Ca40 20 !2O16 8 þ4H1 1 þ4 neutrons ð5:4Þ From reaction (5.3), we can consider a decrease in Ca concentration of 1.6 % and the formation of 1.0 % of Mg and 0.6 % of O. On the other hand, from reaction (5.4), we obtain a decrease in Ca equal to 5.9 %. This decrease gives an increase of 4.7 % in O and 0.6 in H, with neutron emissions equal to 0.6 %. Considering the O increases coming from reactions (5.2), (5.3), and (5.4), totally equal to 18.2 %, and the experimental evidence reporting a total measured O concentration of 18.5 %, we may assume that O seems to be almost perfectly justified by the proposed reactions. At the same time, the Mg increment observed after the experiment can be explained by the results of reaction (5.3), see also Table 5.1. According to reactions (5.3) and (5.4), the following balances may be considered: Ca ( 1.6 %) ¼Mg (+1.0 %) + O (+0.6 %); Ca ( 5.9 %) ¼O (+4.7 %) + H (+0.6 %) + neutrons (+0.6 %). Taking into account the same reactions, and considering the Ca increase coming from reaction (5.1) (10.8 %), a concentration of 3.3 % of Ca remains to be counterbalanced. To this purpose, it is possible to take into account additional reactions involving Ca as starting element and Si, K and C as the results: Ca40 20 !K39 19 þH1 1, ð5:5Þ Ca40 20 !C 12 6 þSi 28 14: ð5:6Þ Fig. 5.5 Traces of Ca concentrations have been detected after the electrolysis Fig. 5.6 The presence of the oxygen is remarkable after the experiments 42 A.
