Balance the following skeleton reactions and identify the oxidizing and reducing agents:(b) CrO₄²⁻(aq) + Cu(s) → CrOH₃(s) + CuOH
andrew-mc [135]

The balanced skeleton reactions are given below

2CrO₄²⁻(aq) + 3Cu(s)  +8H_{2} O(l) → 2Cr(OH)₃(s) + 3Cu(OH)₂(s) + 6OH^{-}(aq)

The oxidising agent and  reducing agents are Cr and  Cu .

There are following steps involve in balance redox reaction in basic medium .

  • First divide the reaction into two half reactions which give oxidation and reduction half reaction.
  • Then balance the elements other than oxygen and hydrogen atom.
  • Balance the oxygen atom by adding H_{2} O where number of oxygen is less .
  • Balance the hydrogen atom by adding H^{+} on another side of where water molecule added.
  • Add OH^{-} ions to both sides to neutralize  H^{+} ion.
  • Combine  H^{+} and OH^{-} ion to make H_{2} O .
  • Balance the charge by adding e^{-} .
  • Add the half reaction  .

The species which reduces the other species in the redox reaction is called oxidizing agent . Similarly , the species which oxidize the other species in the redox reaction  is called reducing agent .

What is the energy of a TV wave that NBC broadcasts, if it has a wavelength of 32 meters?
serg [7]

Answer:

Explanation:

E = hc/λ

h = planck's constant = 6.66 x 10 ^ -34

c = speed of light = 2.98 *10^8 m/s

E = (6.66 x 10 ^ -34 )(2.98 *10^8)/32

  = 19.85 * 10 ^-26

   =0.62 x 10^-26

   = 6.2 x 10^-27 J
