Name a molecule that does not dissolve well in water?
oil does not dissolve at all in water.
Why evaporation of water a physical change and not chemical?
Water in solid form, as ice, is chemically H2O In liquid form it is also only H2O In gas form, as water vapour, it is still only H2O, albeit that the molecules/atoms have greater activity and that the volume is much greater than that of water in the liquid state.
How do hydrogen bonds happened between neighboring water molecules?
The oxygen in the water molecule is Partially negative and the Hydrogen in the water molecule is partially Positive . Thus they bond up to form Hydrogen Bond.
What polar molecule made from 1 oxygen and 2 hydrogen atoms that is required by all living things?
This is a water molecule H2O
Is water a mixture or a compound is science?
Water is a pure compound -- all of it is one kind of molecule: H2O.
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water cannot be separated into hydrogen and oxygen by boiling. Boiling is a physical change which means the molecule doesn't change at all--liquid water and water vapor are both H2O. Water can be separated into hydrogen and oxygen using electricity, this would be a chemical change.
Can well water change over time?
Yes, it changes all the time.
What is a H20 polar molecule?
It's just regular old water. All water is polar because the molecule has a dipole.
Name a molecule that does not dissolve well in water?
oil does not dissolve at all in water.
Dose the weight of water change if you add a fish?
If there is no overflow of water, then the container's over-all weight goes up by the weight of the fish. The weight of the water itself doesn't change.
What is the smallest particle of water called with the formula H2O?
Molecule
What is the over all structure of the DNA molecule?
double helix (:

Why toluene is insoluble to water?
Toluene is an aromatic hydrocarbon and like all hydrocarbons is a non polar molecule. Water is a polar molecule. The rule of dissolving is that non polar cannot dissolve in polar
What molecule is in photosynthesis sugar oxygen water or nitrogen?
All of them are not. It is the glucose.
How do hydrogen bonds happened between neighboring water molecules?
The oxygen in the water molecule is Partially negative and the Hydrogen in the water molecule is partially Positive . Thus they bond up to form Hydrogen Bond.
What are all the methods to separate the H2 and O2 from water molecule?
Probably the most straightforward is electrolysis of the water.
