Semiconductors are made of the metalloids silicon and germanium
On average, seawater in the world's oceans has a salinity of ~3.5%. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.
<h3>What is salinity ?</h3>
The saltiness or quantity of dissolved salt in a body of water is known as salinity (see also soil salinity). The standard units of measurement are grams of salt per liter (g/L) or grams per kilogram (g/kg; the latter is dimensionless and equal to ).
Salinity is a thermodynamic state variable that, along with temperature and pressure, controls physical properties like the density and heat capacity of the water. Salinity plays a significant role in determining many aspects of the chemistry of natural waters and of biological processes within them.
An isohaline, or isohale sometimes, is a contour line with a constant salinity.
The concept of salinity in rivers, lakes, and the ocean is straightforward, but it is difficult to define and measure properly on a scientific level.

Answer:
Explanation:
2Al(s) + 3 I₂(s) → 2 Al⁺³ + 6 I⁻
Aluminium is oxidised and iodine is reduced .
so cell potential = Ereduction - Eoxidation
Al⁺³ + 3e = Al - 1.66 V
I₂ + 2 e = 2 I⁻ 0.54 V
= .54 - ( - 1.66 )
= 1.66 + .54
= 2.2 V
