If we have 5g of C 2 H 6, how many moles of C 2 H 6 do we have? Oxidizing agent is Cr(NO 3) 2. See Answer. Similarly, in the reaction of mercury(II) with nitrite ion to give mercury metal and nitrate ion, the oxidation number of mercury is initially 2, but it changes to zero, so mercury is reduced. Our videos prepare you to succeed in your college classes. Reducing agent/reductant-species oxidised. Identify the reducing agent in the following reactions (a) 4NH 3 + 5O 2 →4NO + 6H 2 O (b) H 2 O + F 2 → HF + HOF (c) Fe 2 O 3 + 3CO → 2Fe + 3CO 2 (d) 2H 2 + O 2 →2H 2 O The equation 4NH3 + 5O2 → 4NO + 6H2O, represents the catalytic oxidation of ammonia. Some common reducing agents include metals such as Na, Fe, Zn, Al and non-metals such as C, S, H 2. B) oxygen becomes reduced. Want to see the step-by-step answer?
