Unformatted text preview: Will any starting material remain? If you were in the business of making automobiles and you had 28 tires, 6 bodies and frames, and 5 engines, how many automobiles could you produce (assume no spare tire)? What limits your production? What is the limiting reagent in the following reaction to produce H 2 if we start with 750. g CH 4 and 400. g H 2 O? CH 4 + H 2 O CO + H 2 Mass Percent Composition From a chemical analysis on an unknown sample, we can 1) calculate % composition and compare to that for a known sample 2) determine an empirical formula What is the mass percent composition of butadiene, C 4 H 6 ? What if we have a compound that analyzes as follows: 35.0% N 5.0% H 60.0% O What is the empirical formula for the compound?...
