【Daily Question】Chemical Engineering Principles 431: Composition of Coal (September 19)
Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope you will give it your active support! Wishing you a happy Christmas! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying to the post, and the topic will be closed after 1 day ! To encourage continued participation from everyone this year! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: What are the five main elements that make up the combustible organic compounds in coal, as determined by its elemental analysis? The organic matter in coal contains five elements: carbon, hydrogen, oxygen, nitrogen, and sulfur
The elemental composition of coal consists mainly of five elements, namely carbon, hydrogen, oxygen, nitrogen, and sulfur.
Just saw it today haha; elemental analysis: C, O, H, S, N. Industrial analysis: moisture, volatile matter, ash, fixed carbon
Carbon, hydrogen, oxygen, nitrogen, and organic sulfur
The five elements H, O, C, N, and Ca
Carbon, hydrogen, oxygen, nitrogen, and organic sulfur
The organic matter in coal consists mainly of five elements: carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and sulfur (S).
