What type of reaction is shown below?

fe (s) + cu(no3)2 (aq) → fe(no3)2 (aq) + cu (s)

select one:
a. synthesis
b. single displacement
c. double displacement
d. decomposition

The correct answer is :

b. Single displacement reaction

Explanation:

The single displacement reaction is the one in which the more reactive element substitute other element in a compound generating a new chemical compound.

It follows this kind of reactions :

Now look at the reaction given;

Here the more reactive element (Fe) displaces the less reactive element [Cu]from the compound[Cu(NO3)2].

Hence Fe substitute Cu from Cu(NO3)2 and form Fe(NO3)2

It is not a double - displacement reaction . Where the elements interchange themselves to form the compound.

hi my dude or dudette

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
