What is "chemical compositions"

Usage examples of "chemical compositions".

And so he worked on, trying to incorporate into the calculation skylight radiance intensities, Chandrasekhar's radiative transfer equation, chromaticity scales, aerosol chemical compositions, Le-gendre polynomials to evaluate the angular scattering intensities, Riccati-Bessel functions to evaluate the scattering cross sections, and so on-occupying the better part of the drive to Arena Glacier, concentrating hard and steadfastly ignoring the world around him and the situation in which he now found himself.

Men are too slow to analyze quickly all the material the robot will send back-- temperatures and gas pressures and cosmic-- ray fluxes and Solar-wind intensities and chemical compositions and soil textures and easily three dozen more items-- and then try to decide on the next step.

Though the waxy substances listed above all have different chemical compositions, they are all carbon-based, composed primarily of chemical compounds made up of carbon and hydrogen and oxygen.

In one room was his pride and joy, a mass spectrometer for determining chemical compositions and molecular weights.

There would surely be some exotic chemical compositions and reactions involved.
