Summary
| Description |
English: Catalytic oxidation of ammonia
A fine powder of chromium(III) oxide heated to red-hot, is added (immediately after being heated) to a flask filled with a mixture of gaseous ammonia and air. When inserted, around the chromium(III) oxide particles (a catalyst), oxidation takes place. This oxidation can be described by the chemical equations (other chemical equations could also be written, giving NO and/or NO2): 4NH3(g) + 3O2(g) = 2N2(g) + 6H2O(g) 2NH3(g) + 2O2(g) = N2O(g) + 3H2O(g) Performed by the Prof. PhD Miha Bukleski. The planning of the experiment also included the retired Prof. PhD Vladimir Petruševski and the students Mihail Trajkov and Darko Stojčev, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.Македонски: Каталитичка оксидација на амонијак
Во колба исполнета со гасовит амонијак, се додава ситно спрашен хром(III) оксид кој непосредно пред тоа е загреан до зажарување. По неговото внесување во колбата, околу ситните честички на хром(III) оксидот кој игра улога на катализатор, започнува оксидација на амонијакот, која може да се претстави со хемиските равенки (можно е да се напишат и други равенки, со други производи– NO и/или NO2): 4NH3(g) + 3O2(g) = 2N2(g) + 6H2O(g) 2NH3(g) + 2O2(g) = N2O(g) + 3H2O(g) Изведено од Проф. д-р Миха Буклески. Во планирањето на опитот, исто така беа вклучени пензионираниот Проф. д-р Владимир Петрушевски, и студентите Михаил Трајков и Дарко Стојчев, Институт за хемија, ПМФ, УКИМ, Скопје, Македонија. |
