THE EMPIRICAL FORMULA FOR THE PURE HYDROCARBON IS CH4
Explanation:
A pure hydrocarbon contains carbon and hydrogen
Percentage composition of carbon = 74.5 %
Percentage composition of hydrogen = 25.5
In order to calculate the empirical formula of this hydrocarbon, you follow these couple of steps.
write out the percentage composition and divide by the relative atomic mass of the respective constituents.
Carbon = 74.5 / 12 = 6.2083
Hydrogen = 25.5 / 1 = 25.5
Next is to divide the values by the lowest factor
Carbon = 6.2083 / 6.2083 = 1
Hydrogen = 25.5 / 6.2083 = 4.1
Next is to write the empirical formula:
C H4
In conclusion the empirical formula for the pure hydrcarbon is CH4
The Process Of Outgassing Help Layers of Earth To Form
Answer:
Explanation:
Energy can neither be created nor destroyed, but it does change its form. And not all forms of energy are usable and it gets dissipated as heat energy and sound energy. ... Moreover, the current sources or energy such as fuels are non-renewable in nature and are rapidly consumed. That is why we are facing energy crisis.
