What happens when oxygen is prepared from hydrogen peroxide without adding a catalyst?
Hydrogen peroxide purchased from a store or science supply house has been stabilized so that expected loss due to spontaneous decomposition into oxygen and water is less than 3% per year. Without adding a catalyst, you will have to wait a very long time to collect the oxygen from a sample of hydrogen peroxide.
What causes water to display such strong hydrogen bonding?
When you put hydrogen and oxygen together, the electrons spend most of their time on oxygen since it is more electronegative than hydrogen. This causes there to be a "partial charge" on both hydrogen and oxygen. Since oxygen has the electrons spending more time on it, it is more negative than hydrogen. So in H2O, the hydrogens are slightly more positive than the oxygens. When water molecules come near each other, the slightly positive hydrogens are then attracted to the slightly negative oxygens, and you end up having hydrogen bonding.
How water is physically different from the elements that makes up the compound?
Water is h20 which is 2 oxygen atoms and one hydrogen atom to every bit of water. hydrogen and oxygen are a gas at the time oxygen is made...well as far as i know anyways...but I'm just a very intellegent year 8 student from London!
True or false Water is an example of a polar molecule?
True. Water is a polar molecule because it has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom due to differences in electronegativity. This polarity allows water to form hydrogen bonds with other water molecules.
What happens when shared electrons between hydrogen and oxygen spend more time orbiting the oxygen than the hydrogen and what effect does this have on water molecules?
If you think of it in terms of time, the electrons always spend more on the oxygen. This creates polar bonds, and as the molecule is not symmetrical, it means that the whole molecule is polar.
Why dont hydrogen and oxygen atoms share electrons equally in a water molecule?
Because the electronegativity of oxygen is about 3.5 and the electronegativity of hydrogen is about 2.5. So, the electrons shared in this polar covalent bond spend more time in the orbitals around oxygen that the orbitals around hydrogen giving the molecule slightly negative and positive ends.
What is hydrogen peroxide broken down into?
Hydrogen peroxide can break down into water (H2O) and oxygen (O2) when exposed to light or heat. This decomposition reaction occurs naturally over time, especially in the presence of certain catalysts like metals.
In a water molecule shared electrons spend more time around the oxygen atom than the hydrogen atoms. As a result the oxygen atom is?
In a water molecule, shared electrons spend more time around the oxygen atom than the hydrogen atoms due to oxygen's higher electronegativity. This unequal sharing of electrons creates a partial negative charge (δ-) on the oxygen atom and a partial positive charge (δ+) on the hydrogen atoms. Consequently, the oxygen atom is considered to be more electronegative and exhibits a polar character, contributing to water's unique properties such as its solvent capabilities and high surface tension.
Can cars run on water instead of gas?
No. To convert it to "Hydrogen" requires a fuel cell and appropriate oxygen / hydrogen separator components. Technology has not reached that point of evolution at this time.
How long do you have to wait to get in the pool after adding sodium hydrogen bi carbonate?
You should wait about 6 to 8 hours before getting into the pool after adding sodium hydrogen carbonate. This will allow time for the chemical to dissolve and mix thoroughly in the water, ensuring that it is safe for swimming.
Why water is a polar molecule?
Oxygen is more electronegative than hydrogen - meaning the electrons they share will spend more time near the oxygen. This causes the oxygen to have a partial negative charge, and the hydrogens to have a partial positive charge - making water polar.
Why are the bonds in water described as polar covalent?
The bonds in water are described as polar covalent because oxygen is more electronegative than hydrogen, causing the electrons to spend more time around the oxygen atom. This unequal sharing of electrons creates a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom, making water a polar molecule.
