While an account of the physical basis of mind must explain many things, this appears to be the most difficult. It is impossible to exclude the phenomenological features of experience from a reduction in the same way that one excludes the phenomenal features of an ordinary substance from a phys...

At 25.8°C water has a vapor pressure of 24.912 torr. What is the mole fraction of water vapor at 25.8°C if Patm is exactly 1 atm? Dalton's Law of Partial Pressures: According to Dalton's law of partial pressures, the total pressure o...
, petroleum processing, glass and ceramic manufacturing, metal refining and fabrication processes, pulp and paper manufacturing, and healthcare industries. In addition to its chemical name N2, nitrogen is also referred to as GAN or GN in the gaseous state and LIN or LN in the liquid state....
Hydrogen is the simplest chemical element, or type of atom. It consists of just one proton and one electron. It is also the most abundant element, making up around 75% of the known matter in the universe. Vast amounts of hydrogen exist in water and living things. ...
complexified by environmental mechanisms. While this review is by no means exhaustive, many of the issues central to the state of the art of prebiotic chemistry are reviewed here. Introduction “Prebiotic chemistry” can be understood to mean various things: chemistry which occurred before life ...
We then introduce realizability of RNs by sum formulas and structural formulas as a first step towards a formalization of chemistry-like networks, and show that conservation of matter is already sufficient to guaran- tee the existence of such chemistry-like representations. Finally we discuss the ...
