Answer:
1. Iron(iii) hydroxide
2. It is a base
Explanation:
To determine the name of the compound, we must find the oxidation number Fe in the compound since the oxidation number of O is —2 in all its compound except for peroxide where it —1 and the oxidation number of Hydrogen is always +1 in all its compounds except for hydrides where it is —1. The oxidation number of Fe can calculated as follows:
Fe(OH)3 = 0
O = —2
H = +1
Fe =?
Fe + 3( —2 + 1) = 0
Fe + 3(—1) = 0
Fe —3 = 0
Fe = 3
The oxidation number of Fe in Fe(OH)3 is 3.
Therefore, the name of Fe(OH)3 is Iron(iii) hydroxide
Fe(OH)3 is a base since it contains the OH group
<h2>The net ionic equation that correspond to Fe(ClO4)2 +Na2CO3 is</h2>
<u>Fe ^2+(aq) +CO3^2-(aq) → FeCO3 (s)</u>
<h3>Explanation</h3><h3 /><h3>write the balance chemical equation</h3>
Fe(ClO4)2 (aq) + Na2CO3(aq)→ FeCO3 (s) + 2 NaClO4
<h3>write the ionic equation</h3>
Fe^2+(aq) + 2ClO4 ^-(aq) + 2Na^+(aq) +CO3^2- (aq) → FeCO3 (s) + 2Na^+ + 2ClO4^-
<h3>cancel the spectator ions in both side</h3>
- that is ( 2ClO4^- and 2Na+)
the ionic equation is therefore
<u>Fe^2+(aq) + CO3^2- →FeCo3(s)</u>
Answer:
2Na (s) + Cl2 (g) -->2NaCl (s) + heat
Explanation:
In computing, input/output or I/O (or, informally, io or IO) is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system.
Hope this helped!
Good luck :p
