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

What is in wood that makes it burn slowly?
it is the molecules they burn slowly and not very fast
How does temperature affect molecules in a liquid?
Molecules in a liquid are engaged in random thermal motion; they move around at random, bouncing off each other constantly. The temperature measures the amount of this motion. At higher temperatures, they are moving faster. At lower temperatures they move more slowly. Of course, at some point you also get phase changes. Increase the temperature sufficiently and the liquid will boil; decrease it sufficiently and (with the exception of helium) it will freeze.
How fast does mothball sublime?
depends on temperature. Very slowly at room temperature.
Why is the permanganate solution added slowly to hydrogen peroxide solution?
To avoid a violent reaction.
Can an apple break down hydrogen peroxide?
Yes it can. I did it in science class just today, and it works. It happens slowly but it does break down hydrogen peroxide.
What measurement can move rapidly or slowly molecules around?
Temperature
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.
Why the reaction between hydrogen and chlorine is very slow at room temperature?
Because hydrogen molecule is very stable and it is because of high dissociation enthalpy of hydrogen molecule, it reacts slowly with chlorine at room temperature.
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.
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.
Why is burning wood a exothermic reaction?
It burns slowly (reaction with oxygen at lower rate) at relatively low temperature (150oC). In a good fire place or a funeral pile temperature has risen and flames will appear, can grow to more than 10 metres high (forest fires!)
How can you produce oxygen in the lab?
You can electrolyze water to form O2 and H2 gas.See the Web Links for more information about how to do this.Be CAREFUL! Both pure oxygen gas and hydrogen gas are HIGHLY EXPLOSIVE!
What is a scenario for increasing temperature influence a chemical change?
At room temperature, magnesium and oxygen react very slowly. However, when you burn the magnesium, it will rapidly combine with oxygen in the air to form magnesium oxide, MgO.
Why do plant leaves 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.
Does sound travel more slowly through a given medium with a low temperature or high temperature?
Sound travels more slowly through a medium when it is at a low temperature because in a low temperature the molecules move slower and in a high temperature the molecules move faster. For Example: ice that is frozen and boiled water in ice the water doesn't move as fast so the molecules were slower than in the boiled water. HOPE I HELPED YOU!!
