Question

20.Carbon cannot reduce the oxides of Sodium, magnesium and aluminium to their respective
metals. Why? Where are these metals placed in the reactivity series?
Also explain why Hydrogen gas is not evolved when metals react with Nitric acid?​

Answer 1

Answer:

hi mate Here is your answer ☺☺

Explanation:

In the reactivity series, sodium, magnesium and aluminium are placed in the upper portion which means these metals are very reactive in nature and carbon is less reactive. Oxides of reactive metals are directly put for electrolytic reduction process to obtain the pure metal.

Metals like Na, K, Ca and Mg are never found in their Ans. (b) (c) (d) (e) Q. ... Due to this, the reactivity of aluminium decreases. ... This ore should be roasted to obtain ...

Hope it helps you ✌

Answer 2

Answer:

here is the answer:

Na and Mg has less affinity towards carbon because these metals are highly reactive. So carbon cannot reduce the oxides of Sodium and Magnesium. Explanation: ... As a result, being less reactive in nature carbon is unable to reduce the oxides of sodium (Na) and magnesium (Mg)
