CHEM 1201 : SI Final Exam Review
Document Summary
Plinko combustion analysis: a 1. 50 g sample of hydrocarbon undergoes complete combustion to produce 4. 40 g of co2 and 2. 70 g of h2o. What is the empirical formula of this compound: the element zinc consists of five isotopes with masses 63. 929, 65. 926, The relative abundances of these five isotopes are 48. 89, 27. 81, 4. 110, 18. 57, and 0. 62 percent, respectively. From this data, calculate the average atomic mass of zinc: an elemental ion has 34 protons, 36 electrons, and 44 neutrons. 11/30/11: a compound of azulene is composed of 93. 71% c and 6. 29% h. what is the empirical formula, what is the molecular formula of azulene, knowing the empirical formula is. C5h4 and the molar mass is 128. 16 g/mol: what mass of propane is combusted if 42. 1g of steam is produced, how many moles of ammonia can be obtained from the reaction between.
