Which type of chemical reaction does this word equation exemplify: iron metal plus copper (II) sulfate solution yields iron (II)
2 answers:
Answer: Single replacement
Explanation:
Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
Iron being more reactive than copper would displace copper from its salt solution and thus will generate copper and iron sulphate.
The chemical equation representing iron metal plus copper (II) sulfate solution yields iron (II) sulfate solution and copper metal is:

Explanation:
Expression for the kinetic energy is as follows.
K.E =
Now, total kinetic energy will be as follows.
K.E = =
Since, this energy converts into electromagnetic radiation of wavelength 121.6 nm.
Relation between energy and photon is as follows.
Energy of photon =
=
=
v =
= m/s
Thus, we can conclude that atoms were moving at a speed of m/s before the collision.
