Can HCl form a hydrogen bond? Is metallic bonding an intermolecular force? Can cellulose form hydrogen bonds with water? What is an important application of hydrogen bonding? Can H2S form hydrogen bonds? Does H2O have a dipole moment?
describes the exact number of each constituent atom present in one molecule of the compound. For example, the ammonia formula of {eq}\rm NH_3 {/eq} shows 1 nitrogen atom paired with 3 hydrogen atoms. Sometimes the molecular formula may have a net charge, if the species is a compound io...

Those investing in them definitely want batteries to be, but battery-electric vehicles have their limitations too. In addition to the energy density differences as mentioned, the infrastructure needed to make sure every household can charge at or near their home is nowhere near ready. Plus, ther...
ATP + H2O --> ADP + PO4. Examples of such molecular motor proteins include, transport motors (such as myosin, kinesis, and dyenin) which use ATP hydrolysis to power directed motion, helicases which use ATP hydrolysis to unwind DNA, and ion pumps (such as the Na/K pump) which use AT...
The atoms share electrons, but they don’t share those electrons evenly -- the oxygen ends of a CO2 molecule have a slight negative charge. Water molecules are attracted to these polar areas, allowing CO2 to dissolve in water. The Dissolution Process Carbon dioxide molecules must first pass ...
