( it should be easy ) [ the first person to answer it correctly will be marked as the brainliest ]

Answer 1

Answer:

Chemical properties:The organic matter in coal consist of mainly carbon,hydrogen,oxygen,nitrogen,sulfur and some other elements.Carbon,hydrogen and oxygen account for more than 95% of the organic matter in coal

physical properties:the physical structures and properties of various coal types are described in terms of the most commonly used physical characterization techniques, including X-ray diffraction, X-ray scattering, surface area, and porosity measurement techniques

Answer 2

Answer:

Result of chemical composition and physical characteristic (proximate, ultimate analysis and calorific value of coal and mangrove wood were as follow: coal from Kaltim Prima Coal were moisture: 16.11%, ash: 3.77%, volatile matter: 43.10%, fixed carbon: 37.01%, carbon content: 44.86%, sulfur content: 0.130%
