Answer: 1 mol of
will be produced from this reaction.
Explanation: Reaction follows,

As seen from the balanced chemical equation above, we get
For every 3 moles of Aluminium and 3 moles of
, 1 mole of
is formed.
For every 3 moles of Aluminium and 3 moles of
, 1 mole of
is formed.
For every 3 moles of Aluminium and 3 moles of
, 3 moles of
is formed.
For every 3 moles of Aluminium and 3 moles of
, 6 moles of
is formed.
Answer:

Explanation:
A galvanic cell is composed of two electrodes immersed in a suitable electrolyte and connected via a salt bridge. One of the electrodes serves as a cathode where reduction or gain of electrons takes place. The other half cell functions as an anode where oxidation or loss of electrons occurs.
The representation is given by writing the anode on left hand side followed by its ion with its molar concentration. It is followed by a salt bridge. Then the cathodic ion with its molar concentration is written and then the cathode.
As it is given that cadmium acts as anode, it must be on the left hand side and copper must be on right hand side.

The correct answer is
Energy of electrons depends on light’s frequency, not intensity.
As per photoelectric effect, if we incident a light on metal surface it will results into emission of electron from it
if we increase the number of photons the number of electrons will increase however if we increase the frequency the number of photons will not increase
While if we increase frequency the energy of electrons will increase as
Energy of photon = Work function of metal + kinetic energy of electrons
