n+o2=no2
valency of nitrogen in nitrogen dioxide(NO2) is 2
The molecular geometry of NO2 is linear. N(triple bond)N(single bond)O
N is +3, O is -2. The anion has an oxidation number of -1 (equal to its charge)
Determine the molar mass of NO2 using the subscripts in the formula and the atomic weights in grams from the periodic table. 1 mole NO2 = (1 x 14.0067g N) + (2 x 15.9994g O) = 46.0055g NO2 Calculate the moles NO2 by dividing the given mass by the molar mass. 25.5g NO2 x (1mol NO2/46.0055g NO2) = 0.554mol NO2
N+O = No2
-2 for each O, +4 for N
N + o2 => no2 s + o2 => so2
N= 7 O = 16 Molar mass = 39
if you mean NO2, then 1 Nitrogen, 2 Oxygen. It is a toxic brown gas called nitrogen dioxide. if you mean No2, then no such substance exists. No is the element called nobelium. Since it is a metal it does not form molecules.
The product is nitrogen dioxide.
Nitrogen has plus 4 oxidation state.Oxygen has minus two.
