Question

2. Why does galvanized iron not rust?
3. Give three examples of desirable chemical
e. Why?​

Answer 1

Answer:

• Galvanization is the process of applying a protective zinc coating to steel or iron in order to prevent premature rust and corrosion. ... The corrosion of zinc is very slow, which gives it an extended life while it protects the base metal. Due to the alloying of the Zinc to the iron, cathodic protection occurs.
• Adjective The house is in a highly desirable location. The new stove has many desirable features.
