What is the valency of nitrate anion?
The formula for the nitrate ion is NO3- so the valency is -1.
How many moles of molecules are in 25.5g of NO2?
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
How does oxides of nitrogen come into the atmosphere?
N+O = No2
What are the Oxides of Nitrogen and Sulfur?
N + o2 => no2 s + o2 => so2
Molar mass of no2?
N= 7 O = 16 Molar mass = 39
What is the valency of nitrate anion?
The formula for the nitrate ion is NO3- so the valency is -1.
What is the product of N plus O2 equals NO2?
n+o2=no2
What does the n mean in no2?
nitrogen
What is the molecular geometry of NO2?
The molecular geometry of NO2 is linear. N(triple bond)N(single bond)O
What non-metals has no variable valency Zn Cu Fe N?
Zinc (Zn) does not have variable valency
What is the oxidation number for NO2?
N is +3, O is -2. The anion has an oxidation number of -1 (equal to its charge)

Symbol valancy for nitride?
Symbol of nitride is N and its valency is 3
What is the oxidation number in NO2?
-2 for each O, +4 for N
Formula of barium nitride?
Barium is in group 2, so has a valency of 2. Nitrogen is is in group 15, so has a valency of 3. You have to get the total valencies to equal so: Ba3N2. Total valency of Ba=3x2=6. Total valency of N=2x3=6.
