The oxygen forms a single bond to one hydrogen and a single bond to the other hydrogen... an oxygen has overall 6 valence-electrons, that means electrons, that could be used forming bonds... every bond is formed of two electrons... all hydrogens have one electron...
O.k., sounds complicated... nevertheless, read it again and calculated the number of valence-electrons the oxygen has after forming these two bonds... yes, 4 electrons are left... that means two not-binding molecular orbitals (with 2 electrons each) have to reach the energetically best orientation.
That's just like the oxygen would have four ligands... two hydrogens and two not-binding (but space occupying) orbitals... the best way is to position them tetraedrically... the oxygen and the hydrogens form a V, the oxygen and the orbitals form a V, too... (H-O-H in V-form, etc.), put the peaks of the two V's together (like a railroads-cross - the center is the oxygen). Then turn one V around 90 degrees... there you have the energetically best orientation with the largest distance between all ligands. If we now look at a water molecule, we do not see the orbitals, but only the two hydrogens... so, it seems to be an open triangle.

∙ 7y agoLife needs water and depends on the properties of water and those properties depend on the polarity of water. If water was non-polar, water would not be able to form hydrogen bonds and these bonds give water it's high specific heat (takes long to heat and stays hot longer once it is heated). It would not have surface tension (water could not go up trees, bugs could not stand on water and water would not stick to the sides of things). Ice would not float on liquid water (hydrogen bonds creates the crystal lattice so that ice has the unique property of being less dense than the liquid phase). For apex users : water would not be able to climb up inside animals

∙ 9y agoWater molecules in the bent shape are polar. If the molecule was linear, it would no longer be a polar because the bond dipoles between the oxygen and hydrogen would even out. Without polarity, many of water's properties would change, such as its use as a solvent.

∙ 9y agoWater is a bent molecule rather than linear. The reason for this bent shape comes from the electronegative nature of the oxygen atom. The electronegativity of oxygen creates a dipole moment in the molecule.

What would happen if you increased the temperature in water?
the water molecules would begin to move faster (an increase in kinetic energy). if the water reached 100 degrees celcius (212 degrees Fahrenheit), it will boil.
What would mix the best with water non polar molecules polar molecules fatty molecules symmetrical molecules?
Polar molecules are mixed better with water.
What molecule would mix best with water?
Polar Molecules
What molecules would you expect to dissolve in water polar covalent molecules ionic molecules nonpolar covalent molecules?
ionic molecules
What happens to the water molecules in a beaker as the water that is heated from 10 c to 90c?
The water molecules would speed up, but not to the point of boiling.
What would happen if you had a cell in the water and molecules were in the cell and some were out the cell what would most likely happen after a period of time?
what would happen if you had a cell in water and molecules were in the cell and some were out of the cell what would most likely happen after a period of time?
What would happen if a fatty acids in a cell membrane were polar molecules?
The cell would dissolve in water.
What would happen if the fatty acids in cell membrane were polar molecules?
The cell would dissolve in water.
What would happen if glycolsis did not happen in a cell?
If glycolysis could not happen in a cell, the cell would not produce ATP molecules.
What would happen to human blood if put in salt water?
If human blood is put in salt water, the water molecules in the human blood will lead to the lower concentration of water molecules. This process is called diffusion- water molecules going from high concentration to low concentration.
What would happen to the speed and energy of water particles during the evaporation phase?
The energy of water molecules is increased to allow evaporation.
What would happen if you increased the temperature in water?
the water molecules would begin to move faster (an increase in kinetic energy). if the water reached 100 degrees celcius (212 degrees Fahrenheit), it will boil.
What happen to water moulcule as heat is applied?
When heat is added to the water, the molecules move faster. When the water reaches the boiling point (100 Degree Celsius), the water molecules at the surface of the water would break apart with the other molecules and escape (evaporate). When they evaporate, the water molecules changes state and becomes water vapour.
What would happen if you stuck your head in a microwave?
The water molecules at the spot where the emitter is focused would become excited, eventually vaporizing and cooking the surrounding tissue.
Would a large body of water molecules have a stronger attraction to fewer molecules?
A large body of water molecules would typically not have a stronger attraction to fewer molecules. It would however attempt to pull smaller molecules toward it.
What would mix the best with water non polar molecules polar molecules fatty molecules symmetrical molecules?
Polar molecules are mixed better with water.
Why is the ink drop spread into the beaker of water?
The molecules in the drop of ink will diffuse through the entire beaker of water. This will result in a homogeneous solution because of diffusion. This will only happen if the ink is of similar density to water.
