CHEM 1201 Lecture Notes - Lecture 3: Sulfuric Acid, Nonmetal, Oscilloscope
Document Summary
Chemical equations give a description of a chemical reaction. Reactants (written to the left of the arrow) Products (written to the right of the arrow): They give the relative number of molecules, atoms, ions, etc. involved. The nature of products formed during the reaction. The correct chemical rxn is determined by experiments using various analytical methods. 3 - - and sophisticated instrumentation to analyze the products. 2 h2 + o2 2 h2o sets of numbers in a chemical. Stoichiometric coefficients give a ratio relationship between the reactants and their. The subscripts give the ratio to which the. Coefficient: 2 h2o means that there are two. 4 - - water molecules present for every. Subscript: per h2o molecule there are two h atoms for each one molecule of water and one o atom for each one molecule of water. Note: in 2h2o there are 4 hydrogen atoms present (two for each water molecule).
