What is the mole ratio of oxygen to carbon dioxide in the following equation? {eq}C_3H_8 + 5O_2 \rightarrow 3CO_2 + 4H_2O {/eq} a. 2:2 b. 3:5 c. 5:3 d. 10:6 Mole Ratio: It is a ratio comparing th...
Of importance in determining the final structure and chemistry of the carbon is the presence of the non-carbon atoms: oxygen, hydrogen, and in many cases, nitrogen, phosphorus, or sulfur. In the case of the oxygen, the carbon/oxygen ratio factors heavily into the final structure. The C-O...
2c), whereas purging the system with N2 to remove dissolved oxygen significantly reduced the yield to 465 µmol g−1 h−1. These results underscore the vital role of dissolved oxygen in the photocatalytic production of H2O2 by CQDs-NH. Additionally, with sufficient N2 to eliminate the ...
Here, we report the preparation of Fe3O4-dopped carbon cubosomes (named SP-Fe3O4-C) with a single-network plumber’s nightmare structure (i.e., single primitive (SP) bicontinuous topology). The synthetic strategy employed polymer cubosomes (PCs; cubosomes generally refer to colloidal particles...
Electrical conductivity (σ) of the GCBs was determined by a four-point probe tester (DMM7510, Keithley, USA) with a probe spacing of 1 mm at room temperature, from the following equation52,53,54,55: $${\rm{\sigma }}=1/{\rm{\delta }},{\rm{\delta }}={{\rm{R}}}_{{\rm...
Carbon products are obtained by heating coal (to give coke), natural gas (to give blacks), or carbonaceous material of vegetable or animal origin, such aswoodor bone (to give charcoal), at elevated temperatures in the presence of insufficient oxygen to allowcombustion. The volatile by-products...

Introduction Spontaneous coal combustion is one of the five major disasters in coal mines [1,2,3], which restricts the safe and efficient exploitation and utilization of coa...
This confirms that Sn provides surface oxygen-containing species that react with intermediates produced during an oxidation reaction. It is apparent that the size effect promotes the higher catalytic activity of Pd-the Sn/CNFs electro-catalyst for ethanol oxidation [45,46]. Since Pd-Sn/CNFs ...
