Chemical FormulasChemical Formulas - Chemistry and CompoundsChemistry is the science of chemical elements andcompounds and how these things work together - for moreinformation see the Beginners Guide to Periodic Chemistry.A chemical element contains only one type of atom. If asubstance contains more than one type of atom, it is acompound. A compound is a pure chemical substanceconsisting of 2 or more different elements that can beseparated into simpler substances by Chemical Reactions.Chemical Formulas - Chemical SubstancesChemical substances exist as solids, liquids or gasses( States of Matter). Most elements are solids, only 11 aregases and 2 are liquids. Substances may change betweenthese phases of matter with changes in temperature orpressure. A common example of a chemical substance ispure water.Chemical Formulas - Chemical ReactionsChemical reactions convert one chemical substance intoanother. A common example of a chemical substance ispure water. Changes in temperature can change from aliquid (water) to a solid (ice) to a gas (water vapour /steam).Chemical FormulasChemical Formulas - What is a Chemical Formula?What is a Chemical Formula? A formula in chemistry is atype of shorthand for representing the elements in acompound. Element Symbols are included on the PeriodicTable. Symbols from the periodic table are used for theindividual elements. e.g. O for oxygen, H for hydrogen, Cfor carbon, N for nitrogen, Ca for calcium and Na forSodium. Substances that have two or more atoms bondedtogether, and therefore more than one element, are calledcompounds. See Examples of Compounds.Examples of Chemical FormulasExamples of chemical formulas and their meanings areexplained in Examples of Chemical Formula and Equations.This page provides examples detailing how to write aformula or equation together with examples and the use ofsubscripts.Chemical Formulas - SubscriptsChemical formulas shows the symbols of the elements inthe compound and the ratio of the elements to one another.If a substance contains more than one atom of a particularelement, this quantity is indicated in chemical formulasusing a subscript number after the chemical symbol.Chemical Formulas - Examples of the use of SubscriptsThe subscript refers only to the element it immediatelyfollows. For example in formulas and equations, thechemical formula for water is H2O which indicates that 2atoms of Hydrogen combines with 1 atom of oxygen. Thechemical formula for sodium chloride is NaCl indicating thatone atom of sodium combines with one atom of chlorine ina one-to-one ratio. Subscripts are added, following theelement symbol, to indicate that the number of atoms ofthat element in the compound if it is greater than one. Forexample, the equation for magnesium bromide MgBr2 whichindicates that one magnesium atom combines with twobromine atoms.Common Chemical Formulas ListThe following list shows some of the most commonformulas for both elements and compounds.List of Common FormulasWhat is the Chemical Formula for SodiumNaSodiumWhat is the Chemical Formula for WaterH2OWaterWhat is the Chemical Formula for GlucoseC6H12O6GlucoseWhat is the Chemical Formula for AlcoholC2H6OAlcoholWhat is the Chemical Formula for Sulfate GroupCaSO 4Sulfate GroupWhat is the Chemical Formula for Hydrogen SulfideH2SHydrogen SulfideWhat is the Chemical Formula for SaltNaClSaltWhat is the Chemical Formula for Oxygen moleculeO2OxygenWhat is the Chemical Formula for EthanolC2H6OEthanolWhat is the Chemical Formula for VinegarC2H4O2VinegarWhat is the Chemical Formula for AmmoniaNH3AmmoniaWhat is the Chemical Formula for MagnesiumMgMagnesiumWhat is the Chemical Formula for Acetic AcidC2H4O2Acetic AcidWhat