl + NH4OH → H2O + NH4Cl.\nThere would be heat given off, so you could verify that a reaction took place.\n\n2HCl + Ca(OH)2 → 2H2O + CaCl2\n\nedit: The steps for balanacing the reaction:\n1)We know the salt produced is CaCl2, so an acid with Cl is HCl and a base with Ca is Ca(OH)2. \n2) write the skeleton reaction:\nHCl + Ca(OH)2 → H2O + CaCl2\n3) there are 2 Cl's on the right side, but only 1 on the left. To balance this, place a 2 in front of HCl\n2HCl + Ca(OH)2 → H2O + CaCl2\n4) Now there are 4 H on the left and only 2 on the right, so, place a 2 in front of H2O.\n2HCl + Ca(OH)2 → 2H2O + CaCl2\n5) check with the other elements, each side has one Ca, and 2 O. It all works out ☺

As mentioned above, Mg(HCO3)2\n\nIt was so easy.. in which grade u study?\n Do u know how to make formulae? Just learn the valencies and symbols of most commonly used elements... Here are some for your help...\n\nMagnesium (Mg): 2\nAluminium (Al): 3\nCarbonate (CO3): 2\nBicarbonate (HCO3): 1\nSulphate (SO4): 2\nBisulphate (HSO4): 1\nSodium (Na): 1\nBoron (B): 3\nBeryllium (Be): 2\nCalcium (Ca): 2\nPotassium (K): 1\nChlorine (Cl): 1\nBromine (Br): 2\nFluorine (F): 1\nNitrogen (N): 1\nCarbon (C): 4\nHydrogen (H): 1\nOxygen (O): 2\nHydroxyl (OH):1\nNitrate (NO3): 1\n\nI think they are enough for you...\n\nNow see how to make a formula:\nStep No. 1: Write the symbol of each element in a compound. \nE.g. You want to make the formula of magnesium bicarbonate. Write their symbols...\n\nMg HCO3\n\nStep No.2: Write their valencies.. \nThe valency of Mg is 2\nThe valency of HCO3 is 1\n\nMg (2) HCO3 (1)\n\nStep No.3: Now cross the valencies of each element.. It means write the valency of Mg with HCO3 and write the valency of HCO3 with Mg\n\nand here you go with the formula...\nMg (1) HCO3 (2)\n\nNo need to write 1 with any element..\nso it becomes,\nMg(HCO3)2\n\nHere are some more examples..\nPotassium hydroxide\nK OH\nK (1) OH (1)\nKOH\n\nCalcium hydroxide\nCa OH\nCa (2) OH (1)\nCa(OH)2\n\nMagnesium chloride\nMg Cl\nMg (2) Cl (1)\nMgCl2\n\nSodium sulphate\nNa SO4\nNa(1) SO4(2)\nNa2SO4\n\nAluminium nitrate\nAl NO3\nAl (3) NO3 (1)\nAl(NO3)3\n\nHere is one last rule for you:\nIf the valencies are equal, do not cross..\n\nExample:\nCalcium sulphate:\nCa SO4\nCa (2) SO4 (2)\nNow both the valencies are equal, so just cancel the valencies...\nand the formula becomes,\nCaSO4\n\nAhhhh... got tired... Hope this helps.. good luck for you submission.. Now u can also explain your teacher that how u got the formula...\ncya\nAllah Hafiz

Methylamine\n\nNext time, just type the chemical formula into http://en.wikipedia.org/ and see if they have your compound documented.

If you have the letter names, use the Periodic Table of Elements.  If not, use PH paper, and that might help.  Go by color, soluability, and texture.

The only other way I know of is to know the formula of a compound or ion/radical containing that element, and use the following rules:\n1. Total for all elements in a compound must be 0. Total for an ion is the charge on the ion.\n2. First element in a compound is always (+); last element in a compound is always (-). (Not necessarily true for ions: Hydroxide ion OH- has O -2 and H +1; I believe it's true for all other ions/radicals but not certain.)\n3. H is always +1 or -1.\n4. O is almost always -2, unless it's -1 or +2 because of one or more of the above rules. (Example 1: Oxygen molecule O2 has one +2 and one -2; Example 2: Hydrogen peroxide H2O2 has two H +1 and two O -1.)\nIn fact, oxidation number doesn't mean much unless it's in the context of a compound. As above, oxygen atom can be either -2, -1 or +2 depending on the compound it's in. In fact, a molecule with two or more oxygen atoms can even have its oxygen atoms in different oxidation states!

Step 1: Draw the Lewis structure.\nStep 2: count the number of double bonds.\nStep 3: count the number of triple bonds.\nStep 4: total up number of pi bonds from steps 2 and 3.\n\nThere is 1 pi bond for every double bond and 2 pi bonds for every triple bond.
