That is the depiction of hydrogen gas and, charge aside, where could you fit a definition of polarity, having two different ends, into this depiction.
If water were a less polar molecule, its surface tension would likely decrease. Surface tension in water is primarily due to the hydrogen bonds formed between water molecules, which are a result of water's polarity. A less polar molecule would not form as strong hydrogen bonds, leading to weaker surface tension.
Water is more polar than 2-propanol because it has a greater difference in electronegativity between oxygen and hydrogen atoms, leading to a larger dipole moment. 2-propanol also has a dipole moment due to the hydroxyl group, but it is less polar than water.
Water is a polar molecule because it has a bent shape with oxygen being more electronegative than hydrogen, creating an uneven distribution of charge. This results in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms, making water a polar molecule.
Oil has less particle attraction than water because oil molecules are nonpolar, with no overall charge, resulting in weaker intermolecular forces. Water molecules, on the other hand, are polar and exhibit stronger hydrogen bonding, giving water higher particle attraction.
Kerosene has less surface tension than water because its molecules are less polar and can't form hydrogen bonds as easily as water molecules. This results in weaker intermolecular forces between kerosene molecules at the surface, leading to lower surface tension.
Water is more polar than ethanol. This is because water has stronger hydrogen bonding due to the presence of more hydrogen-bonding sites (two hydrogen atoms and one oxygen atom), making it a better solvent for polar substances. Ethanol is also polar but has weaker hydrogen bonding compared to water.
Water is polar molecule since oxygen has a higher electronegativity than hydrogen.
Water is polar molecule since oxygen has a higher electronegativity than hydrogen.
If water were a less polar molecule, its surface tension would likely decrease. Surface tension in water is primarily due to the hydrogen bonds formed between water molecules, which are a result of water's polarity. A less polar molecule would not form as strong hydrogen bonds, leading to weaker surface tension.
Thymol is considered to be moderately polar due to the presence of hydroxyl (OH) groups, which can participate in hydrogen bonding. It is more polar than non-polar compounds like hydrocarbons, but less polar than highly water-soluble compounds.
Water is more polar than 2-propanol because it has a greater difference in electronegativity between oxygen and hydrogen atoms, leading to a larger dipole moment. 2-propanol also has a dipole moment due to the hydroxyl group, but it is less polar than water.
Water is polar molecule. Since oxygen has a higher electronegativity than hydrogen.
Pheophytin and Chlorophyll are similar in there makeup. The difference between the two is that the magnesium ion is replaced by hydrogen making it less polar.
less denser than
No, water molecule (H2O) is more polar than ammonia (NH3) because of the greater difference in electronegativity between oxygen and hydrogen atoms in water molecule compared to nitrogen and hydrogen atoms in ammonia molecule. Water has two polar covalent bonds while ammonia has only one.
Most salts will dissolve more readily in water than ethanol, so in ethanol the solid can crystallize out at lower concentrations. Also ethanol has the added benefit of being more easily removed by evaporation.
if it is less dense than the water, it floats. Water can have different density.
