Possible Chemical Reaction
How many possible chemical reactions are there among these reactions?
-
F e O + 2 H N O 3 → F e ( N O 3 ) 2 + H 2 O
-
F e ( O H ) 2 + 2 H N O 3 → F e ( N O 3 ) 2 + 2 H 2 O
-
3 F e ( N O 3 ) 2 + 4 H N O 3 → 3 F e ( N O 3 ) 3 + N O + 2 H 2 O
-
F e 2 O 3 + 6 H N O 3 → 2 F e ( N O 3 ) 3 + 3 H 2 O
Type your answer.
The answer is 2.

3 solutions
ty. you post interesting problems. it would be nice to know why the two reactions will not happen and why the other 2 do happen.
the sum of the elements fits for all 4 "equations", so some wording would be nice.
like: FeO does not ...
No. of tries = 3
No. of options = 5
Probability of getting correct = No. of options No. of tries = 5 3 = 6 0 %
Oops, thanks for your notice!

BTW, which ones are correct. I really don't know.
Lol. Actually it's 5 3 = 6 0 % as 0 is also a possible answer. :)
there can be only four answers and there are 3 chances .........
The last 2 chemical reactions are possible to happen.
Correcting the first 2 reactions:
3 F e ( O H ) 2 + 1 0 H N O 3 → 3 F e ( N O 3 ) 3 + N O + 8 H 2 O (Concentrated nitric acid)
F e O + 4 H N O 3 → F e ( N O 3 ) 3 + N O 2 + 2 H 2 O (Concentrated nitric acid)
3 F e O + 1 0 H N O 3 → 3 F e ( N O 3 ) 3 + N O + 5 H 2 O (Dilute nitric acid)
