Triatomic gases: Molecules of these gases have three atoms and are called triatomic having atomicity equal to three. Some common example of triatomic gases is carbon dioxide, water vapour, nitrous oxide, ozone etc.
Q. Why Oxygen is a diatomic element?
Answer. Oxygen is a diatomic element because it consists of two atoms of same element O and O that makes O2.
Q. What is CV for a monatomic gas?
The molar specific heat capacity of a gas at constant volume Cv is the amount of heat required to raise the temperature of 1 mol of the gas by 1◦C at the constant volume. Its value for monatomic ideal gas is 3R/2 and the value for diatomic ideal gas is 5R/2.
Q. Which one is a triatomic molecule?
Introduction. Triatomic molecules are molecules that contain three atoms. The atoms in triatomic molecules can all be the same, as in I3-, all be different, as in HCN, or can be a mix like CO2. Examples include H2O, which is a bent and has a bond angle of 109o, and a linear triatomic molecule such as CO2.
Q. Why the shape of CO2 is linear but water is bent?
In water molecule there are two lone pairs of electrons connected to the oxygen, hence the lone pairs push the hydrogen atoms, creating a bent shape. in CO2, however, there are two double bonds and no lone electrons on the central atom, hence the molecule has a linear shape.
Q. Is CaCl2 Triatomic?
Tri-atomic molecules are CaCl2, H20. Tetra-atomic molecules are NH3, PCL3.
Q. Is CH3Cl Tri-Atomic?
Answer. Tri-atomic —.> CH3Cl is poly-atomic that is more than 4.
Q. What is the difference between triatomic and tetra atomic?
Triatomic means there are 3 atoms in the molecule of that substance. Tetra atomic means there are 4 atoms in the molecule of that substance.
Q. Which of the following is Triatomic?
Carbon dioxide is a triatomic molecule. Triatomic molecules are the molecules which comprised of three atoms, which are either the identical or different chemical elements.
