It is because aluminum cannot be recycled once corroded or used in reactions
Answer:
A
Explanation:
In a galvanic cell, energy is produced by spontaneous chemical processes.
The cathode and anode of this cell will depend on the relative position of the two metals in the electrochemical series.
Aluminium is higher in the electrochemical series so aluminium will be the anode. Silver is lower in the electrochemical series so silver will be the cathode.
Recall that oxidation (electron loss) occurs at the anode while reduction (electron gain) occurs at the cathode.
Find volume of pillow
L=78cm
B=55cm
H=25cm
Now
Mass=5.5kg
Density of water=1000kg/m^3
As it is less than density of water it will float on water
Answer:
Dot structures make it easy to count electrons and they show the number of electrons in each electron shell.
Arrow and line diagrams show the spin of electrons and show every orbital.
Written configurations require minimal space and show the distribution of electrons between subshells.
