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.
The anomalous physical properties of water can be attributed to its unique hydrogen bonding structure. Water molecules are able to form multiple hydrogen bonds with neighboring water molecules, resulting in a high surface tension, ability to dissolve a wide range of substances, and expanded volume when frozen. These properties are key to water's role as a universal solvent and essential for life processes.
Lemonade expands more than water when frozen due to its sugar and other solute content, which disrupts the formation of ice crystals. Water typically expands when frozen because of the unique hydrogen bonding that creates a structured lattice. However, the presence of solutes in lemonade lowers the freezing point and alters the density, causing it to expand more as it freezes compared to pure water. This results in a greater volume change during the freezing process.
The volume of hydrogen gas compares to the volume of oxygen gas based on their stoichiometric ratio in chemical reactions, particularly in the formation of water. In the reaction 2H₂ + O₂ → 2H₂O, two volumes of hydrogen gas react with one volume of oxygen gas. This means that for every two volumes of hydrogen, there is one volume of oxygen. Therefore, the volume of hydrogen gas is twice that of oxygen gas in this specific reaction.
By volume, hydrogen accounts for around 0.000055%.
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.

The difference in volume of solids from step 1 to 5 can be attributed to changes in the intermolecular bonding. As intermolecular bonding changes from weaker forces (like London dispersion forces) to stronger forces (like hydrogen bonding or ionic bonding), the particles are packed more closely together, resulting in a decrease in volume. Conversely, weaker intermolecular forces allow the particles to be more spread out, leading to an increase in volume.
It increases because water expands when frozen, this occurs becasue of hydrogen bonding.THANKS FOR USING WIKI.ANSWERS.COM
Freezing typically does not affect the weight of an object. When an object is frozen, it undergoes a phase change from liquid to solid, but its mass remains the same. However, freezing can cause a slight expansion in volume due to the change in state.
If you mean hydrogen in elemental form, it's darn near zero.
The amount of hydrogen produced will not change since the production of hydrogen gas in the reaction is determined by the number of moles of calcium reacting, which remains constant at 0.1 mol. The volume of water does not affect the amount of hydrogen gas produced as long as the stoichiometry of the reaction is maintained.
Water expands slightly when if freezes (due to hydrogen bonding) and the resulting ice is less dense than water.(Actually, the water still weighs the same- it just takes up more space when frozen)
To make a 5 volume developer, you would mix equal parts of 10 volume developer (3% hydrogen peroxide) and distilled water. This will dilute the concentration of hydrogen peroxide to achieve a 5 volume strength (1.5% hydrogen peroxide).
By volume, hydrogen accounts for around 0.000055%.
The strength of a solution may be described as a percentage or volume, where 1% hydrogen peroxide releases 3.3 volumes of oxygen during decomposition.Thus, a 3% solution is equivalent to 10 volume and a 6% solution to 20 volume, etc. Answer taken from Wikipedia 19/01/2009
