Why do oxygen molecules move slowly than hydrogen molecules at the same temperature?
Two gasses at the same temperature have the same amount of average kinetic energy per molecule. Since an oxygen molecule has about 16 times the mass of a hydrogen molecule, it must move faster than a hydrogen molecule with the same kinetic energy.
This is based on the equation KE=1/2MV2

Is hydrogen peroxide a heterogeneous or homogeneous mixture?
Hydrogen Peroxide (H2O2) is a compound, and liquid at room temperature. It is NOT a mixture. However, at room temeprature it slowly decomposes to oxygen and water. 2H2O2 = 2H2O + O2 It the oxygen remains in solution in water then it is heterogeneous solution, NOT Mixture.
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 happens to molecules when they are cooled down?
When molecules are cooled down, they lose energy and move more slowly, causing them to come closer together and form a solid or liquid state, depending on the temperature.
Why is the permanganate solution added slowly to hydrogen peroxide solution?
To avoid a violent reaction.
What happens to a liquid when it is heated slowly?
When a liquid is heated slowly, its temperature will gradually increase, causing the molecules within the liquid to move faster. Eventually, the liquid will reach its boiling point, where it will vaporize and turn into a gas.

Why is hydrogen more stable than oxygen in car tires?
have you ever seen videos of a hydrogen bomb that's why lol. but you don't use pure oxygen cause that's poisonous and extremely flammable you use air which is (70% nitrogen, 29% oxygen 1% etc..
What moves slowly through thermal energy?
Molecules in a material move slowly through thermal energy. As temperature increases, the kinetic energy of the molecules increases, causing them to move faster.
How solid changes to liquid?
meltingSOLID ============> LIQUIDto answer this question let us take ice as an example.Ice begins as water which is two parts hydrogen and one part oxygen. Unlike other similar substances though water is a liquid at room temperature while the other similar substances are gases at room temperature which makes water a very interesting subject. Water is a liquid at room temperature because the hydrogen atoms are attracted to the oxygen atoms that make up water. Because of this the hydrogen atoms "connect" to the oxygen atoms. This is called a hydrogen bond. This keeps the water from becoming a gas at room temperature. When the water is put on the stove to boil though we see "steam" coming from the pan we put it in. This is the gas form of water. Water becomes a gas when put over high temperature because the heat is giving the molecules more energy to move around causing the hydrogen bond to break making the liquid a gas.If this is the case with the liquid form of water becoming a gas it is the exact opposite of it becoming a solid. Water turns into a solid when put in freezing temperature. It becomes a solid because the molecules are slowing done and soon they get so slow they hardly move at all. If kept in the freezing temperature then it will stay a solid. But when taken out slowly the molecules will start to get warm again causing the solid to become a liquid because the molecules are moving again and are connecting together to make the hydrogen bond I spoke of earlier. I hope that has answered your question.

Are solvent cohesive and temperature stabilization properties of water due to its hydrogen bonds?
Yes, the solvent cohesive and temperature stabilization properties of water are indeed due to its hydrogen bonds. The hydrogen bonds between water molecules give it a high surface tension, allowing it to stick to itself (cohesion) and other substances (adhesion). Additionally, the hydrogen bonds also contribute to water's high specific heat capacity, which helps to stabilize temperature by absorbing and releasing heat slowly.
Does boiling water have oxygen in it?
No,boiling water does not have oxygen . Cold water molecules move slowly meaning there is space between the molecules for more oxygen to dissolve. Hot water molecules move rapidly meaning the space between the water molecules is less avalible for the oxygen molecues to dissolve into.
What is the charge of hydrogen peroxide?
As H2O2 it is uncharged , but rather unstable., and will slowly decompose to water and oxygen.
Why do plant turn Yellow?
The chlorophyll molecules slowly dies as the temperature slowly lowers. Which causes other colours of the accessory and other pigments to become visible.

Why the water absorbs are release heat slowly?
strong hydrogen bonds between the molecules of water. hydrogen bond is an intermolecular bond between oxygen (which has high electron density) of a H2O molecule with hydrogen atoms (which has high positive charge density) that attracts oxygen atom with opposite charge of another H2O. hydrogen bonds in water molecules are more numerous than other hydrogen bonds in HF ,for example, due to the higher number of lone electron pairs of oxygen that results in water having higher boiling point.
What happens to molecules when they are cooled down?
When molecules are cooled down, they lose energy and move more slowly, causing them to come closer together and form a solid or liquid state, depending on the temperature.
