Answer:
1
Explanation:
Oxygen is a pure substance therefore it is only made up of one kind of atom
Mass of the shells will remain constant.
Explanation:
Sedimentary rocks are formed by the rocks that have been weathered. The microscopic shells, small pieces of rocks and mineral particles get deposited on this weathered sedimentary rocks.
The texture or chemical properties of the microscopic shell get changed. but the amount of microscopic shell deposited to make sedimentary rocks remains the same.
Chalk and coral reefs are the example of sedimentary rocks made up with microscopic shells.
The skeletal part of the shells takes part in rock formation whose mass remains unchanged although physical and chemical properties go changes.
It is predicted to lie at a wavelength of 91.2 nm.
Rydberg equation is a mathematical formula that is used to predicts the wavelength of light resulting from an electron moving between energy levels of an atom. Rydbery equation is used to describe the spectral wavelengths of chemical elements. The equation is made up of different components, which include n1 and n2. The n1 of the equation has a value of 1 while the n2 runs from 2 to infinity; this makes the spectral lines to converge at point 91.2 nm.
