Question

which block in the periodic table contains the metalloids?
a) d block
b) s block
c) f block
d) p block
question 4 (5 points)
which type of chemical process is used to remove salt from ocean water?
a) desalination
b) alkylation
c) doping

Explanation:

• For the first question: Metalloids are located in the \(p\) block of the periodic table. The \(s\) block contains metals (alkali and alkaline - earth metals). The \(d\) block contains transition metals. The \(f\) block contains inner - transition metals (lanthanides and actinides).
• For the second question: Desalination is the process used to remove salt from ocean water. Alkylation is a reaction in organic chemistry where an alkyl group is added to a molecule. Doping is a process in semiconductor manufacturing where impurities are added to a semiconductor.

Answer:

D. \(p\) block
A. Desalination
