The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. These values correspond to the atomic weight divided by the usual valence; [2] for oxygen as example that is 16.0 g / 2 = 8.0 g. For acid–base reactions, the equivalent weight of an acid or ...
This invasion triggers the immune system to respond by sending white blood cells responsible for attacking microorganisms ( neutrophils) to the lungs. The neutrophils engulf and kill the offending organisms but also release cytokines that result in a general activation of the immune system. This results in the fever, chills, and fatigue common ...
The tonne (t) is an SI-compatible unit of mass equal to a megagram ( Mg ), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes. For example, a gigagram ( Gg) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .
