weight of oxygenweight of chlorine=(y)16.00(x)(35.45)=0.61230.3877 or y=3.5 x. Making this substitution in the formula for the molecular weight of the substance, we have 183.3=M=(x)35.45+(y)16.00 or 183.3=35.45+(16.00)(3.5)x=91.45∴x=(183.3)/(91.45)≈.2 With x=2 and y=...
Therefore measuring the amount of oxygen consumed allows determination of the amount of energy used. From a technical point, at least the minute ventilation (VE), and the gas fractions of oxygen (FEO2) and carbon dioxide (FECO2) have to be measured. In most cases also the heart rate, ...
The oxygen equivalent was used as a representative parameter of a mixture to follow, in particularly, its effect on the microstructure, toughness and crack propagation energy of the weld metal. For these investigated steels, the optimum gas mixture was established (5 % CO2, 0.91 % O2, balance...
Step 1: Determine the oxidation states of nitrogen in HNO₃ and NH₃. - In HNO₃ (Nitric acid), nitrogen (N) has an oxidation state of +5. - Calculation: - Hydrogen (H) = +1 - Oxygen (O) = -2 (there are 3 O atoms, so -2 × 3 = -6) - The overall charge of ...
4.EFFECT OF EQUIVALENCE RATIO ON THE COMBUSTION OF DIMETHYL ETHER/OXYGEN/ARGON FLAMES不同燃烧当量比对二甲醚燃烧的影响研究 5.Influence of Stoichiometric Ratio on De-NO_x by Reburning with Coal-Gas from Underground Gasification化学当量比对地下气化煤气再燃脱硝的影响 ...
The sodium cation attracts the negatively charged oxygen lone pair electrons of water via electrostatic interactions. Because of its small ionic radius of 1.02 Å, relatively tight solvation complexes are formed, composed mainly of triangular bipyramid, square pyramid, and square bipyramid43 as sc...
Cells are usually recharged at constant current at a rate which is limited by the need to control the cell temperature and ensure that oxygen produced at the positive towards the end of the charging cycle, or on overcharge, can diffuse to the negative. Various methods of charge control may ...
substitute, replacement - a person or thing that takes or can take the place of another 2. equivalent - the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen combining weight, eq, equivalent weight atomic mas...
As described above, the known low equivalent weight ionomers have a relatively high hydration. They are also known to be partially or completely soluble in water as well. These factors would counsel against their use in environments where water is produced, e.g. hydrogen-oxygen fuel cells, bec...
hydrogen-oxygen fuel cells, because these polymers tend to become physically unstable in these environments. In addition, as described above and shown recently (WO 00/52060, Table 1) the ionic conductivity decreases as the equivalent weight goes down concomitant with a large increase in hydration....
