What makes water so different from other small molecules that have a similar mass, such as methane (CH4), carbon monoxide (CO), and hydrogen sulfide (H2S), all gases? a) Water is the 'universal solvent'; it has the ability to dissolve everything. b) Wat...
Re: Why does water have a greater polarity than ethanol? « Reply #1 on: May 02, 2021, 03:25:43 AM » You got it reversed.It is not dominating interactions between molecules that tells us whether the molecule is polar, or not, it is whether the molecule is polar or nor not that...
Water also contains dissolved oxygen (O2) molecules. All electronics contain PCBs (printed circuit boards). PCBs have metals like Copper, Gold and Palladium as conductors. When exposed to water, aredox reactionoccurs where the metal loses electrons and forms a metal-oxide layer. Overtime, this ...
Water is the one compound that humans have designated as necessary for life to exist on this or any planet. So far, we might be correct. Water makes up to 60% of an adult humans body mass. In some organisms it is as high as 90% of their body mass....
Structure of DNA: DNA is composed of two antiparallel strands of nucleic acids that are held together by hydrogen bonds between the nitrogenous bases of opposing strands. The backbone of each strand of DNA is composed of alternating phosphate and deoxyribose molecules. ...
MALE PROFESSOR: We think meteors that crashed into the Moon, or tails of passing comets, may have introduced water molecules.Any water molecules that found their way to the floors of craters near the Moon's poles, that water would be perpetually frozen because the floors of those craters are...
DMolecules are associated by hydrogen bonding Submit DHydrogen bonding Submit DIncrease sharply from HF to HCI and then decrease regularly with increase of relative molecular mass. Submit Why does water have high boiling point? View Solution
molecules possess only translational kinetic energy Answer and Explanation:1 According to the Kinetic Theory of Gases molecules have the average kinetic energy of {eq}\overline{KE}=\frac{1}{2}m\overline{v^{2}}=\frac{3}{2}k_{B}... ...
you need to break the surface of the water and submerge into it. At this point, we are faced with a pesky little problem calledsurface tension. Cohesive forces between water molecules are stronger at the surface. This is why it is harder to break the surface of water than to move w...
During the evening and night, the earth becomes colder, but our air temperature might be slightly higher. When the humidity is close to 100 percent, water molecules, called vapor, begin to collect droplets and fog is formed. Spring, summer and early fall mornings are usually the time fog is...
