Okay, so this question asks us to determine the oxidizing ability of vanadium oxide, chromium oxide, and magnesium oxide.
00:11
And there are two ways to solve this problem.
00:15
The first one is to check the three elements reduction potential from appendix l from the textbook.
00:25
And i have already write down the three formulas for the reduction of the three.
00:31
Elements and we can see that for vanadium to reduce vanadium it takes negative 1 .190 volt and to reduce chromium it will take negative 0 .13 volt and for reducing the magnetase oxide the electron volt is positive 1 .507 volt so from the electron volt we know that magnetase oxide will be the most easily reduced compound among the three.
01:05
However, i think this is not the most straightforward way to solve the problem.
01:11
Another way is to look at the electron charge of each element.
01:15
So for the, so this is method number one and for method number two, we look at the electron, look at the charge of each element...
