mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,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 ...
单位是gmol^-1 MOLAR MASS就是指某ELEMENT的1 MOLE ATOM的质量 单位是gmol^-1 好啦 举点例子啦-V- 1 MOLE的SODIUM ATOM的RELATIVE ATOMIC MASS就是23.0 MOLAR MASS就是23.0gmol^-1... 1 MOLE的OXYGEN GAS的质量则用RELATIVE MOLECULAR MASS来表达 因为OXYGEN GAS是SIMPLE MOLECULAR STRUCTURE O...
aGiven the atom and mass ratios of X to oxygen, you need to figure out the mass of X that combines with 47.998 u O, i.e., the mass of three O atoms. At this point you divide by 2 and the result should appear some place in the periodic table! 假使X原子和大量比率氧气,您需要推测...

Rechargeable metal-air batteries are one of the most promising electrochemical energy storage devices due to their high energy density and low cost features [[1], [2], [3], [4], [5]]. Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are the key cathode processes for ...

As a side note, the radius of an atom is very ill-defined. Atoms themselves are fuzzy, and the distance between the nuclei depends on what nuclei, what bond, and pretty much everything. If one really can't avoid using an atomic radius, then he should check exactly what definition is ...
Only one oxygen atom in 21 was ionized before recombining in the mass spectrometer ion source. The rate constant for the reaction of O-atoms with N2O is less than 1 × 108 cm.3 mole1 sec.1, and several orders of magnitude less than this for the reaction O(3P) + N2O → 2NO. The...
