Complete combustion of 6.00 g of a hydrocarbon produced 18.4 g of CO2 and 8.78 g of H2O. What is the empirical formula for the hydrocarbon? Insert subscripts as necessary.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Complete combustion of 6.00 g of a hydrocarbon produced 18.4 g of CO2 and 8.78 g of H2O. What is the empirical formula for the hydrocarbon? Insert subscripts as necessary.
Let in compound number of moles of C and H be x and y respectively
Number of moles of CO2 = mass of CO2 / molar mass CO2
= 18.4/44
= 0.418
Number of moles of H2O = mass of H2O / molar mass H2O
= 8.78/18
= 0.487
