How do you make atomic hydrogen from molecular hydrogen?
(i) By thermal dissociationWhen molecular hydrogen is heated at 5000C,it dissociates into atomic hydrogen.(ii) By electric dischargeAt o.1 mm Hg to 1.00 mm Hg pressure
What are the forms of hydrogen?
There are three forms of Hydrogen (these are known as isotopes). These are normal hydrogen, deuterium and tritium.
What is the sum of the atomic masses of all the atoms in a molecule?
molecular mass
Effective atomic weight of water?
Atomic weights refer to ATOMS. Water is a MOLECULE made up of 3 atoms, it therefore does not have an atomic weight, it has a MOLECULAR weight.You calculate the molecular weight by adding up the atomic weight of all the atoms in the molecule.Waster is made up from 1 atom of Oxygen (atomic weight 16) and 2 atoms of Hydrogen (atomic weight 1)16+1+1 = 18The molecular weight of water is therefore 18.-------------------------------------------------------------------------------------The atomic mass of H is 1.008, and the atomic mass of O is 16.So 1.008*2+16=18.016
How can you construct the molecular orbital diagram for HF?
To construct the molecular orbital diagram for HF, you would first determine the atomic orbitals of hydrogen and fluorine. Then, you would combine these atomic orbitals to form molecular orbitals using the principles of quantum mechanics. The resulting diagram would show the energy levels and bonding interactions between the hydrogen and fluorine atoms in the HF molecule.
Can atomic hydrogen be formed by sodium hydride?
When hydrogen is liberated from a compound in a chemical reaction it invariably forms molecular hydrogen, H2, rather than atomic hydrogen.
How do you make atomic hydrogen from molecular hydrogen?
(i) By thermal dissociationWhen molecular hydrogen is heated at 5000C,it dissociates into atomic hydrogen.(ii) By electric dischargeAt o.1 mm Hg to 1.00 mm Hg pressure
Calculate the molecular mass of hydrogen bromine?
The atomic mass of hydrogen is 1u. Atomic mass of bromine is 80u. Therefore, the molar mass of hydrogen bromide is 1+80=81u.
Hydrogen or carbon dioxide is smaller?
Hydrogen has by far the smaller molecular mass (and atomic number) making it the smallest element
What are the forms of hydrogen?
There are three forms of Hydrogen (these are known as isotopes). These are normal hydrogen, deuterium and tritium.
A molecule of water is composed of two atoms of hydrogen and one atom of oxygen if the atomic mass number of hydrogen is 1 and the molecular mass of water is 18 the atomic mass of oxygen must be?
The molecular mass of water (H2O) is 18, which means the total mass of one oxygen atom and two hydrogen atoms is 18. Since the atomic mass number of hydrogen is 1, the atomic mass of oxygen can be calculated as 16 (18 - 2).
What is the relative mass formula of hydrogen gas?
The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.
What are the gram molecular weights ofC6H8O7?
gram molecular weight of C6H8O7=(atomic weigth of carbon X 6)+(atomic weigth of hydrogen X 8+(atomic weigth of oxygen X 7) grams
What is the molecular mass of hydrogen?
For H2 (natural occurring element Hydrogen) it is 2*1.00794 a.m.u = 2.01588 a.m.eThis means that 1.00000 mole H2 has a mass of 2.01588 grams
What is the sum of the atomic masses of all the atoms in a molecule?
molecular mass
What is the Difference between nascent and molecular hydrogen?
Scientifically, nascent refers to a substance at the point at which it forms. In a chemical reaction, such as zinc reacting with sulphuric acid, individual hydrogen atoms will form but VERY quickly react with another atom to give H2 molecules. This is the only common situation in which atomic hydrogen exists, even if very fleetingly.
What is the atomic mass of a Hydrogen and oxygen atom?
If the atomic mass of water is 18 and the atomic mass of hydrogen is 1 then the atomic mass of oxygen is 16
