What kind of chemical reaction does wine have with some metal?

It will corrode the metal and cause chemical reaction, because there is a film on the surface of the metal vessel, because the film will not rust, and the alcohol will react with the film. When the film is gradually consumed, the original metal component will be exposed, and the water in the wine will oxidize with the metal, causing the metal to rust and contaminate the wine, so it is better not to use the metal vessel for wine.

The mass of ethanol participating in the chemical reaction is When ethanol (C2H5OH) is completely combusted, CO2 and H20 are generated. If oxygen is insufficient, ethanol combustion may also generate CO. The total mass of CO and CO2 in the ethanol combustion product is 25.2 g, and the mass ratio of carbon to oxygen is 2:5

In the mixture of 25.2 g of CO and CO2, the mass of carbon=25.2*2/7=7.2 g; the mass of oxygen=25.2-7.2=18 g; the mass of C=7.2/12=0.6 molO=18/16=0.6 mol O for 1.125mol0.6molC CO, and 1.125-0.6=0.525 mol O, therefore,0.525 mol CO2 can be produced.
