The following statement is correct The melting point of A and tin bronze is higher than that of pure copper B. in the natural environment, tin in tin bronze protects copper C. bronze artifacts are more corrosive in moist environments than in dry environments D. formation of Cu2 (OH) 3Cl mulch is an electrochemical corrosion process, but not a chemical reaction process 2. (2009 Guangdong roll) can be used as an aluminum air fuel cell for electric vehicles, usually with NaCl solution or NaOH solution as solution, aluminum alloy as negative electrode, and air electrode as positive electrode. The following statement is correct A. with NaCl solution or NaOH solution, the positive reaction was: O22H2O4e = 4OH B. in a NaOH electrolyte, anode reaction: Al3OH3e = Al (OH): 3 When the NaOH solution is used as an electrolyte, the pH of the electrolyte remains unchanged during the operation of the C. battery When the D. battery works, the electrons flow from the anode to the negative through the outer circuit 3.
