How does hydrogen bonding affect the volume of frozen water and why?

The crystal structure of frozen water the commonly occurring "hexagonal" form, "Ice one" consists of oxygen atoms surrounded by 4 hydrogen atoms. the OH bond angle is tetrahedral but two atoms are closer at 101 pm (in molecular water they are slightly closer at around 98pm.) The bonding is therefore best described as two covalent and two hydrogen bonds.
This is a rather open structure and the oxygen atoms are further apart in the solid than they are on average in the liquid. This explains why ice is not as dense as liquid water and therefore floats. Ice that forms quickly is amorphous with only short range ordering.

Why do water exist in liquid form and hydrogen sulphide exist in gaseous form?
Oxygen (O) is more electronegative than sulfur (S). This means that H2O more polar than H2S. This means that the forces of attraction between H2O molecules is grater than that in H2S molecules, making it harder to separate them from one another to turn it into a gas.
What percentage of hydrogen is in earth's atmosphere?
By volume, hydrogen accounts for around 0.000055%.
What evidence in the Hoffman apparatus demonstration indicates the ratio of water's components?
The volume of hydrogen is double the volume of oxygen.
In what volume ratio do hydrogen gas and oxygen gas react to form water?
Approximately twice as much volume of hydrogen as of oxygen: Both gases are diatomic and nearly ideal at normal temperature and pressure, and the atomic ratio of hydrogen to oxygen in water is 2.
Ice melts with contraction in volume?
Actually its bcoz of hydrogen bond
When water is further cooled down its volume starts increasing and its density decreases why is it so?
Hydrogen bonding !
What property causes water to from droplets?
cohesion (hydrogen bonding intermolecular forces) and the fact that surface area per unit volume is a maximum in a sphere.
How does the volume of a kilogram of water change when it freezes ice?
It increases because water expands when frozen, this occurs becasue of hydrogen bonding.THANKS FOR USING WIKI.ANSWERS.COM

How many volumes in hydrogen peroxide?
The volume measure used in hydrogen peroxide refers to the volume of oxygen that it produces
What is perhydrol?
30% of weight by volume(w/v) hydrogen peroxide or 100 volume strength hydrogen peroxide is perhydrol.
The solid acid is dissolved in 100 mL of deionized water followed by 10 mL ethanol How does this added volume affect?
The added ethanol will not affect the pH whatsoever, due to the fact that ethanol cannot donate hydrogen ions or accept them. The added volume will, however, not affect the molar mass of the acid that you will report from the analyses. You use the volume of base that is used to titrate the acid to find the moles of acid and base at stoichiometric point so the added volume will not affect the molar mass.
What percentage of hydrogen is in earth's atmosphere?
By volume, hydrogen accounts for around 0.000055%.
What are the signs of fluid volume excess?
pedal edema, hypertension, bonding pulse
What is molar volume of hydrogen at stp?
24.5
What is the volume of hydrogen gas when it is occupied by it's one equivalent at S.T.P.?
The molar volume of hydrogen is approx. 22,7 L at 100 kPa and 0C.
Why density of ice is less than water density?
Water has an unusual property that it expands as it freezes. This is due to the crystalline formation in conjunction with its hydrogen bonding. Since it expands, volume is larger. Density = mass / volume. Dividing by a larger number gives a smaller answer for the density. Water is most dense at 4 degrees Celsius.
