Ice is less dense than water because of which type of bond?
Ice is less dense than water due to hydrogen bonding. When water molecules freeze into ice, the hydrogen bonds hold the molecules in a more spaced-out, lattice-like structure, causing ice to be less dense than liquid water.
Is potassium more reactive or less reactive then hydrogen?
potassium is more reactive because it has more outer shells of electrons than hydrogen. more outer shells means a weaker pull from the positive proton. this means it is easier to lose an electron with a weaker pull from the proton
Compare the densities of hydrogen oxygen and water?
Water is a compound and Hydrogen and Oxygen are elements. Elements are substances whose atoms all contain exactly the same number of protons. Water has a melting point over a hundred degrees above the boiling point of either Hydrogen or Oxygen. This is why water is mostly in its liquid form on earth's surface and Hydrogen and Oxygen are always found as gasses. Water is also one of the very few substances whose solid is less dense than its liquid. This is why ice floats.
What happens if you put hydrogen in water?
Not much! Some of it, a tiny amount, might bond to the water molecules, but as water already has its standard H2O composition, most extra hydrogen will simply bubble out, hydrogen being lighter than water. For details and discussion of hydrogen bonding with water, see Related Links below these advertisements. The solubility of hydrogen gas in water at 0oC is 0.0019 grams of hydrogen per kilogram of water. At 60oC, the solubility is 0.0012 grams of hydrogen per kilogram of water. That is a tiny amount that will dissolve in the water. The rest would simply bubble out as the previous answerer said. Also, most likely, the water would be already saturated with hydrogen since it was in contact with the atmosphere, which contains hydrogen; so unless you took steps to purge the hydrogen from the water to get water not already saturated with hydrogen, all of the added hydrogen would bubble out since the water would be already saturated with hydrogen.
Hydrogen bonds are weaker than the bond that holds hydrogen to oxygen in a water molecule?
Hydrogen bonds are weaker than covalent bonds. The bond between hydrogen and oxygen in a water molecule is a covalent bond, caused by the sharing of electron pairs between the two atoms. Hydrogen bonds are formed between a hydrogen atom of one molecule and an electronegative atom (like oxygen or nitrogen) of another molecule, and are weaker than covalent bonds.
Why does copper not liberate hydrogen on reacting with dilute sulphuric acid?
it is because hydrogen gas usually liberates when an acid reacts with metal
Why Cu does not liberate H2 gas from dilH2So4?
Copper (Cu) is below hydrogen (H) in the activity series of metals, which means it is less reactive than hydrogen. As a result, when copper is placed in dilute sulfuric acid (H2SO4), it is unable to displace hydrogen from the acid to liberate H2 gas. Only metals above hydrogen in the activity series can displace hydrogen from acids to form hydrogen gas.
Does water gave stronger hydrogen bond than hydrogen fluoride?
Hydrogen fluoride (HF) has a stronger hydrogen bond than water, as HF molecules have a greater electronegativity difference between the hydrogen and fluoride atoms compared to water molecules, resulting in a stronger attraction. This makes hydrogen fluoride a stronger hydrogen bonding compound than water.
Would it be easier to separate the sugar from the water or to split water into hydrogen and oxygen?
It is easier to separate sugar from water through physical processes like evaporation or filtration. Splitting water into hydrogen and oxygen requires a chemical process called electrolysis, which typically involves passing an electric current through water, making it more complex and energy-intensive compared to separating sugar from water.
Is there more hydrogen in salt water than in fresh water?
The molecule of water remain unchanged, and also the percentage of hydrogen.
Does hydrogen float in water?
if it is less dense than the water, it floats. Water can have different density.
Why is hydrogen bonding more extensive in water than hydrogen fluoride?
Hydrogen bonding in water is more extensive than in hydrogen fluoride due to the presence of two lone pairs on the oxygen atom in water, allowing for multiple hydrogen bonding interactions. In hydrogen fluoride, the fluorine atom has only one lone pair, limiting the number of hydrogen bonds that can form.
Why is the boiling point of water is higher than hydrogen fluoride?
The two hydrogen-oxygen bonds in a water molecule allow it to form more hydrogen bonds with adjacent molecules than hydrogen fluoride can with its one hydrogen-fluorine bond. As a result, water has a stronger attraction between molecules.
What substance has more hydrogen ions than pure water?
an acid has more hydrogen ions than water.
Why is hydrogen less dense than water?
At standard temperature and pressure (STP) hydrogen is a gas and water is a liquid.
How can you tell there is more oxygen in hydrogen peroxide than in water?
You can tell that there is more oxygen in hydrogen peroxide than in water because hydrogen peroxide has an extra oxygen atom compared to water. The chemical formula for hydrogen peroxide is H2O2, while the formula for water is H2O. This extra oxygen in hydrogen peroxide makes it a more oxidizing chemical compared to water.
How is the formula for water different than the formula for hydrogen peroxide?
Water is H2O. Hydrogen peroxide is H2O2. Hydrogen peroxide has one more oxygen atom per molecule than water. The extra oxygen is what makes it a peroxide. "Hydrogen oxide" would be water. The extra oxygen also makes hydrogen peroxide much more reactive than water due to the unstable oxygen-oxygen bond.