is the Chemical Formula for ButaneC4H10ButaneWhat is the Chemical Formula for AcetateCH3CO2 AcetateWhat is the Chemical Formula for NitrateNO3 NitrateWhat is the Chemical Formula for CopperCuCopperWhat is the Chemical Formula for Nitrogen moleculeN2NitrogenWhat is the Chemical Formula for Carbon DioxideCO2Carbon DioxideWhat is the Chemical for Sulfuric AcidH2SO4Sulfuric AcidWhat is the Chemical Formula for MethaneCH4MethaneWhat is the Chemical Formula for SucroseC12H22O11SucroseWhat is the Chemical Formula for PropaneC3H8PropaneWhat is the Chemical Formula for Baking SodaNaHCO3Baking SodaWhat is the Chemical Formula for FluorideFFluorideWhat is the Formula for Fluorine MoleculeF2FluorideWhat is the Formula for Hydrogen PeroxideH2O2PeroxideChemical Formula for CaffeineC8H10N4O2CaffeineWhat is the Formula for Sodium Chloride (Salt)NaClSodium ChlorideWhat is the Chemical Formula for AspirinC9H8O4AspirinWhat is the Formula for Hydrochloric AcidHClHydrochloric AcidWhat is the Chemical Formula for Zinc NitrateZn(NO3)2ZincWhat is the Chemical Formula for Carbon MonoxideCOCarbon MonoxideWhat is the Formula for Sodium HydroxideNaOHSodium HydroxideWhat is the Formula for Cyanide (Sodium Cyanide)NaCNSodium CyanideWhat is the for Cyanide (Calcium Cyanide)Ca(CN)2Calcium CyanideWhat is the Formula for GoldAuGoldWhat is the Chemical Formula for IodineIIodineWhat is the Chemical Formula for TinSnTinWhat is the Chemical Formula for BenzeneC6H6BenzeneWhat is the Formula for Hydrogen SulfideH2SHydrogen SulfideChemical Formula for AcetoneCH3COCH3AcetoneChemical Formula for Phosphoric AcidH3PO4Phosphoric AcidWhat is the Chemical Formula for PentaneC5H12PentaneWhat is the Chemical Formula for MethanolCH3OHMethanolWhat is the Chemical Formula for Hydrobromic AcidHBrHydrobromic AcidChemical Formula for Carbonic AcidH2CO3Carbonic AcidWhat is the Chemical Formula for TitaniumTiTitaniumWhat is the Chemical Formula for SodiumHypochloriteNaClOSodium HypochloriteWhat is the Chemical Formula for EthaneC2H6EthaneWhat is the Chemical Formula for AmmoniumSulfate(NH4)2SO4Ammonium SulfateWhat is the Chemical Formula for OctaneC8H18OctaneWhat is the Chemical Formula for Copper SulfateCuSO4Copper SulfateWhat is the Chemical Formula for CholesterolC27H46OCholesterolWhat is the Formula for Benzoic AcidC7H6O2Benzoic AcidWhat is the Formula for Sulfurous AcidH2SO3Sulfurous AcidWhat is the Formula for GalactoseC6H12O6GalactoseWhat is the Formula for Ascorbic AcidC6H8O6Ascorbic AcidWhat is the Formula for Dry IceCO2Dry IceWhat is the Formula for Sodium NitrateNaNO3Sodium NitrateWhat is the Formula for Calcium Oxide (Quicklime)CaOCalcium OxideWhat is the Formula for Iodic AcidHIO3Iodic AcidWhat is the Formula for Lactic AcidC3H6O3Lactic AcidWhat is the Formula for Magnesium BromideMgBr2Lactic AcidWhat is the Formula for Water VaporH2OWater VaporWhat is the Formula for OxideNo FormulaOxideWhat is the Formula for CarbonCCarbonWhat is the Formula for HydrogenHHydrogenWhat is the Formula for SugarC nH 2n O nSugarWhat is the Formula for SulfateO4S2-SulfateWhat is the Formula for Nitrous OxideN2ONitrogenFormula for Citric AcidC6H8O7Citric AcidFormula for OctaneC8H18OctaneFormula for CamphorC10H16OCamphorFormula for Silver OxideAgISilver OxideFormula for Arsenic TrioxideAs4O3Arsenic TrioxideFormula for Gold TrioxideAu2O3Gold TrioxideFormula for Gold SulfideAu2SGold SulfideFormula for BromineBr2BromineFormula for Aluminium foilAl2O3Aluminium foilWhat is the Chemical Formula for Acid RainSO2 (Sulphur dioxide) + NO2 (Nitrogen dioxide) +H2O (Water) = Acid rainAcid RainList of Common FormulasChemical FormulasThe above list provides details the most common formulasand equations.
