Saint John Bosco: Overcoming All Kinds of Obstacles. The great Saint John Bosco has an eminently priestly expression, but that of a man of the people. He was a peasant who became a priest, and that was a glory to him. There is something truly majestic in him.
Chromium trioxide is the inorganic compound with the formula CrO 3. It is the acidic anhydride of chromic acid, and is sometimes marketed under the same name. This compound is a dark-purple solid under anhydrous conditions, bright orange when wet and which dissolves in water concomitant with hydrolysis.he trioxide reacts with cadmium, zinc, and other metals to generate passivating chromate films that resist corrosion. It is also used in the production of synthetic rubies. Chromic acid solution is also used in applying types of anodic coating to aluminium, which are primarily used in aerospace applications.
R-CH3 is an organic composite obtained starting from methane (CH4) and substituting one of the hydrogen atoms with an organic radical, generally indicated with R. Frequently t â¦ he functional group-CH3 is also called methil group.mportant examples are acetic acid, where R is the acid group COOH, so that the acetic acid has molecular formula CH3COOH and the methanamine, where the functional group is the amine group (NH2) so that the molecular formula results to be CH3NH2. 1 person found this useful.
