Boron reacts with halogens to give the corresponding trihalides. Boron trichloride is, however, produced industrially by direct chlorination of boron oxide and carbon at 500 °C. B2O3 + 3C + 3Cl2 → 2BCl3 + 3CO The carbothermic reaction is analogous to the Kroll process for the conversion of titan...
There is an extra note; Azar also gives an interesting part in the article that both influences on certain traits "change as people age". Basically, two persons are not going to react on an experience the same way since they have different chemistry in each individual. ...
