Why is it not practical to use stainless steel to build structures such as bridges that are prone to corrosion?

Question 11 options:

stainless steel will corrode quickly if the protective coating is broken

the chromium used in stainless is too expensive

stainless steel is not strong enough

the carbon used to make stainless steel is too expensive

filled to 1.40 cm3

before he measured the volume of copper sulfate solution. Complete the table

below to show all the burette measurements that John would have taken.
