Semiconductors are made of the metalloids silicon and germanium
Iron (II) iodide solution will contain the highest concentration of iodide ions. Option D is the right answer.
Explanation:
Reference table F is used to check the solubility of the metal compounds formed. It tells if the compound is soluble or insoluble in water.
From the table, it is seen that Mercury, silver and lead form insoluble complex with iodide ions. This means that they have low concentration of dissolved iodide ions. These three metals lead, silver and mercury are given as exception in the table F.
Thus iron(II) iodide will have highest concentration of iodide ions when dissolved in water.
Answer:
a) increases.
b) remains the same.
c) decreases. the hydrogen molecules constrict or shrink from actual size!
Explanation:
Since ,
Density is given as mass divided by the volume .
( a ) As the Chlorine gas is compressed , the molecules of gas comes close to each other , and hence , the density increases .
( b ) When the lead is taken to high mountain , its density remains the same , as density is independent of higher pressure , as going to mountain will increase the pressure .
( c ) As the water is freeze , its density decreases ,
Because ice is less dense than water , as seen , the ice ice can float on the surface of water .
Answer: It may swell.
Explanation: Bacteria or mold will grow in it giving off gasses that are harmful to ingest. The swelling may cause the gas to burst or mold.
