What is the differance between iron ii nitrate and iron iii nitrate?

The difference between iron (II) nitrate and iron (III) nitrate: difference in oxidation states of iron in both compounds.

Explanation:

1) Iron(II) nitrate :

In iron(II) nitrate , iron is present in the +2 oxidation state.The molecular formula is given as:

= ferrous nitarte

2) Iron (III) nitrate

In iron(II) nitrate , iron is present in the +3 oxidation state.The molecular formula is given as:

= Ferric nitrate

i need to show me the graph so i can give u an answer

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
