In 1973 the wreckage of the Civil War ironclad USS Monitor was discovered near Cape Hatteras, North Carolina. [The Monitor and the CSS Virginia (formerly the USS Merrimack) fought the first battle between iron-armored ships.] In 1987 investigations were begun to see whether the ship could be salvaged. Time reported (June 22, 1987) that scientists were considering adding sacrificial anodes of zinc to the rapidly corroding metal hull of the Monitor. Describe how attaching zinc to the hull would protect the Monitor from further corrosion.
Answer to relevant QuestionsA standard galvanic cell is constructed so that the overall cell reaction is 2Al3+(aq) + 3M(s) → 3M2+(aq) + 2Al(s) where M is an unknown metal. If ΔGo = –411 kJ for the overall cell reaction, identify the metal used ...Give the standard line notation for each cell in Exercise 21. Exercise 21. You have a concentration cell with Cu electrodes and [Cu2+] = 1.00 M (right side) and 1.0 × 1024 M (left side). a. Calculate the potential for this cell at 25oC. b. The Cu21 ion reacts with NH3 to form Cu(NH3)42+, where the ...How is the standard quantity (SQ) computed in the calculation of the direct material usage variance?Discuss the use of throughput.
