Ba electrons are further from nucleus than Mg electrons so they are more readily lost.
Carbon dioxide is the reducing agent.
This is oxygen.
The oxidizing agent (reducing substance) is what does gain electrons, and it means more electronegative substance, and in this case, oxygen.
Quite good, just a bit better than Zinc, hardly better than Aluminum, and less than Sodium (Na), Ca, Ba, K and Li
The elements in group 1 are the strongest reducing agents. This is because they have one electron in their outer shell, which the wish to lose to gain a full outer shell. The strength of the reducing agents decreases going across a period and increases down a group.
This reducing agent.
it is a reducing agent
Magnesium can burn in the absence of elemental oxygen, yes. This is because it is such a strong reducing agent that it can essentially steal oxygen from substances such as water and carbon dioxide.
Magnesium is a stronger reducing agent than iron. The magnesium has a stronger tendency to take up the oxygen to form magnesium oxide than iron. Iron misses out on the oxygen until the magnesium is all used up.
Reducing
IN Ellingham diagram formation of zinc oxide curve appears below the curve of carbon monoxide so zinc is a better reducing agent
it is both oxidizing as well as reducing agent
