Answer:
Explanation:
The valency of aluminium is +3 while the valency of chlorine is -1
we will first write the half reactions
Half oxidation reaction
Now will write the complete equation-
The balanced equation would be
A voltaic cell spontaneously converts chemical energy to electrical energy. The correct option among all the options given in the question is option "2".
Actually voltaic cell is an electrochemical cell that
converts the chemical contained within it by the process of chemical reaction
to produce electrical energy. The voltaic cell contains an anode and a cathode.
Anode is an electrode where the oxidation occurs and cathode is the electrode
where reduction occurs. The oxidation and the reduction part occurs in two
separate parts of the cell known as half-cell.
Answer:
Explanation: n=m/M(molar mass)
n=24.3 grams/(16+2x1.008)grams/moles(molar mass of H2O)
n=24.3grams/18.016grams/moles
n=1.35moles
Viscosity refers to a fuilds resistance to flow.
EX: Honey have higher viscosity than water.
Explanation:
the energy that that is needed to break a bond is called the bond energy or dissciation energy
