1.You are fixing a piece of equipment on a cruiser that requires a zinc fitting. You rest the zinc fitting on a moist copper pipe. You return the next day and find that the zinc is corroded. This type of corrosion is best described as  

a.atmospheric corrosion.

b.chemical corrosion.

c.galvanic corrosion.

d.stress corrosion.

2. Battery acid spills on the deck of a destroyer. Identify the cathodic half-reaction that is expected to take place as part of a corrosion cell.

a. Fe(s) → Fe2+(aq) + 2 e–

b. Fe2+(aq) + 2 e– → Fe(s)

c. Fe2+(aq) + e– → Fe3+(aq)

d. 2 H+(aq) + 2 e– → H2(g)

e. O2(g) → 2 O(g) + 2 e–  

f. O2(g) + 2 H2O(l) + 4 e– → 4 OH–(aq)

We are studying the corrosion rate between a piece of copper and a piece of zinc by dipping them in water and using a DMM to measure the conductivity. In the first test electric potential was found, then the electrical current was found. My question is how to find corrosion rate? Given the equation Nzinc= I / 2(96485.33), I being the electrical current in amperes. I just want to know really if the information we obtained is enough, maybe could...

1. Select one piece of furniture and one piece of play equipment/toy you would select either for an infant room or a toddler room. Describe your selections and why you chose them. Then we can see how the class would collaboratively design an infant or a toddler environment! 2. Many parents don't understand the importance of construction play (such as blocks) for young children. In fact, a lot of preschool teachers see this area as a constant frustration (social conflict,...

You must evaluate the purchase of a proposed piece of equipment. The cost of the equipment is $50,000. The installation and transportation cost of bringing the equipment to its location is $6,000. The equipment falls into the MACRS 3-year class. The project is expected to increase revenues by $80,000 each year and increase operating costs (excluding depreciation) by $30,000 each year. This project leads to an increase in net operating working capital by $10,000. You can salvage the equipment for...
