What is the reaction for Na2SO4 BaCl2

Na2SO4 + BaCl2 ---> 2NaCl + BaSO4 :)

Which is least likely to be reduced

Idontremember is right, Na+ was correct for me on Apex

What is the standard reduction potential E for the half-reaction Al3 aq 3e- Als

How does the oxidation state of 0 change in the following reaction

It does not change.

In the redox reaction AgNO3 plus Na NaNo3 plus Ag which element has been reduced

Silver (Ag)

What is the oxidation half-reaction for 2Mg plus O22MgO

2Mg(s) + O2(g) ==> 2MgOMg ===> Mg^2+ + 2e- [x2 to balance electrons] = oxidation half reaction

O2 + 4e- ===> 2O^2-

So, the final oxidation half reaction will be:

2Mg(s) ===> 2Mg^2+ + 4e-
