A copper pipe undergoes a chemical reaction and rusts. The pipe now weighs more than it did originally. Does this violate the law of conservation of mass? Why or why not?

What is no, because the extra mass is accounted for from the weight of the atoms like water and oxygen which is subtracted from the total weight of the atmosphere.
