Both minerals are hydrated magnesium silicates, and are similar but not identical in terms of chemical composition.

Both are used to measure the energy required to change the vibrational state of a chemical compound.

Both effective temperature and bolometric luminosity actually depend on the chemical composition of a star.

Both of these share similar physical characteristics ( Resistance to biological and chemical weapons, highly efficient metabolisms, armored body structures etc.

Both sulfurization / desulfurization techniques and the use of removable thiol auxiliaries involve the installation of a synthetic thiol moiety to carry out the standard native chemical ligation chemistry, followed by removal of the auxiliary / thiol.

Both lower the kinetic barrier and speed up the attainment of chemical equilibrium.

Both the Bhopal and the Institute incidents underscored the reality of modern-day chemical production — no matter what safety precautions are taken, no matter how well trained a plant's employees may be, and no matter how prepared a plant may be to handle an emergency situation, accidents will occur and people will die.

Both pH and redox potentials are properties of solutions, not of elements or chemical compounds per se, and depend on concentrations, temperature etc.
