Multiple choice questions: ions, and rusting
Can anyone tell me if I did these questions right? thanks
A solution contain Barium and Silver ions, what can the anion be?
D)All of the above
I chose A, is this right? http://www.chemistryhelpforum.com/ch...lies/smile.gif
1)Stainless steel is alloying iron with other metals, it prevents rusting by eliminating oxygen.
2)Methods of preventing rusting are electroplating, galvanizing and painting.
Which statement is correct?
A)Both, statement 2 explains statement 1
B)Both, but statement 2 doesn't explain statement 1
C)Statement 1 is right, statement 2 is wrong
D)Statement 2 is right, statement 1 is wrong
I was not sure, but I thought that the alloy does not "eliminate" oxygen, it just changed the structure in a way that would not allow it to become oxidized that easily. So I choose D, is this right?
