A hydrocarbon of unknown formula C Hy was submitted to combustion analysis with the following results....
I want to use combustion analysis to determine the unknown formula of a hydrocarbon that is composed of only hydrogen and carbon. For 56.0 g of the hydrocarbon, I find that 189.2 g CO2 and 77.5 g H2O are produced. a. Write the reaction equation for the combustion of an unknown hydrocarbon CXHY. b. Using the information provided, determine the empirical formula of the hydrocarbon.
When 3.537 grams of a hydrocarbon, C,Hy, were burned in a combustion analysis apparatus, 11.96 grams of CO2 and 2.448 grams of H2O were produced In a separate experiment, the molar mass of the compound was found to be 78.11 g/mol. Determine the empirical formula and the molecular formula of the hydrocarbon. Enter the elements in the order presented in the question. empirical formula = molecular formula =

1. Complete combustion of 7.30 g of a hydrocarbon produced 22.4 g of CO2 and 10.7 g of H2O. What is the empirical formula for the hydrocarbon? Insert subscripts as necessary. 2. An unknown compound contains only C , H , and O . Combustion of 5.50 g of this compound produced 12.5 g CO2 and 5.12 g H2O . What is the empirical formula of the unknown compound? Insert subscripts as needed.
If there is an insufficient amount of oxygen, you can get incomplete combustion. If this occurred while analyzing the unknown samples from parts a, b, and c, describe what errors would occur while trying to determine the empirical formula. ***Please do NOT solve parts a,b,c!! I ONLY need help with the question above*** part a: A 10.00g unknown sample with a formula of CxHY was analyzed by combustion analysis. The sample produced 27.42g of CO2(g) and 22.46g H2O(g). Find the...
