Why does the oxygen atomhave more electrons surrounding it than a hydrogen atom?
A hydrogen only has one valence electron, while oxygen has 6.
What chemicals were the products in the reaction in producing of hydrogen and oxygen gases?
This question answers itself. The products of a reaction PRODUCING hydrogen and oxygen are, well, hydrogen and oxygen!If you are asking what hydrogen and oxygen are made FROM, than the REACTANT is water. If a voltage is applied to water, hydrogen and oxygen gas are made.If you are asking what the product of a reaction is when hydrogen and oxygen are the REACTANTS, then the answer is also water.See the Related Questions for more information to the left of this answer.
The type of compound that contains much more carbon and hydrogen than oxygen?
One such type is hydrocarbons, which contain only hydrogen and carbon with no oxygen at all.
What is cheaper liquid oxygen or luquid liquid hydrogen?
liquid hydrogen is cheaper than liquid oxygen
What makes regions of a water molecule more positive then negative?
Electronegativity differences.There are more protons in an oxygen atom than in a hydrogen atom, so any electrons being shared between them (as in the covalent bond) are more likely to be near the oxygen atom than the hydrogen atoms.This results in a slight net negative charge surrounding the oxygen atom, and slight net positive charges surrounding the hydrogen atoms.
Is hydrogen more than oxygen in universe?
Yes, there is more Hydrogen than anything else in the universe. Most molecules which contain Oxygen also contain Hydrogen, and there is usually more Hydrogen than Oxygen within the molecule already, for example Water, H2O (There are exceptions, such as Oxygen, O2 and Ozone, O3)
Is hydrogen more abundant than oxygen in air?
No
Which element in H20 is more electronegative?
Oxygen is more electronegative than hydrogen.
Oxygen or hydrogen what is largest in earth?
Oxygen is more abundant than hydrogen. In fact it is the most abundant element on Earth.
Why if sucrose is 51.5 percent oxygen by mass and only 6.4 percent hydrogen by mass is there twice as many hydrogen atoms than oxygen atoms?
Oxygen atoms weigh more than Hydrogen atoms.
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.
How can you tell there is more oxygen in hydrogen peroxide than in water?
In 1 mole of water, the total amount of oxygen is only 16g. But the amount of the same in 1mole of Hydrogen peroxide is 32g. So more oxygen is present in hydrogen peroxide than in water.
How percentage of oxygen is more in water than hydrogen?
This is true for mass-%. Oxygen is 16 times heavier than hydrogen, that outfigures the double elemental ratio for hydrogen to oxygen (2:1) by factor 8 times.
Why is the bond between hydrogen and oxygen in a water molecule is more polar than the bond between hydrogen and nitrogen in a ammonia molecule?
Oxygen has a higher electronegativity than nitrogen does, so when sharing electrons with hydrogen, the sharing is more uneven in the case of oxygen than it is with nitrogen. Oxygen, in other words, will attract electrons more strongly than nitrogen does and therefore will wind up with a more negative charge (hydrogen, which supplies the extra electrons to the oxygen, has a correspondingly higher positive charge).
What is more polar a carbon hydrogen bond or a carbon oxygen bond?
A carbon-oxygen bond is more polar than a carbon-hydrogen bond, because the difference in electronegativity between carbon and oxygen is greater than the difference in electronegativity between carbon and hydrogen.
Is hydrogen more soluble in water than oxygen?
YES. Oxygen is more water soluble than the Hydrogen, becoz as we see that the aquatic life is sustained only due to the presence of the oxygen in the water.
What 4 elements account for more than 95 percent of the human body?
