(a) Laboratory bottles to contain relatively dilute solutions of nitric acid (b) Barrels to contain benzene (c) Pipe to transport hot alkaline (basic) solutions (d) Underground tanks to store large quantities of high-purity water (e) Architectural trim for high-rise building

Sagot :

Answer:

a) polytetrafluorethylene

b) polyethylene terepthalate

c) Nickel

d) Polytetrafluroethylene

e) Aluminum

Explanation:

a) polytetrafluorethylene can be used to make laboratory bottles that can contain nitric acids ( dilute ones ) because of its resistance to either acidic or basic solution

b) polyethylene terepthalate can be used because it is relatively cheaper, also Benzene doesn't exhibit corrosion effect

c) Nickel can be used to produce pipes that transport hot alkaline solutions

d) Polytetrafluroethylene can be used for underground water tanks

e) Aluminum is used because it is light weighted and exhibits corrosion resistivity to climate change
