Found in different ores Fe 2(magnetite) and Fe 3 (haematite)
They have different valencies (+2 and +3)
They form different coloured compounds Fe 2 is green while Fe 3 is rust-brown.
the numbers 2 & 3
Iron II nitrate contains an iron ion with a 2+ charge and has the formula Fe(NO3)2. Iron III nitrate contains an iron ion with a 3+ charge and has the formula Fe(NO3)3
It's basically a difference in the electron shell arrangement of the central Iron atom. In Iron II Nitrate, Iron has a +2 charge (Fe2+) and in Iron III Nitrate, Iron has a +3 charge (Fe3+). So there are two nitrates attached to Iron II: Fe(NO3)2 and three nitrates attached to Iron III: Fe(NO3)3.They would both behave nearly identical in solutions since nitrates dissociate 100% but the Fe2+ and Fe3+ ions are useful in voltaic cells.
FeO is iron II oxide or ferrous oxide. In this compound iron forms a 2+ ion which combines with oxygen(which forms a 2- ion) in a 1:1 ratio Fe2O3 is iron III oxide or ferric oxide. In this compound iron forms a 3+ ion which combine with oxygen (again a 2- ion) in a 2:3 ratio. In Fe2O3 iron is in its highest oxidation state. FeO is black, Fe2O3 is red. Fe2O3 is more common. FeO is a better conductor than Fe2O3.
Iron 2 is Fe 2+ and has electron configuration [Ar] s1d5 Iron 3 is Fe 3+ and has electron configuration [Ar] d5
the numbers 2 & 3
Ferrous ion carries a +2 charge and Ferric carries + 3
Iron II nitrate contains an iron ion with a 2+ charge and has the formula Fe(NO3)2. Iron III nitrate contains an iron ion with a 3+ charge and has the formula Fe(NO3)3
What is the difference between 2-pentanol from 3-pentanol?
It's basically a difference in the electron shell arrangement of the central Iron atom. In Iron II Nitrate, Iron has a +2 charge (Fe2+) and in Iron III Nitrate, Iron has a +3 charge (Fe3+). So there are two nitrates attached to Iron II: Fe(NO3)2 and three nitrates attached to Iron III: Fe(NO3)3.They would both behave nearly identical in solutions since nitrates dissociate 100% but the Fe2+ and Fe3+ ions are useful in voltaic cells.
1. The difference of two numbers are the numbers between them. The difference is found by subtracting the smaller number from the larger. In this case, 2 is subtracted from 3 (3-2) with a difference of 1. 3-2=1
The difference is 3 1/4.
2 - 5 = -3 5 - 2 = 3
Difference is a subtraction word. What is the difference between 5 and 2 = 3
5 + 3 =8 and 5-3 = 2 The difference between the two numbers is 2.
The difference is 2 and 7 eighths.
You would ahve to figure out the number.....For example: if the number was 3....3-2=1...that is the difference between 2 and 3
