Knallgas (Ger). An exptl mixt of H2 and 02, or air. The effect of initial mixt density on the initiation of detonation in knallgas and the detonation properties of heavy knallgas (2D2+02) have been studied... 

Initial mixt composition ranges of knallgas and w vapor in a detonation tube were varied by controlling temps at 100, 200 300°, for knallgas densities of 0.64-1.8, 8.5—16 46-62g/liter, respectively. Ignition was by hot wire. The threshold composition decreased as initial mixt density increased. Threshold compositions were 62, 44 V36% knallgas at 100, 200 300°, or initial mixt densities... 

Such inorganically released hydrogen would have been available to be exploited by microbial life. Some archaea and bacteria use the knallgas reaction ... 

Now the affinity A of the reaction 2H2 + 02 -> 2H20, in which the reactants are gaseous and the resultant a liquid, e the affinity of the actual process occurring in the Knallgas cell, is given by—... 

This can be calculated numencally from equation (9c) given above We can thus calculate the affinity of the reaction m the Knallgas cell Now A refers to the formation of 2 moles of water To foim 2 moles of water electncally requires four faradays, and hence A = 4E, where E is the electromotive force of the cell Calculating Kp as above...

In certain aerobic organisms, such as hydrogenomonas, H2 and O2 are caused to react (but not directly) according to the Knallgas reaction ... 

The electron transfer in redox processes is often accompanied by a transfer of protons, H+. The simplest example is the oxidation of H with by the so-called Knallgas-bacteria , which occur widespread in aquatic sediments ... 

The aerobic hydrogen bacteria, generally known as Knallgas-bacteria", are not phototrophic and are very easy to grow. The formation of cell material from hydrogen, oxygen, and carbon dioxide can be summarized by the following equation ...
