What else can I help you with?
What is heavier Hydrogen gas or oxygen gas How do you know?
Oxygen is heavier as it has a mass number of 16 whereas hydrogen has a mass number of 1. Both form diatomic molecules (molecules of two atoms) making the formula masses 32 for oxygen and 2 for hydrogen.
What are the important elements in carbohydrates?
You have three elements in carbohydrates. Carbon, hydrogen and oxygen. It is interesting to know the composition of the glucose. When two molecules of glucose that get attached to each other, you get one molecule of water out.
How do you know if your hydrogen generator is working?
When water breaks their bonds you will see vinyls forming on the electrodes these bubbles are a combination of hydrogen and oxygen. At the top of the apparatus you siphon off the hydrogen and lower you siphons off the oxygen. Giving you the two seperatr molecules
Why does hydrogen bonding exists between water molecules but not between hydrogen sulfide molecules?
Hydrogen bonding in water molecules exists due to the large electronegativity difference between hydrogen and oxygen, allowing a strong dipole-dipole interaction. Hydrogen sulfide lacks this strong electronegativity difference between hydrogen and sulfur, resulting in weaker van der Waals forces instead of hydrogen bonding.
What elements are contained in each macromolecule?
Carbohydrates consist of carbon, hydrogen, and oxygen; lipids consist of carbon, hydrogen, and oxygen; proteins consist of carbon, hydrogen, oxygen, and nitrogen; nucleic acids consist of carbon, hydrogen, oxygen, nitrogen, and phosphorus.
Can lead be extracted from water molecules?
Unless there's a trick I don't know, NO. Water is 2 Hydrogen atoms and an Oxygen atom bound into a molecule. Lead is itself an element, not made up of Hydrogen, Oxygen, or any other elements.
What are the top three most known atoms?
The top three most known atoms are hydrogen, oxygen, and carbon. Hydrogen is the most abundant element in the universe, oxygen is essential for life as we know it, and carbon is the building block of all organic molecules.
Could life as we know it survive with only oxygen?
I think, no. We need oxygen and hydrogen to make water so with only oxygen and no hydrogen we would have no water and life as we know it cannot exist without water
Is The attraction between the hydrogen atom on one water molecule and the oxygen atom on another water molecule is an example of a hydrogen bond?
No! Oxygen atom in one molecule attracts two hydrogen atoms from two different molecules. This is because the oxygen atom is partially negatively charged, and hydrogen partially positively charged, and ther attract eachother. This interactions are called hydrogen bonds. One atom of oxygen attracts two atoms of hydrogens because it has two electron-pairs, so each electron-pair attracts one hydrogen atom. This is how it looks in water. http://upload.wikimedia.org/wikipedia/commons/f/f9/3D_model_hydrogen_bonds_in_water.jpg
How do you know that glucose is a compound?
Glucose is a compound made up of the elements carbon, oxygen and hydrogen. Glucose solution in water is a mixture of water molecules and glucose molecules. Mixing them doesn't produce any new substance, and you can separate them without creating any new molecules.
How is H2O formed?
H2O, or water, is formed when two hydrogen atoms share electrons with one oxygen atom through covalent bonds. The oxygen atom attracts the shared electrons more strongly, giving it a partial negative charge and the hydrogen atoms a partial positive charge, creating a polar molecule. This unique arrangement gives water its many special properties.
In one ton of water how much is hydrogen and how much is oxygen?
in a metric ton you wold have 1 Mega-gram of water. so the number of water moles would be the mass (1Ton) divided by the molar mass of water (18.06g/mol) and this will give 18016000 mol (1.802*10^7 mol) now multiply that by avogadro's constant 6.022*10^23 it will give 1.121*10^31 molecules of water, this means you have: 1120595200000000000000000000000 molecules of Oxygen and, double for hydrogen: 2241190400000000000000000000000 molecules.
