Analysis of Chemical Composition

To determine the chemical composition of an unknown compound, we can perform a combustion analysis and analyze the products formed.

Combustion analysis involves burning a sample of the unknown compound to determine the amount of carbon, hydrogen, and oxygen present based on the resulting products, such as carbon dioxide and water.

In the given data, the combustion of 3.50 g of the unknown compound produced 5.13 g of carbon dioxide and 2.10 g of water. From this information, we can calculate the moles of carbon and hydrogen in the original sample by using stoichiometry and the molar masses of the compounds involved.

The key steps in determining the chemical composition of the unknown compound include converting the masses of carbon dioxide and water to moles, identifying the ratios of carbon, hydrogen, and oxygen in the compound, and ultimately deducing the empirical formula of the compound.

By following these steps and applying relevant chemical principles, the composition of the unknown compound can be successfully determined, providing valuable insights into its structure and properties.
