Icebergs float on water because the underlying liquid water has a higher density than the iceberg. Liquid water itself has ...

For instance, the density of ethanol is about 0.789 g/cm³, making it less dense than water. Viscosity: Alcohols have higher viscosities than hydrocarbons due to intermolecular hydrogen bonding. As the ...

Many are still betting on green hydrogen as an essential component for fueling the transition to clean mobility and energy storage. This is especially true for heavy-duty vehicles such as buses, ...

ORNL researchers created a durable zeolite catalyst that converts methane and carbon dioxide into syngas without degradation ...

Hydrogen, for example, can be used as a clean fuel or as a feedstock for ammonia to create fertilizer. Methanol, an alcohol that can ... making chemical bonds easier to break and create.

Finalising the syllabus for the National Eligibility-Entrance Test Undergraduate (NEET-UG) 2025 examination, the ...

By systematically replacing the alcohol group with acid groups ... This contrast suggests that water disrupts the intercomponent hydrogen bond network in glycerol, significantly speeding up its ...

The dot and cross diagram shows that a water molecule is made up of one oxygen atom joined to two hydrogen atoms ... atoms can form three covalent bonds, so a triple bond forms between them.

Hydrogenolysis of waste polyolefins often produces excessive methane under low hydrogen pressure. Here, by using a dilute RuPt alloy, the authors successfully prevent sequential C–C bond ...
