How is the mole of a hydrogen the same asa mole of helium?
1 mole of all elements has 6.023 x 1023 atoms (but one mole of each element will weigh different)
How many moles of hydrogen gas could be produced by the complete decomposition of 1 mole of water?
Since a water molecule, H2O, has exactly the same quantity of hydrogen atoms as a hydrogen molecule, H2, it follows that one mole of water can be decomposed into one mole of hydrogen gas.
Does iron weigh the same as iron oxide?
The right question should be: Does one mole of iron weigh the same as one mole of iron oxide? The answer is NO, Iron Oxide weighs more.
What weighs more hydrogen atoms or carbon atoms?
Carbon atoms would weigh more because they have six protons and six neutrons. The most common form of Hydrogen has one proton and no neutrons, which means that Carbon is normally about 12 times as heavy as Hydrogen (in their most common forms).
Mole of hydrogen vs mole of uranium?
A mole of hydrogen contains Avogadro's number of hydrogen atoms, while a mole of uranium contains Avogadro's number of uranium atoms. Hydrogen is a light element with a low atomic weight, while uranium is a heavy element with a high atomic weight. This means that a mole of hydrogen weighs much less than a mole of uranium.
What is the relationship between a mole of oxygen and a mole of hydrogen in terms of their respective quantities and atomic composition?
A mole of oxygen and a mole of hydrogen have the same quantity of particles, which is approximately 6.022 x 1023 atoms or molecules. However, they differ in their atomic composition, with oxygen having 16 times the atomic mass of hydrogen.
True or false a mole of water in chemistry contains the same number of atoms as a mole of methane?
False, They contain the same number of molecules, not the same number of atoms. H2O contains 3 atoms, so in 1 mole of water there are 6.022*10^23 * 3 = 1.81*10^24 atoms. CH4 contains 5 atoms, so in 1 mole of methane there are 6.022*10^23 * 5 =3.01*10^24 atoms.
Is a Water Shrew in the same family as a mole?
no
Which term is same for one mole of oxygen and water?
The number of particals (molecules, atoms, ions etc.) in one mole of ANY substance is the same: 6.022*1023 (Avogadro's number)
Does a mole of water weigh less than a mole of sugar?
A mol is a mol is a mol - no. A mol is a standard unit of measurement and thus any substance, when designated a "mol" will have the same number of particles. Therefore, a mol of salt would have the same number of particles as a mol of sugar. It is like asking if a pound of feathers would weigh more or less than a pound of steel.
How can you tell there is more oxygen in hydrogen peroxide than in water?
You can tell that there is more oxygen in hydrogen peroxide than in water because hydrogen peroxide has an extra oxygen atom compared to water. The chemical formula for hydrogen peroxide is H2O2, while the formula for water is H2O. This extra oxygen in hydrogen peroxide makes it a more oxidizing chemical compared to water.
If two things weigh the same in water do they weigh the same in air too?
they would weigh the same everywhere
