PPT-Calculation of Empirical Formulas

Empirical Formula consists of the symbols for the elements combined in a compound with subscripts showing the smallest whole number ratio Molar mass the mass in grams of 1 mole of a substance.

Warm Up: . 3. Minutes. A certain bag of M&M’s has 8 blue candies, 7 red candies, 4 green candies, and 6 yellow candies. What percentage of the bag is blue M&M’s? . Record your Learning . How can conjectural variation models help?. Alan Crawford and . Benoît. Durand. OFT Seminar. The questions. Can we use conjectural variation models to . measure empirically market power?. identify the source of market power? Can we use conjectural variation models to tell whether market power is the result of product differentiation or collusion? . You should know this for the quiz!. Empirical and Molecular Formulae. Empirical Formula. If needed, change % to g.. Do . a molar conversion to change from . g. mol. Divide each of these numbers by the smallest number. Do Now: from last years regents. Chemical Formulas. Tell . type. & . number. atoms in compound. Microscopic level: . Formula gives atom ratios. Macroscopic level: . Formula gives mole ratios. EXAMPLE. Get started. Imagine that Excel is open and you’re looking at the “Entertainment” section of a household expense budget..

Empirical thinking depends on past habit.. Based on observation and experience.. Ex. A-“It will probably rain tomorrow”. Seating Chart. Warm Up 1/5-6. Imagine your boss wants you to count the number of Styrofoam packing peanuts in a large bag. Suppose you found the mass of 100 peanuts to be 5.5 g. How could you use this to find the number of peanuts in the bag?. Recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts.. Recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass.. Microsoft Office 2010 Fundamentals. 1. Introduction. 2. The real power of a spreadsheet program such as Excel is its ability to perform simple and complex calculations on worksheet data.. Using the commands located on the Formulas tab of the Ribbon, you can enter formulas to perform calculations or use predefined formulas, called functions.. Chapter 5: Molecules and Compounds. Learning Goals. Write . chemical formulas.. Determine . the total number of each type of atom in a chemical formula.. Classify . elements as atomic or molecular.. Classify . Naming Ionic Compounds. The names of ionic compounds consists of the names of the ions that make up the compound.. Names of . cations. include the elements of which they are composed.. Names of anions are altered names of elements.. Lowest whole # ratio . H. 2. O. 2. (hydrogen peroxide) is it a empirical Formula?. No, you can reduce it to HO . . H. 2. O. 2 . is the molecular formula. Molecular formula shows the way the molecule is actually found in nature..
