WebAug 15, 2024 · Molecular substances tend to be gases, liquids or low melting point solids, because the intermolecular forces of attraction are comparatively weak. You don't have to break any covalent bonds in order to melt or boil a molecular substance. The size of the melting or boiling point will depend on the strength of the intermolecular forces. WebMar 21, 2024 · The higher biomass retention capacity of BFS may explain why F1 maintained greater methane productivity than F2, despite having a significantly smaller void volume (i.e., lower inoculum size). In contrast, the total methane production was largely comparable between R1 and R2 (<10% difference except at a WRR of 150 mL/d) due to …

The discussion of the DSC analysis must be revised (lines 252-258). The authors wrote: “Blue line represents the first run in temperature range from 0°C to 150°C with melting temperature (endothermic peak) at 132°C.
WebNearly all alkanes have densities less than 1.0 g/mL and are therefore less dense than water (the density of H 2 O is 1.00 g/mL at 20°C). These properties explain why oil and grease do not mix with water but rather float on its surface. Table 4.2. 1: Physical Properties of Some Alkanes. Molecular Name.
