RMO = Ratio of the # of moles of oxygen to # of moles of oxidizable compound in their reaction to CO 2, water, and ammonia. For example, if a sample has 500 Wppm (Weight Parts per Million) of phenol: C 6 H 5 OH + 7O 2 → 6CO 2 + 3H 2 O COD = (500/94)·7·16*2 = 1192 Wppm
The eco-costs of a product are the sum of all eco-costs of emissions and use of resources during the life cycle "from cradle to cradle". The widely accepted method to make such a calculation is called life cycle assessment (LCA), which is basically a mass and energy balance, defined in the ISO 14040, and the ISO 14044 (for the building industry ...
The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
[11] [12] During combustion, sodium sulfate is reduced to sodium sulfide by the organic carbon in the mixture: 1. Na 2 SO 4 + 2 C → Na 2 S + 2 CO 2. This reaction is similar to thermochemical sulfate reduction in geochemistry. The molten salts ("smelt") from the recovery boiler are dissolved in a process water known as "weak wash".
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
The wet sulfuric acid process (WSA process) is a gas desulfurization process. After Danish company Haldor Topsoe introduced this technology in 1987, it has been recognized as a process for recovering sulfur from various process gases in the form of commercial quality sulfuric acid (H 2 SO 4) with the simultaneous production of high-pressure steam.

Carbon pricing (or CO 2 pricing) is a method for governments to mitigate climate change, in which a monetary cost is applied to greenhouse gas emissions. This is done to encourage polluters to reduce fossil fuel combustion, the main driver of climate change .
